Summary

Studies was carried out to investigate population dynamics and the effect of abiotic factors on population dynamics of sucking insect pests of BT cotton whitefly (Bemisia tabaci) and jassid (Amrasca biguttula), under unprotected condition. The results of the field study revealed that the sucking pest (whiteflies and jassids) population were maximum at highest temperature. (11.68) of whiteflies per leaf was recorded at highest temperature (45 oC) and lowest humidity (30%). Similarly, the maximum population (3.53) of jassids per leaf was recorded at maximum temperature (45 oC) and lowest humidity (30%) on July 10th, 2017. The rainfall had slight impact on the population of whiteflies and Jassids. Simple correlation analysis revealed that maximum temperature showed significant positive effect and the minimum temperature showed negative effect on these pests. The relative humidity was non-significant effect, whereas precipitation was negative effect on all the sucking pests
