Stink bugs, including the southern green stink bug, Nezara viridula (L.), and the brown stink bug, Euschistus servus (Say), are responsible for losses of millions of dollars in reduced yields and costs of control on major vegetable and agronomic crops. Indeed, total losses for stink bugs during 2008 were estimated at $4.1 million for cotton, Gossypium hirsutum L., in the U.S (Williams 2009, http://www.entomology.msstate.edu/resources/tips/cotton-losses/data/2008/2008loss.html).

Sorghum, Sorghum bicolor (L.) Moench, has been shown to be an effective trap crop for N. viridula in cotton in farmscapes in which cotton is adjacent to corn, Zea mays L., and peanut, Arachis hypogaea L., in Georgia (Tillman 2006, Environ. Entomol. 35: 771 - 783). The number of N. viridula adults parasitized by Trichopoda pennipes (F.) was highly correlated with the number of stink bug adults in the sorghum trap crop, and percent parasitization of N. viridula adults by this parasitoid could reach up...
