Seasonal incidence of chilli thrips (Scirtothrips dorsalis Linn.) on chilli & its correlation with different abiotic factors

Abstract

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 (47th SMW) and reached to its peak population (20.2 thrips/plant) during the second week of April (15th 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.
