abstract
Studies were conducted on incidence of Aphis gossypii on okra under field conditions at faculty of agriculture Shere Kashmir University of Agriculture Sciences and Technology during 2018. The incidence of aphids commenced from 29^th standard week and was lowest (3.30 aphids/3 leaves). The aphid count gradually increased and reached its peak in 32^nd SW (47.28 aphids/3leaves) thereafter it declined and was again minimum during 40^th SW (5.19 aphids/3 leaves). The study of relation of weather parameters on incidence of aphids revealed 47 per cent of variability of aphid counts is explained by weather factors. Further, a significant and positive correlation was found between the aphid count and maximum temperature (r= 0.331), minimum temperature (r= 0.020) and minimum relative humidity (r= 0.266), however negative correlation was found between aphid count and maximum relative humidity (r=-0.323) and rainfall (r=-0.249). The contribution of weather factors on A. gossypii population was 47 per cent (R²=0.47).
