Abstract
A field experiment conducted during the kharif 2018 evaluated the seasonal incidence of insect pests of mungbean. The results revealed occurrence of major sucking insect pests viz., whitefly Bemisia tabaci (Genn.), leafhopper Empoasca kerri Pruthi, aphid Aphis craccivora Koch from vegetative stage to maturity stage. The lepidopterans viz., tobacco caterpillar Spodoptera litura (F.) and blue butterfly Lampides boeticus L., were observed from reproductive to maturity stage. Maximum incidence of B. tabaci was -at 9.70 nymphs and adults/ cage, E. kerri at 4.97 nymphs and adults/ plant, A. craccivora at 2.17 nymphs and adults/ plant, S. litura at 0.33 larvae/ plant and L. boeticus at 0.37 larvae/ plant and during the 39<sup>th</sup> standard week. Incidence of B. tabaci, A. craccivora, S. litura and L. boeticus showed significant positive correlation with maximum temperature, (r=0.79, 0.76, 0.82 and 0.85, respectively; B. tabaci with rainfall and S. litura with evening relative humidity showed a significant negative correlation (r=-0.76, -0.81, respectively).
