Abstract:
A field experiment was conducted to seasonal incidence of major sucking insect pests of aphid, Aphis craccivora Koch, leafhopper, Empoasca fabae (Harris), whitefly, Bemisia tabaci (Genn.) on cowpea, Vigna unguiculata (Linn.) Walp. at Sri Karan Narendra College of Agriculture, Jobner, Rajasthan. Revealed that sucking insect pest population were commenced in the last week of July (30th standard meteorological week) and reached to a peak of 123.00 aphids/10 cm terminal shoot, 15.30 leafhoppers/ three leaves and 14.60 whiteflies/ three leaves on 18th August (33rd standard meteorological week), respectively. The population of aphid, leafhopper, and whitefly showed significant positive correlation r=0.743, r=0.717 and r=0.719, respectively, with maximum temperature. The population of ladybird beetle, Coccinella septempunctata Linn. started one week after initiation of sucking insect pests (31th Standard Meteorological Week) and reached to maximum 9.60/ five plants on 25th August (34th standard meteorological week). The ladybird beetle population showed positive significant correlation with the population of aphid (r=0.708), leafhopper (r=0.727) and whitefly (r=0.722).
