Abstract:
Bio efficacy of different doses of Emamectin benzoate (0.001, 0.002 and 0.003 per cent), Indoxacarb (0.001, 0.002 and 0.003 per cent) and Rynaxypyr (0.001, 0.002 and 0.003 per cent) were evaluated by dipping of brood lac in different insecticidal formulations for 5, 10 and 15 minute time period against the predator of lac insect Eublemma amabilis in aghani lac crop in host plant Flemingia semialata at DKS CARS, Bhatapara, Chhattisgarh during 2019. Overall impact of different doses of insecticides, Emamectin benzoate @ 0.003 per cent at 15 minute time period was found very much effective in suppression the population of lac insect predator Eublemma amabilis Moore over control with minimum 0.66 numbers insect per 30 cm lac stick with 92.07 per cent reduction. Treatment of broodlac in insecticidal formulations for 5, 10 and 15 min durations exerted significant reduction in the population of lepidopteron predators, Eublemma amabilis Moore (Noctuidae).
