The brown marmorated stink bug, or simply the stink bug, is native to China, Japan, Korea and Taiwan. It was accidentally introduced into the United States, with the first specimen being collected in September 1998.
The brown marmorated stink bug is considered to be an agricultural pest, and by 2010-11 has become a season-long pest in U.S. orchards.
Most species of stink bugs are innocuous, only feeding on their host plants, and are seldom encountered by humans. Stink bugs feed on a variety of plants, including crop species. When stink bugs feed on tree fruits such as apples, it results in a characteristic distortion, referred to as “cat facing,” that renders the fruit unmarketable. Some species can cause damage in cotton and other crops.
Predatory stink bugs use their mouthparts to drain fluids from other pest insects. Some predatory stink bugs are important, beneficial insects in crops and gardens. They prevent caterpillars and other insect pests from destroying plants, trees, crops and gardens. Scientists are interested in using them as natural control agents of crop pests.
