Abstract

The toxicity of some insecticides and biopesticides evaluated against first instar larvae of Spodoptera frugiperda (J.E. Smith) revealed that emamectin benzoate 5 SG was the most effective (LC50 value being 0.052 ppm) followed by chlorantraniliprole 18.5 SC (0.646 ppm), spinetoram 11.7 SC (0.930 ppm), novaluron 5.25 + emamectin benzoate 0.9 SC (1.418 ppm), chlorantraniliprole 9.3 + lambda cyhalothrin 4.6 ZC (1.594 ppm), azadirachtin (2.217 ppm), Bacillus thuringiensis (3.5 × 107 cfu/g/L) and Metarhizium anisopliae (1.8 × 108 cfu/g/L). The order of relative toxicity of insecticides based on LC50 values in the descending order over chlorantraniliprole + lambda cyhalothrin was emamectin benzoate > chlorantraniliprole > spinetoram > novaluron + emamectin benzoate.
