The first western bean cutworm (WBC) moth was caught in Ontario this week, a month later than usually expected, according to Tracey Baute, field crop entomologist with Ontario’s Ministry of Agriculture, Food and Rural Affairs (OMAFRA).

Baute writes how peak flight for WBC usually occurs during mid-July, but the delay in growing degree days this year has also pushed the development of WBC.
