A field experiment was conducted at Agronomy Farm, College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Bikaner to study the effect of abiotic factors on the incidence of major sucking insect pests and their natural enemies associated with cluster bean, Cyamopsis tetragonoloba (Linn.) Taub. during kharif season 2015 and 2016. The invasion of major sucking insect pests, jassid, Empoasca motti Pruthi; whitefly, Bemisia tabaci (Genn) and aphid, Aphis craccivora Koch commenced in the second week of August (33rd standard meteorological week, SMW) during 2015 as well as 2016 and reached at their peak in the first and second week of September i.e., 37th and 38th SMW. The population of jassid at peak period was 14.80 &15.50 and that of whitefly was 15.85 & 17.20 per 3 leaves during 2015 and 2016 respectively. The population of aphid reached at the peak in first week of September (36th SMW) and it was 7.80 and 6.85 per 3 leaves in the respective years. There was significant negative correlation of the population of jassid (r=-0.65*) and whitefly (r= -0.63*) with relative humidity during 2015. The correlation of the population of aphid (r=0.55*) with relative humidity was significantly positive in 2016. The correlation of the population of jassid (r= 0.47*, 0.63*) and whitefly (r= 0.52*, 0.72*) with maximum temperature was significantly positive in 2015 and 2016, respectively. The correlation of the population of aphid (r=0.55*, 0.52*) with minimum temperature was significantly positive in 2015 and 2016, respectively. The population of Coccinella septempunctata L. had significant positive correlation with the population of jassid (r= 0.89*, 0.95**), whitefly (r= 0.78*, 0.96**) and aphid (r= 0.55*, 0.56*) during both the years. The population of Chrysoperla carnea showed significant positive correlation with the population of jassid (r= 0.66*, 0.85*) and whitefly (r= 0.53*, 0.91**) but non-significant with aphid C. carnea during both the years.
