Field experiments were conducted at two different geographical regions viz., tropical region (Naraseepuram village, Coimbatore) and temperate region (Kookal village, Kotagiri, The Nilgiris) in summer and winter season’s to assess the bioefficacy of insecticides used against Diamondbackmoth (DBM), Plutella xylostella and their potential impact on natural enemies in cauliflower. The results revealed that the diamide insecticides like cyantraniliprole 10.26 OD @ 60 g a.i ha-1, chlorantraniliprole 18.50 SC @ 10 g a.i ha-1 and flubendiamide 20 WG @ 18.24 g a.i ha-1 registered more than 95 percent population reduction over untreated control followed by emamectin benzoate 5 SG @ 10 g a.i ha-1 and thiodicarb 75 WP @ 750 g a.i ha-1. Quinalphos 25 EC @ 500 g a.i ha-1and chlorpyriphos 20 EC @ 400 g a.i ha-1 were observed as least effective among the treated insecticides. The diamide insecticides recorded considerably less toxic effect on the natural enemies, especially spiders and coccinellids. Population reduction of natural enemies was noticed immediately after insecticide spray but it gradually increased and was recorded on par with the control population. Hence, cyantraniliprole 10.26 OD @ 60 g a.i ha-1, chlorantraniliprole 18.50 SC @ 10 g a.i ha-1 and flubendiamide 20 WG @ 18.24 g a.i ha-1 can be used as potential component in the integrated pest management against DBM in cole crops.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
