BROWN MARMORATED STINK BUG - Reproducing populations are now well-established in portions of southern Wisconsin. Soybeans, corn and other agronomic crops are at risk as this invasive pest becomes more widely distributed in the state. Feeding by BMSB on soybean pods and seeds results in 'stay green' symptoms, or soybeans that do not produce harvestable yields. Crop advisors and soybean growers should be alert for BMSB in 2017 and send any suspects to the UW Insect Diagnostic Lab for identification. Minnesota confirmed its first detection of BMSB in soybeans last August, in Dakota County bordering northwest Wisconsin.
