As major one while its minor pests as aphid (Aphis gossypii Glover), brinjal leaf roller (Eublemma olivacea Walker), jassid (Hishimonas phycitis) etc. Six nitrogenous fertilizer doses (0, 20, 40, 60, 80 and 100 kg ha-1) were responded against sucking pests (jassid, white fly and mite) infesting brinjal. The mean pests population showed that the fertilizer dose 0 and 100 kg ha-1 nitrogen ha-1 minimum and maximum population, respectively. The rest of the fertilizer doses harboured moderate level of pests population. The orders of different doses in increasing trend of population of pests were: 0, 20, 40, 60, 80 and 100 kg nitrogen ha-1.
