The brown marmorated stink bug (BMSB)

Damage can be substantial when BMSB populations are not identified early and managed appropriately. Apple growers in the Mid-Atlantic States have reported losses of $37 million representing 18% of their fresh apple market.  Growers and wineries are also concerned that the “stink” from any bugs accidentally crushed in wine or juice grapes could taint the product with off flavors. This insect should concern homeowners as well, since people in the Mid-Atlantic States have reported large populations of BMBS overwintering in their homes and becoming a nuisance. 

BMSBs resemble some other California stinkbugs such as the rough stink bug, a beneficial predator of other insects.  If you think you’ve found a BMSB, or any other odd or unique looking insect pest, you should collect it and bring it to your local university advisor, ag commissioner or state ag department entomologist for proper identification.  Early identification of invasive pests is critical for protecting California’s billion dollar agricultural industries.
