abstract
Laboratory studies were conducted to assess the safety of flubendiamide 20 WG on non-target organisms viz., Egg parasitoid, Trichogramma chilonis, Predator, Chrysoperla zastrowii silemi and four different species of honey bees. Flubendiamide 20 WG at higher doses (70 and 60 g a.i. ha^-1) was better than stand alone products viz., quinalphos 25 EC, novaluron 10 EC and emamectin benzoate 5 SG in terms of toxicity to non-target organisms. The hatchability and parasatisation of T. chilonis was not affected by flubendiamide 20 WG at 70 and 60 g a.i. ha^-1 as they recorded more than 65 per cent of hatchability and parasitisation. Flubendiamide 20 WG 70 and 60 g a.i. ha^-1 was found safer to predator C. zastrowi sillemi as the hatchability per cent was above 50 per cent and grub mortality was below 50 per cent. The contact toxicity of flubendiamide 20 WG to honey bees viz., Apis cerana indica F., A. florea F., A. dorsata F. and Trigona iridipennis at 70, 60, 50 and 40 g a.i. ha^-1 recorded the lowest mortality (<40%) when compared to standard checks viz., quinalphos 25 EC, novaluron 10 EC and emamectin benzoate 5 SG at 24 HAT.
