Abstract
The present investigation was carried out at AAU-Zonal Research Station, Diphu, Assam to study the biology of fall army worm and to evaluate various newer class of insecticides against Fall army worm, Spodoptera frugiperda in maize crop. The study revealed that the average mean of incubation period was found to be 4.3±0.03. Total developmental period from egg to adult was found to be 30-45 days with an average mean of 36.4±1.34.The egg laying capacity of the female moth varied 100-450 eggs with an average of 280.9±1.34. The efficacy study of newer class of insecticides revealed that all the treatments were effective in controlling the pest population with the highest reduction percentage in the treatment with Chlorantraniliprole 18.5 SC (82.47) and Pyridalyl 10% EC (82.05) 10 DAT. The lowest was found in Azadirachtin 1500ppm (55.37) 10 DAT. However, a non chemical intervention during the initial stage of the pest occurance has been found to bring down the pest population in substiantial amount.
