It is one of the most common parasitic microbes and is possibly the most common reproductive parasite in the biosphere. The bacterium is best known for its ability to manipulate host reproductive biology where it can induce cytoplasmic incompatibility, parthenogenesis, feminization and male-killing. In the present study, onion thrips (Thrips tabaci Lindeman) were collected from 9 locations in India along with melon thrips (Thrips palmi Karny) and chilli thrips (Scirtothrips dorsalis). From the molecular level detection by using 16s rDNA, the Wolbachia infection has been detected in the onion thrips collected from 6 locations out of 9. Melon thrips and chilli thrips samples were also found to be infected by Wolbachia. The phylogenetic analysis revealed that all detected Wolbachia samples showed that all were distantly related to the previously known Wolbachia samples.","PeriodicalId":13463,"journal":{"name":"Indian journal of entomology","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139323975","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}

Essentially this protocol consist of three steps which are: (1) Temperature incubation of test insects: includes three hour starvation period and temperature treatment of B. tabaci; (2) Preparatory steps of leaf-dip bioassay: suggests use of agar cube method (reduces agar usage by 70%) to maintain green and turgid test leaves during post-exposure period of bioassay; (3) Release of temperature treated insects and mortality counting: test insect release, securing petri plates, recording observations, etc. all are deliberated in detail.

The wheat varieties were premeditated for their physical components through correlation analysis and the level of influence on insect preference and development was determined. The variety DBW303 which had a high median development period, low adult emergence and susceptible index was found to be resistant. Similarly, the variety PBW373 which recorded a low median developmental period with higher adult emergence, and susceptible index, was found to be susceptible. Among the physical traits, varieties with grain hardness exhibited a negative relationship with progeny development and thus conferred resistance.","PeriodicalId":13463,"journal":{"name":"Indian journal of entomology","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139324015","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 new DII was developed based on observable symptoms and the intensity of damage, such as the number and diameter of feeding lesions, and TMB-infested areas on cocoa pods. Statistical techniques, including linear correlation and regression, have been employed to develop an appropriate DII. The study reveals a significant correlation between the mean of total feeding lesions (Xn) and feeding lesions present on the middle portion (Xm) of cocoa pods, surpassing other combinations and indicating a strong relationship between these variables. The damage intensity was estimated using a linear regression approach resulting equation, Xn = 1.79 + 0.25Mn (R2 = 0.989), offers a quantified means of estimating damage intensity on cocoa pods. Analysis of infestation and the regression equation establishes DII values between 1.79 to 76.79. This novel index suggests that the minimum sample size of 90 pods is required for estimating a population with a 95% confidence level to arrive at precision decision making of TMB damage on cocoa pods. The novel damage intensity index and the calculated sample size from this investigation could be useful in conducting various studies, such as germplasm screening, breeding for pest resistance, evaluating the effectiveness of new insecticides, and formulating an IPM package for managing Helopeltis spp. in cocoa.","PeriodicalId":13463,"journal":{"name":"Indian journal of entomology","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139323832","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}

As the pest causes significant damage in the vegetative stages, seed treatment can also be an option. In the present study, seed treatment has been evaluated for its efficacy in comparison with spray in maize. The results suggested that chlorantraniliprole 62.5FS was more effective than presently used seed treatment with cyantraniliprole. In case of foliar spray, spinetoram 11.7SC along with chlorantraniliprole 18.5SC and emamectin benzoate 5SG were found effective. As seed treatment is easy to practice and economical, seed treatment with diamides, particularly chlorantraniliprole 62.5FS might provide a better alternative to foliar sprays during early crop stage. Hence, an integrated strategy involving seed treatment in combination with need-based foliar spray at later crop stages may make management of S. frugiperda more efficient.","PeriodicalId":13463,"journal":{"name":"Indian journal of entomology","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139323850","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}
