The present study compares the insecticidal activity of Sesbania grandiflora extracts in hexane, ethyl acetate, and ethanol obtained from two extraction methods: Soxhlet and cold maceration against P. xylostella. Soxhlet extraction by all the solvents showed a distinct effect on larval mortality, adult emergence, and the growth and development of second-instar larvae than cold maceration extraction. Soxhlet ethanolic extract at 5% had significantly better insecticidal activity than cold maceration, with complete larval mortality. The antifeedant index was also higher in ethanol extract, followed by ethyl acetate and hexane extract. However, there was no significant variation in the developmental period. Thus, Soxhlet ethanolic extract of S. grandiflora is concluded to have a promising insecticidal activity on P. xylostella.","PeriodicalId":13463,"journal":{"name":"Indian journal of entomology","volume":"732 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140465668","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}

For molecular identification, the DNA was first isolated, amplified by using PCR followed by sequencing the ITS region. A phylogenetic tree was also constructed based on the data obtained from sequencing to trace the evolutionary history of the isolated fungus. The fungal species was identified as Beauveria bassiana with 98.6% sequence similarity with already documented B. bassiana strains. The toxicity of the isolated fungus was also evaluated against A. assamensis larvae.

A high % of methyl-branched alkanes were identified in all inversion (2LA, 3LA and 2LA+3LA) and inversion-free strains followed by linear alkanes and alkenes. The present work unfolds the significant patterns of variations in the isomeric forms of methylated alkanes between the inversion and inversion free strains (F-46.6; df-3, p 0.005), and non-significant between the sex (F-2.14; df-1, p 0.2394). But in linear alkanes shows significant variation between the inversion strains (F-30.49; df-3, p 0.009) and between the male and female (F-115.45; df-1, p 0.001) was observed. In particular there is a significant correlation between the chromosomal inversion and synthesis of CHCs in D. ananassae. Unique blend of CHCs in Drosophila performs dual role as desiccation resistance and act as chemical signalling molecule. Linear alkanes are majorly involved in desiccation resistance but in methyl- branched CHCs length variation is a key determinant of desiccation resistance. Presence of longer methyl- branched alkanes and higher desiccation resistance, shorter the carbon chain length act as a signalling molecules. The current study revealed the influence of chromosomal inversion on the cuticular hydrocarbon profile in D. ananassae.","PeriodicalId":13463,"journal":{"name":"Indian journal of entomology","volume":"93 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140465579","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}
