In India among all pulse crops black gram, Bengal gram and cowpea are frequently grown as short-duration crops in Kharif followed by rabi crops like jowar, wheat, Bengal gram, and safflower. It is drought-resistant and suitable for dryland farming. The crop plays an important role in sustaining soil fertility by improving soil physical properties and fixing atmospheric nitrogen. The low yield of green grams in our country may be attributed to a wide variety of factors, among which the ravage of insect pests is paramount.

A number of insect pests belonging to different orders have been recorded on green grams from various parts of the world. Most pests of a green gram are cutworm,  aphids, thrips, Bihar hairy caterpillar, tobacco caterpillar, gram caterpillar,  leaf-eating caterpillar and pod borer. are some insects which affect quality and quantity.  Spray insecticides like emamectin benzoate 5 SG at 0.25ml/l or spinosad 45 SC at 0.25ml/liter or lambda-cyhalothrin 5 EC 1.00ml/liter, dimethoate 30EC or chlorpyriphos 20 EC at 2ml/liter for effective management of the pest.
