Population dynamics of major sucking pests on chilli and its relationship with weather factors

A field experiment was conducted at College of Agriculture, SKRAU, Bikaner to study the seasonal incidence of major sucking pests of chilli and its correlation with abiotic factors. The results revealed that the incidence of thrips on chilli started in first week of March and its peak was in third week of May. The attack of whitefly started started in the third week of March and its peak was recorded during second week of May. Jassid population increased gradually reaching the peak in last week of July. The population of mite started increasing from first week of March and reached peak in fourth week of April, while aphid reached its peak in third week of May. The occurrence of higher temperature showed significant positive correlation with thrips and whitefly while relative humidity and rainfall showed negative correlation. There was significant-positive correlation between minimum temperature and relative humidity in regard to jassid population while rainfall showed positive correlation.
