Abstract: Tomato is most popular and widely grown vegetable in the world and suffering from both biotic and abiotic stresses. Aphis gossypii, Bemisia tabaci, Thrips tabaci, Liriomyza trifolii, Spodoptera liura and Helicoverpa armigera are the major important insects and causing severe losses under favorable weather condition. The proposed research study was conducted during 2016-17 at Central Research Farm, BCKV. On Tomato (Moula F1 hybrid) on Comparison of population dynamics of important insect pests and their relationship with weather parameters in open field and cover cultivation. The results revealed that whitefly, aphid and leaf miner were most important insects damaging tomato during November to March in this region under open conditions whereas leaf miner and whitefly in poly house. The peak population of these pests was observed during 8 and 9 SMW under both conditions. Pest population and density fluctuation is very low in poly house when compared to open condition expect the leaf miner whose population was high in poly house. Weather relations revealed that Pests under open condition showed greater association with weather variables than in poly house. Whereas canopy temperature, light intensity showed greater degree of association with pests in compression with air temperature and BSH recorded.
