Abstract:
A field experiment was conducted to seasonal abundance of major sucking insect pests of leafhopper, Empoasca motti (Pruthi.), whitefly, Bemisia tabaci (Genn.) and thrips, Caliothrips indicus (Bagnall) on moth bean, Vigna aconitifolia (Jacq.) Marechal. The incidence of leafhopper reached peak population of 7.84 leafhopper/ three leaves. The incidence of whitefly commenced in the first week of August of 32^nd standard meteorological week of which gradually increased and reached its peak of 11.40 whitefly/ three leaves of moth bean in the first week of September of 36^th standard meteorological week. The incidence of thrips reached peak population of 9.48 thrips/ three leaves in the first week of September of 36^th standard meteorological week, thereafter, the population of thrips declined on moth bean crop. The relative humidity showed positive significant correlation with leafhopper (r= 0.69), whitefly (r= 0.66) and thrips (r= 0.67) population whereas, maximum temperature, minimum temperature and rainfall showed non-significant correlation with leafhopper population.
