False Chinch Bugs in Sorghum
Tom A. Royer, Extension Entomologist
I’m starting to receive reports of false chinch bug infesting sorghum heads. As sorghum begins to head, it is important to make sure your crop is not being damaged by this insect. False chinch bug nymphs are ash-gray with brown-white mottling on the back and red mottling on the abdomen. Adults measure about 1/8 inch long, are dirty gray, with brown or black markings. This insect injures plants by sucking the liquid in developing seeds when they are in the milk stage. It has a life span of about 40 days (from egg hatch through adult).
