Abstract

Study on seasonal incidence of Aphis gossypii infecting chilli was carried out at College Farm, UAS Dharwad, during rabi 2018-19. The crop was grown in a plot size 20x20 m with spacing of 60x60 cm. The aphid population was recorded on chilli from 6th Week After Transplanting (WAT) (2.37 aphids/leaf) and reached to a peak level of 32.20 aphids/leaf during 10th WAT. Later it followed decreasing trend and attained least incidence of 6.50 aphids/leaf at 14th WAT. Among the two natural enemies investigated, ladybird beetle showed significant positive correlation (r=0.560) with aphid incidence whereas, non-significant positive association noticed with green lacewing population (r= 0.429).
