 ABSTRACT

Armyworm, Spodoptera litura is major threat to agricultural and horticultural crops all over the world. Biological parameters of Armyworm, Spodoptera litura and toxicity of different insecticides against 2nd instar larvae on cabbage were conducted in Faisalabad during 2019. The total developmental period from egg to adult was 31 days. The incubation period and percent viability of eggs on cabbage was 3 days and 90%, respectively. The weight of full-grown larva and pupa was 1000 and 300 mg, respectively.  The highest adult emergence was recorded 90% on cabbage. Among tested insecticides, emamectin benzoate was found more toxic followed by lufenuron and chlorpyrifos. The significant difference was recorded in lethal time and lethal concentration values. LT50 values revealed that chlorpyrifos was recorded more effective followed by emamectin benzoate and lufenuron and required less time to kill 50% 2nd instar larvae. The study informations will be fruitful in pest management.

Keywords: Spodoptera litura, Biology, Cabbage, Caterpillar, Insecticide efficacy, Time and dose mortality.
