Sorghum shoot fly, & x28;Atherigona soccata& x29;, is a particularly nasty pest of sorghum in Asia, Africa, and the Mediterranean area. Females lay single cigar-shaped eggs on the undersides of leaves at the 1- to 7-leaf stage. The eggs hatch after only a day or two of incubation, and the larvae cut the growing point of the leaf, resulting in wilting and drying. These leaves, known as & x27;deadhearts& x27;, are easily plucked. When a & x22;dead heart& x22; is plucked, it releases an obnoxious odor.
