Blackberry and Raspberry-Brown marmorated stink bug

Halyomorpha halys

This pest is not currently of commercial concern as SWD management programs tend to keep brown marmorated stink bug (BMSB) populations in check. BMSB secrete a defensive chemical that can be absorbed by the fruit, resulting in unpleasant flavor. Raspberries are most easily contaminated with the defensive compound, and late-fruiting caneberries are most susceptible to damage. It is present in the Pacific Northwest but has not caused significant damage to berry crops. It may pose a significant risk to fruit if populations increase.
