Common chinch bugs in sorghum.pdf

The common chinch bug (Blissus leucopterus) is a serious pest of sorghum, especially in warm and dry conditions. Both nymphs and adults suck sap from the base of sorghum plants, leading to yellowing, wilting, and even plant death in severe cases. Damage is more noticeable during drought stress. Chinch bugs usually congregate at the base of plants and move upward as the plant grows. Management includes early planting, crop rotation, destruction of crop residues, and the use of resistant varieties. Insecticides may be applied if infestations are heavy and economic thresholds are crossed.
