abstract
The present study was carried out during the period of November 2016 to April 2017 at Agriculture farm, Palli Siksha Bhavana (Institute of Agriculture), Visva-Bharati, at Sriniketan. Influence of weather parameters on the seasonal incidence of insect pests of okra was observed during rabi season. In okra the incidence of A. gossypii, was maximum during February (8^th MSW) and minimum during March (10^th MSW). The incidence of B. tabaci was maximum during February (6^th MSW) and minimum during March (9^th MSW). The incidence of A. biguttula biguttula, was maximum during March (12^th MSW) and minimum during April (14^th MSW). Leafhopper had significant positive correlation with maximum temperature when correlated with Actual week weather data. The incidence of Tetranychus spp., was maximum during March (12^th MSW) and minimum during April (14^th MSW). The incidence of E. vitella/ insulana fruit infestation was maximum during March (11^th MSW) and minimum during April (14^th MSW). The coefficient of determination (R²) for aphid, whitefly, leafhopper, and mite and fruit infestation was 0.671, 0.576, 0.754, 0.752 and 0.743, respectively. The statistically significant values indicated that occurrence of insect pests population was due to the prevailing ecological conditions.
