abstract
The lethal effects of biorational insecticides (methoxyfenozide (Runner 240 SC), spinosad (Tracer® 480 SC), emamectin benzoate (Logo 2.15%EC), indoxacarb (Avaunt15.8% EC) and lufenuron (Match 5% EC) as well one Control treatment against different life stages of Spodoptera litura were examined by Leaf Dip Bioassay method. The least possible mortality was caused by lufenuron (Match 5% EC) (18.4%) while highest mortality level was observed in (methoxyfenozide (Runner 240 SC) treatment (25%), so the highly toxic insecticide against the Spodoptera litura is methoxyfenozide at its higher concentration after 48 hours. The insecticides with moderate toxicity were spinosad (Tracer® 480 SC), indoxacarb (Avaunt15.8% EC) and emamectin benzoate (Logo 2.15%EC). Order of insecticides toxicity on the basis of mortality was methoxyfenozide > spinosad > indoxacarb > emamectin > lufenuron.
