Seasonal occurrence of aphid, Aphis gossypii Glover and its natural enemies on Chilli (Capsicum annuum L.)

The aphid population was initiated from 6^th week after transplanting and reached to a peak level 9.1 aphid/leaf during 10^th WAT. Correlation coefficient values for aphid incidence and weather parameters showed that maximum, minimum temperatures, mean temperature, morning and evening relative humidity, mean relative humidity, wind velocity and sunshine hours had non-significant negative influence on aphid population. Green lacewing and lady bird beetle had highly significant negative correlated with maximum, minimum temperatures and average temperature. The spider highly significant negatively correlated with maximum, minimum temperatures, average temperature and morning relative humidity, while average relative humidity had significantly negative correlated with lady bird beetle. The remaining weather parameters did not show any significance. Green lace wing highly significant positively association with aphid, lady bird beetle showed highly significant positively correlated with aphid and spider, found highly significant positively correlated with aphid.
