Brown Marmorated Stink Bug (Halyomorpha halys)
Posted on: September 23, 2020 by Nic Usabel
The Brown Marmorated Stink Bug (BMSB) is an invasive insect pest from eastern Asia. Its first North America detection was in Pennsylvania in 1996. BMSB adults were first discovered in Canyon County in May 2012 and in Ada County in October 2014. This year a location with traps adjacent to orchards in Canyon and Payette counties participating in the SCRI nationwide survey has collected five (5) BMSB in two subsequent weeks.
If you believe you have found BMSB in Idaho take a specimen to your local Extension office or contact the Idaho State Department of Agriculture’s Pest Survey Program at (208) 332-8627.
BMSB has a shield-shaped body with mottled brownish-grey coloration. The adults are just over ½ inch long, and their antennae are marked with distinctive white bands. The insect’s underside is white with gray or black markings, and its legs are brown with faint white banding. Unlike most native stink bugs, BMSB has smooth “shoulders”. BMSBs have distinctive black and white “skirting” around their abdomens that protrudes from under the wings. See image.
BMSB has a broad host range that includes fruit, vegetable, ornamental, and field crop plants. The insect has a mouthpart for piercing and sucking plant sap and prefers fruits and seeds pods (reproductive structures). In Utah, the catalpa tree has shown the greatest numbers during detection and assessment of invasion risk.
