The efficient activity of Azadirachta indica and Mentha piperita essential oils, and a commercial formulation of Bacillus thuringiensis as biopesticide, were tested for their molluscicidal activity against two terrestrial snails’ E. vermiculata and T. pisana. The bioassay technique was performed using the Dipping leaves method to estimate LC 50 and LC 95 values against both terrestrial snails; E. vermiculata and T. pisana, under laboratory conditions. The obtained results indicated that the tested essential oils of A. indica and M. piperita were more toxic against T. pisana than E. vermiculata snails. Where, the deduced LC 50 values of A. indica were 0.87% and 2.37% for M. piperita against T. pisana. Likewise, against E. vermiculata were 2.26 and 9.523%, respectively after 72 h post treatment. On the other hand, the toxicity of B. thuringiensis was more effective against E. vermiculata than T. pisana snails, where the LC 50 values were 2.16% and 8.81%, respectively, after 72hrs post treatment. This study elucidated the promising efficient use of essential oils and or biopesticides in controlling the harmful gastropod pests.","PeriodicalId":156935,"journal":{"name":"Journal of the Advances in Agricultural Researches","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121821894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, the experimental work included two separate trial treatments. The first was directed for estimation the impact of the population dynamics, in addition to control above mentioned pest. While the second was directed to investigate the recent approach of agrochemical mixtures looking for new safe products against P. ulmi . On the first experimental trial, the results indicated three peaks of activity regarding the infestation by P. ulmi. The first peak occurred at the 2 nd week of May, the second peak was at the 2 nd week of August, while the third peak was at the 1 st week of October, during season 2020. Almost the same trend was obtained during season 2021. The reduction percent of infestation was 97.7% season 2020 and 97.9% season 2021, showed that Fenbutatin-oxide was the most potent and active product against the P. ulmi . Followed by Abamectin 90.3% season 2020 and 90.4% season 2021. Both compounds Sulfur and Petroleum oil, were the least effective compounds achieving 60% average reduction. The recent approach to use agrochemicals against of P. ulmi (Abamectin, Chitosan, K. silicate, Petroleum oil and Sulfur) in addition to use the mixtures of half dose of Abamectin plus fixed dose of Petroleum oil, while Abamectin and 3/4 dose of Sulfur used in the application. Full dose of Chitosan and K. silicate were investigated against P. ulmi . The data obtained indicated that (Abamectin + Chitosan) reduce the P. ulmi infection percent by 95.4% and (Abamectin + K. silicate) 94.6% were the most effective tested mixtures. Mixtures (Abamectin + P. oil) and (Abamectin + Sulfur) gave 93.7% and 92.6% infection reduction, respectively. Mixture (Chitosan + Sulfur) and (K. silicate + Sulfur) showed the least effective mixtures 82.9% and 81.8% infection reduction during the course of study2020. The days post-treatment (Abamectin + Chitosan) and (Abamectin + K. silicate) gave the most effective tested mixtures showed 95.2% and 94.1%, respectively. The reduction percent of P. ulmi showed that all mixtures gave considerable effect against of P. ulmi above 80%. Meanwhile, mixtures (Chitosan + Sulfur) and (K. silicate + Sulfur) showed the least effective mixtures 83.3% and 82.1% reduction duringthe course of study 2021, used as alternative for Fenbutatin-oxide for controlling of P. ulmi on apple crop.","PeriodicalId":156935,"journal":{"name":"Journal of the Advances in Agricultural Researches","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131051787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, Purpureocillium lilacinum Egyptian isolate bioactive constituents and its insect host range were estimated. The tested isolate was identified morphologically and molecularly by amplification of internal transcribed spacer (ITS) region using the polymerase chain reaction technique (PCR). The ITS sequence was compared with other Purpureocillium published isolates in genbank data base and our isolate showed that Purpureocillium lilacinum (MYS) (MT102250) isolate has 98% homology with most published isolates. The pathogenicity of the tested isolate P. lilacinum (MYS) was evaluated by using five concentrations of fungal spore suspensions and fungal filtrates against four pests, Bemisia tabaci, Tetranychus urticae, Thrips tabaci and Diuraphis noxia . The fungal filtrate had a higher toxic effect on all tested pests than the spore suspension. The greater fungal filtrate concentration resulted in higher mortality rates seven days post treatment, reached 100% for T. tabaci and T. urticae and 97% for B. tabaci and D. noxia , respectively. LC 50 values for spore suspension concentrations were 0.3x10 2 spore/ml for T. tabaci and T. urticae and 0.2x 10 3 and 0.2x10 2 spore/ml for B. tabaci and D. noxia respectively and were 2% for T. tabaci and B. tabaci and 5 and 9% for D. noxia and T. urticae respectively with culture filtrate concentrations.

The plant's central section indicated the maximum population density, whereas the plant's top section indicated the lowest population density. The population density of mites found on the undersides of the leaves was significantly higher than that of mites found on the upper sides of the leaves. The bases and pleats of the undersides of the leaves harboured the mite majority. Neither Lambda cyhalothrin (5%) E.C. nor Chlorpyrifos methyl (48%) E.C. had a significant effect on the mite numbers. A defoliant was sprayed in the pesticide-free area. A week later, the recently fallen leaves had the greatest mite population density. A few recently fallen leaves were collected from an area treated with both defoliant and the two pesticides. When they were stacked in a glass jar covered with opaque fabric apart from the opening, in a continuously lit laboratory, the majority of the mites congregated on the topmost leaves.","PeriodicalId":156935,"journal":{"name":"Journal of the Advances in Agricultural Researches","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133242517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most efficient design was based on providing the mites with a diet-saturated piece of thread connected to a little of the diet. For this, the piece of thread was passed through a 10 ml plastic pot containing a little of the diet. As soon as the piece of thread turns solid, it is pulled to be replaced with the next diet-saturated piece. By applying that design to feed the mites on a diet composed of skim milk, honey, yolk, baker's yeast, and amino acid solution 10% at a volume ratio of 100:1:1:20:1, respectively, the diet that saturated the piece of thread remained in the liquid phase for an average of three hours; then, it turned solid. The ability of the diet located in the pot, to saturate more thread, lasted for five hours; then, it coagulated. The percentage of the mites that congregated to feed on the diet, in 30 minutes, amounted to an average of 83.33%. No individual stuck to the diet-saturated thread within the liquid-phase span.
