The populations of whitefly were observed and recorded every hour up to 3 hours with insect net and yellow sticky traps after the treatments were applied. The results showed that bacteria ISR was the highest effectiveness for control whitefly infestation on culantro, the whitefly numbers on insect net were 12.5, 10.0, and 7.5 after spraying in 1hr, 2hr, and 3hr, respectively. While the whitefly on yellow sticky traps showed 15.0, 10.0, and 10.0 after spraying in 1hr, 2hr, and 3hr, respectively. Furthermore, overall the experiments showed that treatment of bacteria ISR found the average whitefly numbers only 8.06 and 11.0 on insect net and sticky tap respectively, followed by treatment of nematode found the average whitefly with 9.87 and 11.43 on the insect net and sticky tap, respectively. Therefore, the application of biopesticide from entomopathogenic nematodes, bacteria ISR, organic substances from plants and wood vinegar combined with natural enemies is the alternative method of Integrated Pest Management (IPM) for against infestation of whitefly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=whitefly%20%28Bemisia%20tabaci%20Gennadius%29" title="whitefly (Bemisia tabaci Gennadius)">whitefly (Bemisia tabaci Gennadius)</a>, <a href="https://publications.waset.org/abstracts/search?q=culantro%20%28Eryngium%20foetidum%20L.%29" title=" culantro (Eryngium foetidum L.)"> culantro (Eryngium foetidum L.)</a>, <a href="https://publications.waset.org/abstracts/search?q=entomopathogenic%20nematode%20%28Steinernema%20thailandensis%20n.%20sp.%29" title=" entomopathogenic nematode (Steinernema thailandensis n. sp.)"> entomopathogenic nematode (Steinernema thailandensis n. sp.)</a>, <a href="https://publications.waset.org/abstracts/search?q=bacteria%20ISR%20%28Pseudomonas%20fluorescens%29" title=" bacteria ISR (Pseudomonas fluorescens)"> bacteria ISR (Pseudomonas fluorescens)</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20vinegar" title=" wood vinegar"> wood vinegar</a>, <a href="https://publications.waset.org/abstracts/search?q=fermented%20organic%20substances" title=" fermented organic substances"> fermented organic substances</a> </p> <a href="https://publications.waset.org/abstracts/36589/effect-of-biopesticide-to-control-infestation-of-whitefly-bemisia-tabaci-gennadius-on-the-culantro-eryngium-foetidum-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36589.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">374</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Acute and Chronic Effect of Biopesticide on Infestation of Whitefly Bemisia tabaci (Gennadius) on the Culantro Cultivation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=U.%20Pangnakorn">U.

(variety DK 6818) was evaluated during the drought season. The experimental plots were located at research station of Faculty of Agriculture, Natural Resources and Environment, Naresuan University, Phitsanulok, Thailand. The extracted substance from plants was evaluated in the plots in 4 treatments: 1) water as control; 2) bitter bush (Chromolaena odorata L.); 3) neem (Azadirachta indica A. Juss), 4) golden shower (Cassia fistula Linn.). The experiment was followed a Randomized Complete Block Design (RCBD) with 4 treatments and 4 replications per treatment. The results showed that golden shower gave the highest growth of maize in term of height (203.29 cm), followed by neem and bitter bush with average height of 202.66 cm and 191.66 cm respectively with significance different. But neem treatment given significantly higher average of yield component in term of length, width, and weight of pod corn with 18.89 cm 13.91 cm and 166.46 g respectively. Also, treatment of neem showed the highest harvested yield at 284.06 kg/ha followed by the golden shower and bitter bush with harvested yield at 245.86 kg/ha and 235.52 kg/ha respectively. Additionally, treatment of neem and golden shower were the highest effectiveness for reducing insects pest infestation of maize: corn leaf aphid Rhopalosiphum maidis Fitch, corn borer Ostrinia fumacalis Guenee and corn armyworm Mythimna separata Walker. The treatment of neem, golden shower, and bitter bush given reduction insect infestation on maize with leaves area were infested at 5,412 mm², 6,827 mm² and 8,910 mm² respectively with significance different when compared to control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maize" title="maize">maize</a>, <a href="https://publications.waset.org/abstracts/search?q=Zea%20mays%20Linn." title=" Zea mays Linn."> Zea mays Linn.</a>, <a href="https://publications.waset.org/abstracts/search?q=biopesticide" title=" biopesticide"> biopesticide</a>, <a href="https://publications.waset.org/abstracts/search?q=bitter%20bush" title=" bitter bush"> bitter bush</a>, <a href="https://publications.waset.org/abstracts/search?q=Chromolaena%20odorata%20L.%29" title=" Chromolaena odorata L.)"> Chromolaena odorata L.)</a>, <a href="https://publications.waset.org/abstracts/search?q=neem" title=" neem"> neem</a>, <a href="https://publications.waset.org/abstracts/search?q=Azadirachta%20indica%20A.%20Juss" title=" Azadirachta indica A.

Therefore, a biopesticide prototype based on B. bassiana strain Bv060 was developed at Corpoica laboratories. For the production of B. bassiana conidia, a baseline fermentation was performed at laboratory in a solid medium using broken rice as a substrate, a temperature of 25±2 °C and a relative humidity of 60±10%. The experimental design was completely randomized, with a three-time repetition. These culture conditions resulted in an average conidial concentration of 1.48x10^10 conidia/g, a yield of 13.07 g/kg dry substrate and a productivity of 8.83x10^7 conidia/g*h were achieved. Consequently, the objective of this study was to evaluate the influence of the particle size reduction of rice (<1 mm) and the addition of a complex nitrogen source over conidia production and efficiency parameters in a solid-state fermentation, in a completely randomized experiment with a three-time repetition. For this aim, baseline fermentation conditions of temperature and humidity were employed in a semisolid culture medium with powdered rice (10%) and a complex nitrogen source (8%). As a result, it was possible to increase conidial concentration until 9.87x10^10 conidia/g, yield to 87.07 g/g dry substrate and productivity to 3.43x10^8 conidia/g*h. This suggested that conidial concentration and yield in semisolid fermentation increased almost 7 times compared with baseline while the productivity increased 4 times. Finally, the designed system for semisolid-state fermentation allowed to achieve an easy conidia recovery, which means reduction in time and costs of the production process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beauveria%20bassiana" title="Beauveria bassiana">Beauveria bassiana</a>, <a href="https://publications.waset.org/abstracts/search?q=biopesticide" title=" biopesticide"> biopesticide</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20state%20fermentation" title=" solid state fermentation"> solid state fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=semisolid%20medium%20culture" title=" semisolid medium culture"> semisolid medium culture</a> </p> <a href="https://publications.waset.org/abstracts/57293/biomass-production-improvement-of-beauveria-bassiana-at-laboratory-scale-for-a-biopesticide-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57293.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">301</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Comparative Toxicity of Garlic Juice and Dicofol to Population of Citrus Mites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20Atibi">Y.

Garlic and onion are known for their positive effect on health, including the prevention of cardiovascular disease and some digestive cancers. These health benefits molecules are also responsible for pest potential control of Alliaceae. With these properties, we can consider using Alliaceae as acaricides. The purpose of this study was to compare the effect of chemical and biopesticides on citrus mites, especially Tetranychus urticae, Panonychus citri and Eutetranychus orientalis. Chemical treatment (Dicofol) and biopesticides (Garlic juice + Alcohol) applied on this study to control the various stages of mites, have reduced the proliferation of mobile forms and reducing the number of eggs to acceptable levels. Garlic juice + alcohol revealed efficiency from 50 to 57.69 % against the mobile forms of T. urticae, however, it was effective against the mobile forms of P. citri and E. orientalis with an efficiency of 85.71 % and 100 % respectively, its action has also reduced the number of eggs of T. urticae and E. orientalis at low levels. Therefore, this biopesticide is conceivable viewpoint technical and economic as the infestation by mite is low. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Garlic%20juice" title="Garlic juice">Garlic juice</a>, <a href="https://publications.waset.org/abstracts/search?q=acaricide" title=" acaricide"> acaricide</a>, <a href="https://publications.waset.org/abstracts/search?q=biopesticide" title=" biopesticide"> biopesticide</a>, <a href="https://publications.waset.org/abstracts/search?q=mites" title=" mites"> mites</a>, <a href="https://publications.waset.org/abstracts/search?q=alcohol" title=" alcohol"> alcohol</a>, <a href="https://publications.waset.org/abstracts/search?q=Tetranychus%20urticae" title=" Tetranychus urticae"> Tetranychus urticae</a>, <a href="https://publications.waset.org/abstracts/search?q=Panonychus%20citri" title=" Panonychus citri"> Panonychus citri</a>, <a href="https://publications.waset.org/abstracts/search?q=Eutetranychus%20orientalis." title=" Eutetranychus orientalis."> Eutetranychus orientalis.</a> </p> <a href="https://publications.waset.org/abstracts/19515/comparative-toxicity-of-garlic-juice-and-dicofol-to-population-of-citrus-mites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19515.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">524</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Effectiveness of Biopesticide against Insects Pest and Its Quality of Pomelo (Citrus maxima Merr.) </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=U.%20Pangnakorn">U.

The selected pomelo was carried out for insects pest control and its quality. The experimental site was located at farmer’s orchard in Phichit Province, Thailand. This study was undertaken during the drought season (December to March). The extracted from plants and wood vinegar were evaluated in 6 treatments: 1) water as control; 2) wood vinegar; 3) S. tuberosa Lour; 4) T. crispa Mier; 5) D. elliptica Roxb; 6) mixed (wood vinegar + S. tuberosa Lour + T. crispa Mier + D. elliptica Roxb). The experiment was RCB with 6 treatments and 3 replications per treatment. The results showed that T. crispa Mier was the highest effectiveness for reduction population of thrips (Scirtothrips dorsalis Hood) and citrus leaf miner (Phyllocnistis citrella Stainton) at 14.10 and 15.37 respectively, followed by treatment of mixed, D. elliptica Roxb, S. tuberosa Lour and wood vinegar with significance different. Additionally, T. crispa Mier promoted the high quality of harvested pomelo in term of thickness of skin at 12.45 mm and S. tuberosa Lour gave the high quality of the pomelo in term of firmness (276.5 kg/cm2) and brix (11.0%). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wood%20vinegar" title="wood vinegar">wood vinegar</a>, <a href="https://publications.waset.org/abstracts/search?q=medicinal%20plants" title=" medicinal plants"> medicinal plants</a>, <a href="https://publications.waset.org/abstracts/search?q=Pomelo%20%28Citrus%20maxima%20Merr.%29" title=" Pomelo (Citrus maxima Merr.)"> Pomelo (Citrus maxima Merr.)</a>, <a href="https://publications.waset.org/abstracts/search?q=Thrips%20%28Scirtothrips%20dorsalis%20Hood%29" title=" Thrips (Scirtothrips dorsalis Hood)"> Thrips (Scirtothrips dorsalis Hood)</a>, <a href="https://publications.waset.org/abstracts/search?q=citrus%20leaf%20miner%20%28Phyllocnistis%20citrella%20Stainton%29" title=" citrus leaf miner (Phyllocnistis citrella Stainton) "> citrus leaf miner (Phyllocnistis citrella Stainton) </a> </p> <a href="https://publications.waset.org/abstracts/26281/effectiveness-of-biopesticide-against-insects-pest-and-its-quality-of-pomelo-citrus-maxima-merr" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26281.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">373</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> The Social Ecology of Serratia entomophila: Pathogen of Costelytra giveni</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Watson">C.

Hurst</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The endemic New Zealand grass grub (Costelytra giveni, Coleoptera: Scarabaeidae) is an economically significant grassland pest in New Zealand. Due to their impacts on production within the agricultural sector, one of New Zealand's primary industries, several methods are being used to either control or prevent the establishment of new grass grub populations in the pasture. One such method involves the use of a biopesticide based on the bacterium Serratia entomophila. This species is one of the causative agents of amber disease, a chronic disease of the larvae which results in death via septicaemia after approximately 2 to 3 months. The ability of S. entomophila to cause amber disease is dependant upon the presence of the amber disease associated plasmid (pADAP), which encodes for the key virulence determinants required for the establishment and maintenance of the disease. Following the collapse of grass grub populations within the soil, resulting from either natural population build-up or application of the bacteria, non-pathogenic plasmid-free Serratia strains begin to predominate within the soil. Whilst the interactions between S. entomophila and grass grub larvae are well studied, less information is known on the interactions between plasmid-bearing and plasmid-free strains, particularly the potential impact of these interactions upon the efficacy of an applied biopesticide. Using a range of constructed strains with antibiotic tags, in vitro (broth culture) and in vivo (soil and larvae) experiments were conducted using inoculants comprised of differing ratios of isogenic pathogenic and non-pathogenic Serratia strains, enabling the relative growth of pADAP+ and pADAP- strains under competition conditions to be assessed. In nutrient-rich, the non-pathogenic pADAP- strain outgrew the pathogenic pADAP+ strain by day 3 when inoculated in equal quantities, and by day 5 when applied as the minority inoculant, however, there was an overall gradual decline in the number of viable bacteria for both strains over a 7-day period. Similar results were obtained in additional experiments using the same strains and continuous broth cultures re-inoculated at 24-hour intervals, although in these cultures, the viable cell count did not diminish over the 7-day period. When the same ratios were assessed in soil microcosms with limited available nutrients, the strains remained relatively stable over a 2-month period. Additionally, in vivo grass grub co-infections assays using the same ratios of tagged Serratia strains revealed similar results to those observed in the soil, but there was also evidence of horizontal transfer of pADAP from the pathogenic to the non-pathogenic strain within the larval gut after a period of 4 days. Whilst the influence of competition is more apparent in broth cultures than within the soil or larvae, further testing is required to determine whether this competition between pathogenic and non-pathogenic Serratia strains has any influence on efficacy and disease progression, and how this may impact on the ability of S. entomophila to cause amber disease within grass grub larvae when applied as a biopesticide. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biological%20control" title="biological control">biological control</a>, <a href="https://publications.waset.org/abstracts/search?q=entomopathogen" title=" entomopathogen"> entomopathogen</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20ecology" title=" microbial ecology"> microbial ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=New%20Zealand" title=" New Zealand"> New Zealand</a> </p> <a href="https://publications.waset.org/abstracts/118563/the-social-ecology-of-serratia-entomophila-pathogen-of-costelytra-giveni" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118563.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">156</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Role of Microbial Pesticides in Pest Control and Their Advantages and Disadvantages in Nature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatimah%20M.%20Alshehrei">Fatimah M.

Lately, biopesticides have emerged as possible substitutes for petrochemical pesticides. The sources of biopesticides are widely accessible, easily biodegradable, have a variety of modes of action, are less expensive, and have little toxicity toward humans and other creatures that aren't the intended targets. Plants, bacteria, and insects are used to create biopesticides, they used in controlling diseases in crops. Microbial pesticides are produced from different microorganisms such as Trichoderma, Bacillus, Pseudomonas, and Beauveria. Also, botanical pesticides have already been commercialized; they are extracted from neem, pyrethrum, azadirachtin, etc. This paper describes biopesticide categories, their sources, mode of action, advantages and disadvantages, and their role in sustainable agriculture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biopesticides%20categories" title="biopesticides categories">biopesticides categories</a>, <a href="https://publications.waset.org/abstracts/search?q=formulation" title=" formulation"> formulation</a>, <a href="https://publications.waset.org/abstracts/search?q=mode%20of%20action" title=" mode of action"> mode of action</a>, <a href="https://publications.waset.org/abstracts/search?q=pest%20control" title=" pest control"> pest control</a> </p> <a href="https://publications.waset.org/abstracts/182021/role-of-microbial-pesticides-in-pest-control-and-their-advantages-and-disadvantages-in-nature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182021.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">63</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Impact of a Biopesticide Formulated an Entomopathogenic Fungus Metarhizium Anisopliae et Abstracts of Two Different Plants Sage (Salvia officinalis) and American Paper (Schinus molle) on Aphis Fabae (Homoptera - Aphididae)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hicham%20Abidallah">Hicham Abidallah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work we realized a formulation of an entomopathogenic fungus Metarhizium anisopliae with a dose of 1,7 x 105 spores/ml, and aqueous abstracts of two different plants sage (Salvia officinalis) and American paper (Schinus molle) with they’re full dose and half dose, on a black bean aphid populations (Aphis fabae) on a bean crop planted in pots at semi-controlled conditions.

They are considered to have lower toxicity than traditional pesticides. After almost a century of pesticides use, resistances to traditional insecticides are wide spread, while those to bioinsecticides have raised less attention, and resistance management is frequently neglected. This seems to be a crucial mistake since resistances have already occurred for many marketed biopesticides. With an eye to the future, we present here a selection of new natural occurring chemicals as potential bioinsecticides. The molecules were selected using a consolidated mathematical paradigm called molecular topology. Several QSAR equations were depicted and subsequently applied for the virtual screening of hundred thousands molecules of natural origin, which resulted in the selection of new potential bioinsecticides. The most innovative aspect of this work does not only reside in the importance of the identification of new molecules overcoming biopesticides’ resistances, but on the possibility to promote shared knowledge in the field of green chemistry through this unique in silico discipline named molecular topology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20chemistry" title="green chemistry">green chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=QSAR" title=" QSAR"> QSAR</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20topology" title=" molecular topology"> molecular topology</a>, <a href="https://publications.waset.org/abstracts/search?q=biopesticide" title=" biopesticide"> biopesticide</a> </p> <a href="https://publications.waset.org/abstracts/60275/naturally-occurring-chemicals-in-biopesticides-resistance-control-through-molecular-topology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60275.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">314</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Study of the Toxic Activity of the Entomopathogenic Fungus Beauveria bassiana on the Wistar Rat Rattus norvegicus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Haddadj">F.

Due to its persistence in soil and its apparent human and animal safety, Beauveria bassiana is a cryptogram used for controlling pests organizations, particularly in the locust where its effectiveness has been proven. This fungus is also called for greater respect for biotic communities and the environment. Indeed, biopesticides have several environmental benefits: biodegradability, their activity and selectivity decrease unintended non-target species effects, decreased resistance to some of them. It is in this sense that we contribute by presenting our work on the safety of B. bassiana against mammals. For this we conducted a toxicological study of this fungus strain on Wistar rats Rattus norvegicus, first its effect on weight gain. In a second time were performed histological target organ is the liver. After 20 days of treatment, the results of the toxicological studies have shown that B. bassiana caused no change in the physiological state of rats or weight gain, behavior and diet.

To reduce the inconveniences produced by these pesticides, the use of "biopesticides" originated from plants could be an alternative. The aim of this work is the valuation of a botanical species: Eucalyptus camaldulensis from Northeastern Algeria which extracts are supposed to have an antimicrobial activity, similar to pesticides. The extraction of secondary metabolites from the leaves of E. camaldulensis was realized using methanol and water, and measurements of total polyphenols were made by spectrometric method. Determination of the antimicrobial activity of the extracts at issue was realized in vitro on phyto-pathogenic fungal and bacterial stumps. Tests of comparison were included in the essays by using the chemical pesticidal products of synthesis. The obtained results show that the plant contains polyphenols with an efficiency mattering of the order of 22 %. These polyphenols have a strong fungicidal and bactericidal pesticidal activity against various microbial stumps and the values of the zones of inhibition are more important compared with that obtained in the presence of the chemicals of synthesis (fungicide). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eucalyptus%20camaldulensis" title="eucalyptus camaldulensis">eucalyptus camaldulensis</a>, <a href="https://publications.waset.org/abstracts/search?q=biopesticide" title=" biopesticide"> biopesticide</a>, <a href="https://publications.waset.org/abstracts/search?q=polyphenols" title=" polyphenols"> polyphenols</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activity" title=" antimicrobial activity"> antimicrobial activity</a> </p> <a href="https://publications.waset.org/abstracts/29478/study-of-the-antimicrobial-activity-of-the-extract-of-the-eucalyptus-camaldulensis-stemming-from-the-algerian-northeast" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29478.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">432</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Toxic Activity of the Entomopathogenic Fungus Beauveria bassiana on the Wistar Rat Rattus norvegicus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Haddadj">F.

Due to its persistence in soil and its apparent human and animal safety, Beauveria bassiana is a cryptogram used for controlling pests organizations, particularly in the locust where its effectiveness has been proven by several highly studies. This fungus is also called for greater respect for biotic communities and the environment. Indeed, biopesticides have several environmental benefits: biodegradability, their activity and selectivity decrease unintended non-target species effects, decreased resistance to some of them. It is in this sense that we contribute by presenting our work on the safety of B. bassiana against mammals. For this we conducted a toxicological study of this fungus strain on Wistar rats Rattus norvegicus, first its effect on weight gain. In a second time were performed histological target organ is the liver. After 20 days of treatment, the results of the toxicological studies have shown that B. bassiana caused no change in the physiological state of rats or weight gain, behavior and diet. On cuts in liver histology revealed no disturbance on the organ. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entomopathogenic%20fungus" title="entomopathogenic fungus">entomopathogenic fungus</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20bassiana" title=" B. bassiana"> B. bassiana</a>, <a href="https://publications.waset.org/abstracts/search?q=Rattus%20norvegicus" title=" Rattus norvegicus"> Rattus norvegicus</a>, <a href="https://publications.waset.org/abstracts/search?q=toxicological%20study" title=" toxicological study"> toxicological study</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a> </p> <a href="https://publications.waset.org/abstracts/30997/toxic-activity-of-the-entomopathogenic-fungus-beauveria-bassiana-on-the-wistar-rat-rattus-norvegicus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30997.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">315</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Effect of Four Medicinal Plant Extracts on Chickpea Leaf Miner Liriomyza cicerina (Rondani)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabraoui%20Abdelhadi">Sabraoui Abdelhadi</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Bouhssini%20Mustapha"> El Bouhssini Mustapha</a>, <a href="https://publications.waset.org/abstracts/search?q=Lhaloui%20Saadia"> Lhaloui Saadia</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Fakhouri%20Karim"> El Fakhouri Karim</a>, <a href="https://publications.waset.org/abstracts/search?q=Bouchelta%20Aziz"> Bouchelta Aziz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The surveys carried out in 2014, 2015 in the regions of Abda- Doukala, Chaouia- Ouardigha, Zemour- Zair and Fes- Sais have confirmed that the leaf miner was the main insect pest attacking chickpea (Cicer arietinum L.) in Morocco. The grain yield losses caused by this pest could be more than 20% for winter planting and more than 42% for spring-sown crop. To reduce the chickpea leaf miner infestations, four essential oils, as biopesticide alternatives, were tested for their insecticidal effect on L. ciccerina, adults and larvae under laboratory conditions. In addition, we assessed the efficacy of these essential oils with and without adjuvant against this pest in comparison to three insecticides under field conditions. Mentha pulegium, with a dose of 33 µl/l of air caused 100% mortality on adults and larvae, after three hours and six hours of exposure, respectively. Eucalyptus showed 100% mortality on adults and larvae, with doses of 33 and 83 µl/l, after six and three hours of exposure, respectively. In the field conditions M. pulegium and E. globulus with adjuvant showed promising results compared with Abamectin, Azadirachtin and Spinetoram respectively. Essential oils could be used as one of the IPM components for the control of chickpea leaf miner. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liriomyza%20cicerina" title="Liriomyza cicerina">Liriomyza cicerina</a>, <a href="https://publications.waset.org/abstracts/search?q=chickpea" title=" chickpea"> chickpea</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20oils" title=" essential oils"> essential oils</a>, <a href="https://publications.waset.org/abstracts/search?q=insecticidal%20activity" title=" insecticidal activity"> insecticidal activity</a>, <a href="https://publications.waset.org/abstracts/search?q=Morocco" title=" Morocco"> Morocco</a> </p> <a href="https://publications.waset.org/abstracts/64444/effect-of-four-medicinal-plant-extracts-on-chickpea-leaf-miner-liriomyza-cicerina-rondani" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64444.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">372</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Essential Oil Encapsulated into Succinic Acid Modified Beta-Cyclodextrin: Characterization, Docking Study, and Antifungal Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amine%20Ez-Zoubi">Amine Ez-Zoubi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdellah%20Farah"> Abdellah Farah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Because of their effectiveness and environmental safety, many essential oils have been investigated as biopesticides. Nevertheless, the encapsulation process is necessary to improve its physical, chemical, and biological properties. Therefore, the purpose of this paper was to study the physicochemical characteristics, and antifungal activity of the Artemisia Herba-Alba essential oil (HAEO) encapsulated in succinic acid modified β-CD (SACD). A yellowish oil was obtained from plant A. Herba-Alba using hydrodistillation and GC-MS was used to identify the chemical composition, in which α-Thujone (65.0%) was the main component in HAEO. The succinic acid has been esterified via the hydroxyl groups in β-CD to produce SACD. In addition, the inclusion complex formation of HAEO and SACD was generated according to the co-precipitation method and was analyzed by several techniques. The antifungal activity in vitro was examined against Botrytis cinerea by direct contact with a potato dextrose agar culture medium. At a 0.1 % concentration, the HAEO in encapsulated form showed higher potential for the control of B. cinerea when compared to the EO in free form (38.34 to 12%). Thus, these results produced evidence that the encapsulation of EOs in SACD can be useful for the development of B.cinerea inhibitors and a promising alternative biopesticide. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Artemisia%20Herba-Alba%20essential%20oil" title="Artemisia Herba-Alba essential oil">Artemisia Herba-Alba essential oil</a>, <a href="https://publications.waset.org/abstracts/search?q=succinic%20acid%20modified%20%CE%B2-cyclodextrin" title=" succinic acid modified β-cyclodextrin"> succinic acid modified β-cyclodextrin</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusion%20complex" title=" inclusion complex"> inclusion complex</a>, <a href="https://publications.waset.org/abstracts/search?q=co-precipitation" title=" co-precipitation"> co-precipitation</a>, <a href="https://publications.waset.org/abstracts/search?q=Botrytis%20cinerea" title=" Botrytis cinerea"> Botrytis cinerea</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20contact" title=" direct contact"> direct contact</a> </p> <a href="https://publications.waset.org/abstracts/159612/essential-oil-encapsulated-into-succinic-acid-modified-beta-cyclodextrin-characterization-docking-study-and-antifungal-activity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159612.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">87</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Contribution to the Production of Phenazine Antibiotics Effect Type Compounds by Some Strains of Pseudomonas spp.fluorescent</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nac%C3%A9ra%20Benoussaid">Nacéra Benoussaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Lehalali%20Meriem"> Lehalali Meriem</a>, <a href="https://publications.waset.org/abstracts/search?q=Benchabane%20Messaoud"> Benchabane Messaoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Our work focuses on the production of compound antibiotic effect of volatile nature namely hydrogen cyanide and the production and identification of molecules phénazinique by some strains of fluorescent Pseudomonas spp isolated from the rhizosphere of some trees for a possible use as bio pesticides antifungal effect and/or antibiotic. We tested the production of hydrogen cyanide of 21 strains of Pseudomonas spp. fluorescent among them 19 strains (90, 47%) showed a positive cyanogenesis.The antagonism test executed in vitro showed that Pseudomonas strains have a higher anti fungal effect relative to their antibacterial effect with diameters of inhibition zones up to 3, 9 cm recorded by the strain F48 against Coleosporiumsp compared with recorded results against bacteria with a maximum inhibition of 1, 26 cm among this antagonistic strain.Three strains were selected by testing for producing phénazines namely PI9, BB9 and F20. The effect of the antimicrobial activity was performed on different culture media (GN, King B, ISP2 and PDA). The results of our study allowed us to retain the King B medium as ideal medium for the production of secondary metabolite. The produced phenazinique compounds was extracted from various organic solvents, and after the results of antibiographie against germs - targets, the extracts of ethyl acetate gave the best results compared to dichloromethane and hexane.The Analysis of these compounds of antibiotic phenazinique effect within layer chromatography (CCM) and high performance liquid chromatography( HPLC) indicate that both strains PI9 and F20 are productive of phenazine-1-carboxylic acid (PCA).

The spongy moth (Lymantria dispar) is a damaging invasive pest that can weaken and destroy trees by defoliating them. Chemical pesticides commonly used to protect forests against spongy moths not only have a negative impact on terrestrial and aquatic organisms/ecosystems but also often fail to provide significant protection. Therefore, many eco-friendly alternatives have been considered. Within this research, a new biopesticide was developed based on the method of nanoencapsulation of plant extracts in a biopolymer matrix, which provides a slow release of the active components during a substantial time period. The antifeedant activity of plant extracts of common (Fraxinus excelsior L.), manna (F. ornus L.) ash tree, and the tree of heaven Ailanthus altissima (Mill.) was tested on the spongy moth (Lymantria dispar L, 1758) larvae. To test the antifeedant activity of these compounds, the choice and non-choice tests in laboratory conditions for different plant extract concentrations (0.01, 0.1, 0.5, and 1 % v/v) were carried out. In both cases, the best results showed formulations based on the tree of heaven and common ash for the concentration of 1%, with deterioration indices of 163 and 132, respectively. The main benefit of these formulations is their versatility, effectiveness, prolonged effect, and because they are completely environmentally acceptable. Therefore, they can be considered for suppression of the spongy moth in forest ecosystems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ailanthus%20altissima%20%28Mill.%29" title="Ailanthus altissima (Mill.)">Ailanthus altissima (Mill.)</a>, <a href="https://publications.waset.org/abstracts/search?q=Fraxinus%20excelsior%20L." title=" Fraxinus excelsior L."> Fraxinus excelsior L.</a>, <a href="https://publications.waset.org/abstracts/search?q=encapsulation" title=" encapsulation"> encapsulation</a>, <a href="https://publications.waset.org/abstracts/search?q=Lymantria%20dispar" title=" Lymantria dispar"> Lymantria dispar</a> </p> <a href="https://publications.waset.org/abstracts/171972/antifeedant-activity-of-plant-extracts-on-the-spongy-moth-lymantria-dispar-larvae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171972.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">77</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Encapsulated Western Red Cedar (Thuja Plicata) Essential Oil as a Prospective Biopesticide against Phytophthora Pathogens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aleksandar%20M.%20Radojkovi%C4%87">Aleksandar M.

With the rapidly growing international trade in plants and the ongoing impacts of climate change, the harmful effects of plant pathogens of the genus Phytophthora are increasing, damaging the biodiversity and sustainability of forest ecosystems. This genus is one of the most destructive plant pathogens, causing the majority of fine root (66%) and collar rot diseases (90%) of woody plant species worldwide. Eco-friendly biopesticides, based on plant-derived products, such as essential oils (EOs), are one of the promising solutions to this problem. In this study, among three different EOs investigated (Chamaecyparis lawsoniana (A. Murr.) Parl., Thuja plicata Donn ex D.Don and Juniperus communis L.), western red cedar (Thuja plicata) essential oil almost completely inhibited the growth of three Phytophthora species (P. plurivora Jung and Burgess, P. quercina Jung, and P. ×cambivora (Petri) Buisman) during seven days of exposure for the EO concentrations of 0.1% and 0.5% (v/v). To prolong the inhibiting effect, Thuja plicata EO was encapsulated into a biopolymer matrix consisting of a chitosan-gelatin mixture to form a water-in-oil emulsion. This approach allowed the prolonged effect of the essential oil by its slow release from the biopolymer matrix and protection of the active components from atmospheric influences. Thus, it was demonstrated that encapsulated Thuja plicata EO consisting of sustainable bioproducts is efficient in controlling of Phytophthora species and can be considered a means of protection in natural and semi-natural ecosystems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emulsions" title="emulsions">emulsions</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20oils" title=" essential oils"> essential oils</a>, <a href="https://publications.waset.org/abstracts/search?q=phytophthora" title=" phytophthora"> phytophthora</a>, <a href="https://publications.waset.org/abstracts/search?q=thuja%20plicata" title=" thuja plicata"> thuja plicata</a> </p> <a href="https://publications.waset.org/abstracts/171742/encapsulated-western-red-cedar-thuja-plicata-essential-oil-as-a-prospective-biopesticide-against-phytophthora-pathogens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171742.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Insectivorous Medicinal Plant Drosera Ecologyand its Biodiversity Conservation through Tissue Culture and Sustainable Biotechnology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sushil%20Pradhan">Sushil Pradhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biotechnology contributes to sustainable development in several ways such as biofertilizer production, biopesticide production and management of environmental pollution, tissue culture and biodiversity conservation in vitro, in vivo and in situ, Insectivorous medicinal plant Drosera burmannii Vahl belongs to the Family-Droseraceae under Order-Caryophyllales, Dicotyledoneae, Angiospermeae which has 31 (thirty one) living genera and 194 species besides 7 (seven) extinct (fossil) genera. Locally it is known as “Patkanduri” in Odia. Its Hindi name is “Mukhajali” and its English name is “Sundew”. The earliest species of Drosera was first reported in 1753 by Carolous Linnaeus called Drosera indica L (Indian Sundew). The latest species of Drosera reported by Fleisch A, Robinson, AS, McPherson S, Heinrich V, Gironella E and Madulida D.A. (2011) is Drosera ultramafica from Malaysia. More than 50 % species of Drosera have been reported from Australia and next to Australia is South Africa. India harbours only 3 species such as D. indica L, Drosera burmannii Vahl and D. peltata L. From our Odisha only D. burmannii Vahl is being reported for the first time from the district of Subarnapur near Sonepur (Arjunpur Reserve Forest Area). Drosera plant is autotrophic but to supplement its Nitrogen (N2) requirement it adopts heterotrophic mode of nutrition (insectivorous/carnivorous) as well. The colour of plant in mostly red and about 20-30cm in height with beautiful pink or white pentamerous flowers. Plants grow luxuriantly during November to February in shady and moist places near small water bodies of running water stream. Medicinally it is a popular herb in the locality for the treatment of cold and cough in children in rainy season by the local Doctors (Kabiraj and Baidya). In the present field investigation an attempt has been made to understand the unique reproductive phase and life cycle of the plant thereby planning for its conservation and propagation through various techniques of tissue culture and biotechnology. More importantly besides morphological and anatomical studies, cytological investigation is being carried out to find out the number of chromosomes in the cell and its genomics as there is no such report as yet for Drosera burmannii Vahl. The ecological significance and biodiversity conservation of Drosera with special reference to energy, environmental and chemical engineering has been discussed in the research paper presentation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=insectivorous" title="insectivorous">insectivorous</a>, <a href="https://publications.waset.org/abstracts/search?q=medicinal" title=" medicinal"> medicinal</a>, <a href="https://publications.waset.org/abstracts/search?q=drosera" title=" drosera"> drosera</a>, <a href="https://publications.waset.org/abstracts/search?q=biotechnology" title=" biotechnology"> biotechnology</a>, <a href="https://publications.waset.org/abstracts/search?q=chromosome" title=" chromosome"> chromosome</a>, <a href="https://publications.waset.org/abstracts/search?q=genome" title=" genome"> genome</a> </p> <a href="https://publications.waset.org/abstracts/24677/insectivorous-medicinal-plant-drosera-ecologyand-its-biodiversity-conservation-through-tissue-culture-and-sustainable-biotechnology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24677.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">383</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> A Potential Bio-Pesticidal Molecule Derived from Indian Traditional Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bunindro%20Nameirakpam">Bunindro Nameirakpam</a>, <a href="https://publications.waset.org/abstracts/search?q=Sonia%20Sougrapakam"> Sonia Sougrapakam</a>, <a href="https://publications.waset.org/abstracts/search?q=Shannon%20B.%20Olsson"> Shannon B.

Despite a large number of plants that show insecticidal activity and diversity of natural chemistry with inherent eco-friendly nature, newer classes of insecticides have eluded discovery. Artemisia vulgaris, known as Mugwort, is a universal herb used for folk medicine and religious purposes throughout the ancient world. In India, the essential oils of Artemisia vulgaris are used for its insecticidal, anti parasiticidal and antimicrobial properties. Traditionally, the dried leaves of Artemisia vulgaris are used to repel insects as well as rats in and around the granaries in the North-East India. Artemisia vulgaris collected during November from different ecological sites were studied for the bio-pesticidal utility against the stored grain pests. The insecticidal activities were found in the crude extracts of n-hexane and methanol from the samples collected in Sikkim and Manipur respectively. Using silica gel column chromatography protocol, we have isolated one novel bioactive molecule from the aerial parts of Artemisia vulgaris L based on various physical-chemical and spectroscopic techniques (IR, 1H NMR, 13C NMR and mass). The novel bioactive molecule is highly toxic and very low concentration (4.35 µg/l) is needed to control the stored product insects. In additional experiment results clearly showed the involvement of sodium pumps inhibition in the insecticidal action of purified compound in the Sitophilus oryzae. The knockdown activity of the purified compound is concomitant with the in vivo inhibition of Na+/ K+- ATPase. Further, our study showed insignificant differences in the seed germination of control and the treated grains. The lack of adverse effect of the novel bioactive molecule on the seed germination is highly desirable for seed/grain protectant and showing the potential to be developed as possible natural fumigants for the control of stored grain pests. The novel bioactive molecule is selective insecticide with a high margin of safety to mammals and showed promise as novel biopesticide candidate for grain protection. It is believed that Bio-pesticides can serve as the most important pest management tools as far as global safety is concerned. <p class="card-text"><strong>Keywords:</strong> <a
