Brown marmorated stink bugs are the latest in a long line of insect invaders which causes severe damage to agricultural crops.  They were first collected in Pennsylvania in the late 1990s, and since that time, have steadily continued westward across the United States.  This pest not only damages crops, but also likes to congregate in homes and other buildings as fall weather begins each year. Kelly Estes monitors and studies this and other insect pests for the Illinois Natural History Survey.  In this episode she discusses the biology of the brown marmorated stink bug, and its history and migration within the US.  She also discusses the risk it poses to Midwestern crops and the long-term outlook for its management.
