The study was carried out to find out the seasonal abundance of major sucking insect pests and their natural enemies in brinjal, Solanum melongena L. The population of jassid, Amrasca biguttula biguttula (Ishida) and whitefly, Bemisia tabaci (Gennadius.) on brinjal initiated in 33" standard meteorological week, whereas C. septempunctata initiated in the 34" standard meteorological week when maximum and minimum temperature was 31.9°C and 24.2°C, respectively with 76.5 per cent relative humidity. The population build up gradually and arrived at peak on 39th standard meteorological week 45.2 (jassids) and 52.4 (whiteflies) per three leaves. The correlation matrix indicated a significant correlation of jassid and whitefly with both the maximum (r = 0.83 and 0.81, respectively) and minimum temperature (r = 0.57 and 0.67, respectively) and both the whitefly and jassid population recorded a positive and significant association with the population of C. septempunctata (r = 0.68 and 0.67, respectively).
