To Be Ser ve tter GroweOur rs Be on the LOOKOUT An identification card has been issued to help people distinguish a brown marmorated stinkbug from other species. by Geraldine Warner G rowers in Washington State are urged to be on the lookout for the brown marmorated stinkbug. The bug recently became established in Clark and Skamania counties in southwest Washington and has also been detected in Yakima and Thurston counties. Washington State University and the state Department of Agriculture have issued an identification card to help growers distinguish this new pest from native stinkbugs they might encounter. The brown marmorated stinkbug lays eggs in clusters of 28 on the undersides of leaves. Nymphs that hatch from the eggs develop through five instars. Adults can be recognized by their fully developed wings. Growers will need to look closely to tell the differences from other stinkbugs. The brown marmorated stink bug (Halyomorpha halys) has white bands on its antennae whereas Euchistus, Holcostethus, and Brochymena species do not. The brown marmorated stinkbug and Holcostethus have smooth shoulders, but the others have toothed shoulders. Growers who think they might have found the bug are encouraged to take a sample to their local extension office ( or contact tmurray@, (509) 427-3931) or, (360) 902-2063.
