CONT: Host: Chinch bugs attack a variety of forage, lawn, and wild grasses. The principal crop plants damaged are wheat, corn, sorghum, oats, etc. Symptoms: The chinch bug pierces the plant with its moth parts and sucks out the plant sap. This feeding prevents normal growth and results in dwarfing, lodging, and yield reduction. Severe infestations during early development may cause plants to wilt and die prematurely. Most injury is caused by the six nymphal instars.
OBS: [A] small (about 1/8th inch (3-4 mm)) North American insect in the order Hemiptera and family Lygaeidae.
