Green chilli is one of the most popular vegetable cum spice crop widely cultivated in different parts of West Bengal subject to suffer with lots of biotic stress among which fruit borer (Spodoptera litura) is now gaining importance as one of the major constraints in green chilli production. Highly polyphagous and voracious nature makes it difficult to manage efficiently. New generation insecticides have a good role regarding managing the crops with less toxicity. To obtain a conclusion about efficacy of some new chemistry (spinosyn, abamectin derivative, diamide) against this pest a field experiments were conducted to observe, the efficacy of some bio rational insecticides (spinosad, emamectin benzoate, flubendiamide) for the management of Spodoptera litura on chilli during the rabi season of 2013 and 2014. Results showed that flubendiamide 20% WG @ 60 g a.i. ha-1 were found to be superior over other treatments against Spodoptera on chilli, with 95.50% mean reduction after two spraying, lowest fruit infestation (1.07%), 92.43% protection over control and highest marketable fruit yield (18.19 q ha-1). Emamectin benzoate was recorded as next effective insecticide (1.96% fruit infestation by borer and 86.21% protection over control) which is closely followed by flubendiamide @ 50 g a.i. ha-1 and spinosad (85.61% and 85.03% protection over control plot).
