Therefore, studies were conducted to evaluate different control options for P. guildinii. Among the studies conducted was the current status of egg parasitoids of stink bugs in Louisiana. Telenomus podisi Ashmead (Hymenoptera: Platygastridae) was the predominant egg parasitoid of stink bugs. Field studies were also conducted to determine the combined effects of host plant resistance and insecticide application, on the abundance of stink bugs and their natural enemies. The soybean cultivar Pioneer 95Y20 had the least pest pressure, seed damage, and yields were higher from these plants. Insecticide application of thiamethoxam provided some control of stink bugs, although it did not impact yield. The combination of cultivar and insecticide application did not have a significant effect on natural enemies of stink bugs.
