Abstract
In this study, the population dynamics and bio-ecology of the Diaphania indica (Saunders) (Lepidoptera: Crambidae) have been investigated. The abundance of D. indica was recorded throughout the year between 2018 and 2019 indicating an overlapping of generations. We found that abundance/incidence between June - July was maximum compared to early summer and winter. The population density and weather parameters i.e., relative humidity was positively correlated and temperature was negatively correlated with the incidence of D. indica. The regression model also supported the relationship between the pest population buildup and weather factors. In addition, we found Apanteles taragamae Viereck and Phanerotoma sp. (both Hymenoptera: Braconidae) were the key mortality factors of D. indica as parasitoids. The present investigation helps to develop integrated pest management practices for D. indica.
