BMSB is the acronym for thebrown marmorated stink bug, a non-native species that's become a serious agricultural pest in the U.S.
Julianna Wilson is the tree and fruit IPM outreach specialist with Michigan State University.
Wilson says,
“It’s large. It’s shield-shaped, it’s brown, and it has this dark and light banding pattern along the margin of it’s abdomen.”
She says reports of the non-native pest skyrocketed from 6 to over 900 in Michigan after MSU put the word out on social media. Washtenaw County alone has nearly 40 cases so far.
