An attempt was made to assess toxicity of insecticides against Spodoptera litura (Fab.). Indoxacarb at 24 h was 66.32 times more toxic than cartap hydrochloride at LC50 value. The relative toxicity ratio (RTR) of novel molecules at LC50 value in comparison to cartap hydrochloride at 24h and 48h were: indoxacarb (66.32, 82.5) > flubendiamide (11.45, 49.5) and at 72h the values were flubendiamide (118.33) > indoxacarb (71). LC50 values of cartap hydrochloride, flubendiamide and indoxacarb were 0.126%; 0.011%; and 0.0019%, respectively at 24h. Indoxacarb and flubendiamide with low LC50 values demonstrated higher toxicity against S.litura than cartap hydrochloride.
