Adults tend to aggregate into groups when arriving at overwinter sites, creating nuisance problems for homeowners, says Kevin Rice, the director of the Alson H. Smith Jr. Agricultural Research and Extension Center at Virginia Tech.
In the spring and summer, these insects feed on a wide variety of fruit and vegetable crops.
“I have focused on novel trap design for monitoring brown marmorated stink bugs and quantifying their movement patterns among landscapes,” Rice said. “I’m currently collaborating with a team of engineers and entomologists to use UV lasers and UAV to track brown marmorated stink bug movement among different landscapes.”
Rice said there is also hope that biological control agents may help control the bugs. In 2014, a small parasitoid named the Samurai wasp was discovered attacking brown marmorated stink bug eggs. This wasp was not introduced to the United States by scientists, but rather made the voyage on its own from Asia.
There, samurai wasps kill up to 70 percent of brown marmorated stink bug eggs.
Since their unexpected arrival in the U.S., the samurai wasp has spread across the Mid-Atlantic and might be responsible for reduced brown marmorated stink bug populations.
For homeowners, other Virginia Tech researchers found a simple way to trap them using an aluminum pan, light, and dish soap, shown in the video below.
