The present experiment entitled Studies on population dynamics of sucking pests complex of chilli and their relation with environmental factors was carried out in Insectary, Department of Entomology, CSAUA&T, Kanpur in kharif season 2018-2019. An experiment is conducted to find out the seasonal abundance of sucking pest complex of chilli. The presence of aphid, whitefly, and mites were recorded from the vegetative to maturity stage of the crop. Aphid, whitefly and mites were found to damage the crop moderately. First appearance of aphids were observed on 33rd standard week and reached at its peak during 37th standard week. The aphid population showed positive significant relation with maximum temperature and positive non significant relation with the minimum temperature, minimum relative humidity. Maximum relative humidity and rainfall are negatively non significant with aphid population. The occurrence of thrips on 35th standard week and reached to peak on 44th standard week. Maximum temperature showed non- significant positive correlation with thrips population. Minimum temperature have non-significant negative correlation. Remaining maximum and minimum relative humidity, rainfall showed negative correlation but statistically significant. Chilli mite was first appeared on 36th standard week and it’s at peak on 47th standard week. Maximum and minimum temperature, maximum and minimum relative humidity, rainfall are negatively correlated to the mite population. Maximum temperature is non-significant while all other parameters are statistically significant.
