The brown marmorated stink bug (BMSB) was recently detected for the first time in Minnesota soybean. A single adult specimen was collected in sweep net samples from a soybean field in Dakota County on August 17, 2016. Follow-up sampling of that same field performed on August 25, 2016 did not detect any additional BMSB. This invasive pest of Asian origin uses piercing-sucking mouth parts to feed on developing soybean pods and seeds. In more easterly states, this insect has caused significant yield losses to soybean and other crops. In Minnesota, we are unaware of any fields with densities of stink bugs near treatable levels; therefore, we do not envision any insecticide treatments being needed for this pest at this time. The intent of this article is to alert you to the presence of this new invader, which could become a threat to Minnesota crops in the near future. Further information on BMSB and other sti…
