Description and Damage: Brown stink bug nymphs are pale yellow-green to tan with dark brown spots in the center of the back. Adults are 3 /4 inch long and brown with a yellow or light green underside.
The brown stink bug has a rounded lateral angle on the shoulders. The similar spined soldier bug (Podisus maculiventris) has pointed shoulders and is a predator, not a pest of sorghum.
Stink bugs feed mainly on kernels and cause the most damage during early kernel development.
