The experiment was carried out at horticultural research farm of BTC CARS, Bilaspur during Rabi 2019-20. The outcomes revealed that the seasonal incidence of thrips (Scirtothrips dorsalis Linn.) on chilli crop was first noticed on fourth week of November 2019 (47^th SMW) and reached to its peak population (20.2 thrips/plant) during the second week of April (15^th SMW). The results revealed that the significant positive correlation with maximum (r = 0.689), minimum temperature (r = 0.690) and sunshine hours (r = 0.414) while significant negative correlation with morning relative humidity (r = -0.645) was observed with the thrips population.
