520			_aLaboratory experiments have been conducted to determine the lethal effects of Spinosad and Azadirachtin on the cotton leafworm, Spodoptera littoralis (Boisduval) (Lepidoptera: Noctuidae) larvae by a diet incorporation bioassay. Newly molted third instar larvae were exposed through ingestion to different concentrations. Larval mortality of S. littoralis increased with the concentration resulting a LC₅₀ values of 1.38 µg/ml and 0.14 µg/ml for, Spinosad and Azadirachtin respectively, the mortality times decreased with the concentration Increase. Sublethal effects were studied by treating of third instar larvae with a concentration equivalent to the respective LC₅₀. Both insecticides significantly increased larval development period from treatment until pupation, but the effect of Azadirachtin was greater than pinosad.
