Conversely, the control of fungal fermentation processes to produce quality chitin makes fungal mycelia an attractive alternative source. Our study examined the production of chitin from mycelia of different fungal isolates recovered from soil samples collected from different places in El-Beheira Governorate, Egypt, during 2021 . Among the 21 isolate 9 were identified with standard key and microbial expert and because these isolates are pure isolates.In batch culture, isolates were screened to determine the fastest growing and greatest chitin‐yielding fungi. Optimum chitin yields were observed for most cultures at 28°C on Czapek's dox (CD) for 7 days. From the results we observed that; the production of chitin (by a dry weight method) ranged from 15.41 to 54.78 % of the isolate dry weight , the Fusarium KYM3 was the best producer of chitin of the isolates examined and Penicillium KYM6 was the lowest producer of chitin of the isolates examined.","PeriodicalId":21277,"journal":{"name":"Revista de Ciências Agrarias - Amazon Journal of Agricultural and Environmental Sciences","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89953051","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}

(Lepidoptera: Noctuidae). This study was carried out to monitor the resistance levels in field strain collected from Abou- Homos, El-Behira government to some insecticides in comparison with laboratory strain. In addition, ovicidal activity of the formulated tested insecticides against laboratory and field strain of CLW egg masses was determined. The activities of glutathione S transferases (GST) and total esterases were determined in both strains. The results revealed that 2 nd instar larvae of the field strain exhibited different levels of resistance to cypermethrin, chlorpyrifos, and methoxfenozide with resistance ratios (RR) 12.7, 48.0, and 13.8, respectively, while 2 nd instar larvae of field strain showed tolerance ratios 4.6 and 5.0 to chlorantraniliprole and chlorfluazuron, respectively. Fourth instar larvae exhibited high resistance levels to cypermethrin (120.8) and moderate resistance to chlorpyrifos (19.0). On the other hand, 4 th instar larvae of field strain showed tolerance ratios to chlorantraniliprole methoxfenozide and chlorfluazuron (3.3). Concerning the ovicidal and residual toxicity, cypermethrin, chlorpyrifos, chlorantraniliprole and chlorfluazuron at the recommended field rate achieved 95.3, 98.9, 93.3 and 96.8% mortality of treated eggs and neonates of the laboratory strain, respectively. The same treatments achieved 75.6, 70.0, 85.2 and 91.6%, respectively, for the egg masses of field strain. On the other hand, there is no significant difference between the ovicidal and residual toxicity of methoxfenozide against neonates of both strains. The field strain exerted elevated GST and esterases activity compared to the laboratory one. Therefore, monitoring of insecticide resistance is the first step for the resistance management programs.","PeriodicalId":21277,"journal":{"name":"Revista de Ciências Agrarias - Amazon Journal of Agricultural and Environmental Sciences","volume":"82 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80318251","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}
