Stink bugs are fierce prehistoric looking bugs. Some are indeed quite fierce and others stink more than they bite! In many parts of the world including their native range of China, Japan, Korea and Taiwan the brown marmorated stink bug (Halyomorpha halys) is considered an agricultural pest. Yet other genera of stink bugs, specifically the Podisus nigrispinus (Dallas), are considered an important biological control agent for other insect pests in the cotton, soybean, tomato, corn, and kale fields.
