The study spanned two consecutive years (2018 and 2019) and involved three planting dates: March, August, and October. Weekly thrips counts were recorded and compared across the different planting dates. According to the results, T. tabaci nymphs recorded maximum incidence in March sowing date and amounted to 118.5± 19.79 and 79.6± 18.99 individuals/ sample. While cucumber crop in October sowing date hosted the lowest number of T. tabaci nymphs amounted to 34.1± 7.38 and 29.5± 7.57 individuals/sample. Temperature and population of T. tabaci nymphs correlated significantly in August and October cucumber plantations.","PeriodicalId":13463,"journal":{"name":"Indian journal of entomology","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139323974","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}

On the basis of various field trials conducted neem insecticidal soap (NIS @ 2.5 %) and horticultural mineral oil (HP spray oil 2% of solution) were found effective against major pests. In case of severe infestation imidacloprid (17.8 SL) a.i. 0.075 % and cartap hydrochloride 4G @ 100g/ tree resulted in their efficient suppression. As such these treatments were incorporated in grower specific IPM modules evaluated for two years. Amongst the tested modules, integrated module (M1) followed by pesticide module (M3) were found most effective. However, for resource poor farmers and non-disruptive cultural module M1 and organic growers M2 could be alternatively practiced.

The growth and biochemical parameters of the three native isolates of B. bassiana (BTL1: OP271760, BTL2: OP290199 and PKDE: OP292066) were studied under different abiotic stress conditions viz., temperature, water stress, acidity and salinity.
