Abstract:

Sorghum seedlings were initially stunted when exposed to chinch bug, Blissus leucopterus leucopterus (Say) for 7 days. Forage variety Early Sumac incurred 28 and 61% plant mortality by 5 and 10 bugs/plant but final yields of surviving plants transplanted to the field did not differ significantly from controls. All plants of grain hybrid DeKalb DK-61 survived and visually recovered but grain yields were reduced 28 and 68%.
