An experiment was conducted to observe the “Influence of abiotic factors on seasonal abundance of sucking insect-pests on brinjal” during kharif-2017 at Oilseed Research Station, Latur, Maharashtra. The incidence of sucking insect-pest viz., jassids and whitefly was observed from 31^st – 52^nd (July to December) standard meteorological week (SMW). The incidence of jassid reached to its peak (12.46 jassids/3 leaves) during 39^th SMW (second fortnight of September). While, the maximum population of whitefly observed during 40^th SMW (14.70 jassids/3 leaves) i.e. first week of October. The correlation studies between incidence of jassid and weather parameters showed significant positive correlation (r= 0.472) with maximum temperature while other parameters were found non-significant correlation with jassid. The incidence of whitefly showed significant positive correlation (r= 0.344) with maximum temperature, mean temperature and evening relative humidity.
