Toxicity of New Molecules of Insecticides against Honeybee, Apis mellifera L.

The newer molecules of insecticides were tested for their safety against honeybee, Apis mellifera L. Commercial grade formulations of newer insecticide molecules viz. Chlorantraniliprole 18.5SC, Flubendiamide 20WG, Emamectin benzoate 5SG,Spinosad 45SC, Indoxacarb 14.5SC, Thiodicarb 75WP, Fipronil 5SC, Fenvalerate 20EC, Acetamiprid 20SP, Thiacloprid 21.7SC, Imidacloprid 17.8SL, Clothianidin 50WDG, Buprofezin 25SC, Acephate 75SP and Cartap hydrochloride 50SP were used in the study. Considering the cumulative mortality at 24 hours after treatment, buprofezin 25SC (250 g a.i./ha), chlorantraniliprole 18.5SC (30 g a.i./ha) and flubendiamide 20WG (75 g a.i./ha) were found to be safe as they recorded 55.53, 77.76 and 88.86 per cent mortality in comparison to 100.00 per cent mortality in the remaining treatments
