The relative toxicity of ten insecticides and three ready to use combination products, used for cotton insect pest management were assessed against the green lace wing, Chrysoperla zastrowi sillemi (Esben-Peterson) in the laboratory, Department of Agricultural Entomology, N. M. College of Agriculture, Navsari Agricultural University, Navsari during 2014. Amongst tested insecticides, buprofezin 25 SC @ 0.05% and fipronil 5 SC @ 0.02% were categorized as slightly harmful; clothianidin 50 WP @ 0.005%, diafenthiuron 50 WP @ 0.06%, imidacloprid 70 WG @ 0.005% and flonicamid 50 WDG @ 0.015% as moderately harmful and bifenthrin 10 EC @ 0.016%, lamda-cyhalothrin 5 EC @ 0.005%, methyl parathion 50 EC @ 0.1%, thiacloprid 21.7 SC @ 0.03%, chloropyriphos 50% + cypermethrin 5% EC @ 0.11, acephate 50% + imidachloprid 1.8% SP @ 0.103% and deltamethrin 1% + triazophos 35% EC @ 0.092% as harmful insecticides to the second instars larvae of C. zastrowi sillemi when assessed through thin film technique. While assessing relative toxicity through food contamination technique against the adults of C. zastrowi sillemi, buprofezin 25 SC @ 0.05% was categorized as harmless; bifenthrin 10 EC @ 0.016%, clothianidin 50 WP @ 0.005%, diafenthiuron 50 WP @ 0.06%, fipronil 5 SC @ 0.02%, imidacloprid 70 WG @ 0.005%, flonicamid 50 WDG @ 0.015% and thiacloprid 21.7 SC @ 0.03% as slightly harmful; lamda-cyhalothrin 5 EC @ 0.005%, acephate 50% + imidachloprid 1.8% SP @0.103% and chloropyriphos 50% + cypermethrin 5% EC @ 0.11% as moderately harmful and methyl parathion 50 EC @ 0.1% and deltamethrin 1% + triazophos 35% EC @ 0.092% as harmful insecticides.
