Clemson University officials are asking for the public’s help in tracking a new invasive insect that has begun appearing in South Carolina. Called the brown marmoset stinkbug, it can cause major infestations in houses, releasing a strong odor as it does so. It also threatens fruit trees, worrying many peach farmers in the state.
The stinkbug was first identified in Pennsylvania in 1998. It has spread through the Mid-Atlantic and South over the past ten years. Although it has some predators– such as snakes, lizards, and spiders– there are not enough to keep the population in check. Its primary predator in Asia is a species of parasitic wasp that does not exist in the United States.
The bug is mostly brown, but has a black and white checkerboard pattern around the edge of its body. Other than that border, it resembles the native brown stinkbug. However, there is one big difference: the Asian bugs gather in large groups, often causing an infestation.
“Basically, they like to hang out in large numbers together,” Sherry Aultman, the Cooperative Agricultural Pest Survey coordinator with Clemson’s plant industry department, said. “Part of the chemical smell they emit is actually signal saying ‘Hey, guys, come over here. I found something really good.’”
