Grain legumes are the important source of dietary protein in tropical regions and insect pests are the major biotic constraints in the production of the grain legumes throughout the country. About 150 species of insects are known to attack pulse crops in India. Among the insect pests, the sucking pests like aphid, Aphis craccivora Koch; jassid, Empoasca kerri Pruthi; whitefly, Bemisia tabaci Gennadius, thrips,Thrips palmi Karny and flower thrips, Megalurothrips usitatus Bagnall are known to cause significant damage to the pulse crops and also indirectly acting as a vectors in transmitting the deadly diseases resulting in severe loss in grain yields of the legume crops. The present review highlights the losses caused by the sucking pests and critically review the literature generated on the bio efficacy of conventional and novel groups of chemical insecticides for the management of sucking pests infesting grain legumes at different locations in India.

A field experiment was conducted to determine the efficacy of different insecticides against sucking pests viz., thrips, Caliothrips indicus Bangall and whitefly Bemisia tabaci Gennadius, infesting blackgram in North coastal Andhrapradesh at Agricultural College, Naira during rabi 2017-2018.The experimental results revealed that all the treatments showed significant differences in reducing the population of sucking pests over untreated check. Among the tested insecticides, thiacloprid 21.7 SC @ 0.0325% was found to be highly effective against thrips by reducing74.80 per cent thrips population followed by acetamiprid 4 % + fipronil 4% @ 2ml l-1 with 70.81 per cent over untreated control, whereas flonicamid 50 WG @ 0.0325% was very effective against the population of whitefly byreducing 72.19 per cent and lowest per cent disease incidence (17.66%) followed by acetamiprid 4% + fipronil 4% @ 2ml l-1 (64.94%) and thiamethoxam 25 WG @ 0.005% (62.21%) which were on par with each other over control.
