Brown marmorated stink bug (BMSB; Halyomorpha halys Stål) is an invasive insect that first invaded Utah in 2012. It has since caused urban nuisance problems for northern Utah residents and poses a serious threat to various commercial fruit and vegetable crops. In June 2019, the samurai wasp (Trissolcus japonicus (Ashmead)) was discovered in Salt Lake City. This exotic parasitoid wasp is the most promising agent for biological control of BMSB and is uniquely evolved to lay its eggs inside of BMSB eggs. Help us protect parasitized egg masses in the wild by becoming familiar with the photos below.
