Growing populations of brown marmorated stink bug could harm late-season crops

Oregon State University researchers warn of an increased risk of damage to late-ripening crops this year after discovering record levels of the brown marmorated stink bug, a newly established invasive pest in Oregon.

The alert comes at a critical time with harvest looming for many crops, including blueberries, raspberries, apples, pears, hazelnuts, grapes, sweet corn, peppers, and edible beans. The pest has shown an appetite for more than 100 different crops.

Late-season feeding and contamination by adult stink bugs and nymphs can result in discoloration of fruit, vegetables and nuts – ultimately sullying the crops' value at the marketplace. While no economic damage from the pest has been documented thus far in Oregon, OSU researchers worry that could change after this summer.
