Emerging Pest of Dry Beans in Ontario
Native to North America, Western bean cutworm, Striacosta albicosta has been a long-time resident of the western Great Plains region until it began expanding its range eastward in 2000. First detected in Ontario in 2008, it has become established here and has become the primary pest of corn in Ontario. In 2014 , WBC damage was found in some dry bean fields in the Thamesville to Strathroy area. Since then, other dry bean growing areas of Ontario have found WBC damage, indicating that it becoming a new emerging pest for this crop.
