Bees take the part of a vital role in the maintenance of biodiversity, and in food and fibre production. Now a day, they are confronting risk due to non-selective use of pesticides. Laboratory study was conducted at Department of Agricultural Entomology, UAS, GKVK, Bengaluru to assess the risk of novel insecticide, cyantraniliprole to honey bee, Apis cerana indica F. through standard feeding technique. Diamide insecticide, cyantraniliprole was assessed at two different doses (300 ng/ bee and 600 ng/ bee). The cumulative mortality of honey bees was recorded at 4, 8, 18, 24 and 48 h after the treatment imposition. The tested insecticide witnessed mortality of honey bees in the study. Cyantraniliprole registered per cent cumulative mortality of 54 with the dose of 300 ng/bee at 24 h after treatment and 48 per cent cumulative mortality with the dose of 600 ng/bee at 8 h exposure. Results further demonstrated that, mortality of bees was maximum at higher doses of insecticide.
