Brown marmorated stink bug update

Hannah Fraser, Entomology Horticulture Program Lead, OMAFRA

An adult brown marmorated stink bug (BMSB) was caught in a trap at another one of our survey sites in Niagara, near Niagara-on-the-Lake. The presence of adults in traps indicates growers / consultants need to be on the look-out for this pest in their crops. It is very easy to miss BMSB when it is at low levels. This pest is highly mobile, and the adults can move in from adjacent areas at any point in the growing season. See the OMAFRA website for management recommendations. It is likely this will be revised as we learn more about the biology of BMSB in Ontario.

Brown marmorated stink bugs have been confirmed as established (breeding populations) in Hamilton, London, Newboro, St. Catharines, and Windsor, ON. In addition, we have captured adult BMSB in pheromone traps set up on commercial farms near Beamsville, Cedar Springs (2013), Essex, Niagara-on-the-Lake, St. David’s, and Waterdown. There have been homeowner finds (indoors) in the Golden Horseshoe and GTA (Hamilton, Burlington, Milton, Toronto, Vaughan, Niagara-on-the-Lake, St. Catharines, Niagara Falls, Fort Erie, Stoney Creek), Western Ontario (Cedar Springs, Essex, Windsor, Kincardine, London, Paris, Tecumseh, Maidstone), and Eastern Ontario (Newboro, Ottawa)
