Abstract:

This study was conducted to evaluate the third instar larvae of Helicoverpa armigera mortality percentile. Different kind of neem products such as leaf extract, neem seed kernel extract and neem oil were used alone and in combination at the concentrations of 5 percentile of each treatment. There was a significant difference in the mortality percentile and all the treatments were effective. The third instar larvae were more susceptible to the neem products and after 72 hours the maximum mortality 39.98 percentile was observed in the treatment where the neem leaf extract + neem oil was used third instar larvae of H. armigera at the exposure. In different chemical insecticides (Chlorpyriphos 40 EC, Lamda cyclothrin 5EC, Cypermethrin 25 EC, Idoxacarb 14.5 SC) of 200 ppm were against third instar larvae of Helicoverpa armigera mortality percentile. Results showed Indoxacarb14.5 SC insecticide was very effective for third instar larvae at 200 ppm concentration which gave maximum mortality 81.63 percentile after 72 hours. Results reveal that the neem leaf extract + neem oil and Indoxacarb can be used in the integrated pest management programme for all lepidopteron insect affected crops.
