8 August 2019. Pheromone trap catches confirm WBC presence in nearly regions of New York State. NEWA WBC modeling indicates the threshold of 25% flight completion for egg mass scouting has been exceeded in all areas of the state. All areas but the eastern Lake Ontario shoreline and the St. Lawrence Seaway are at 50% to 100% flight completion.
An important reminder that WBC estimated flight emergence is only applicable when presence has been confirmed. Visit the NYSIPM Sweet Corn Pheromone Trap Report blog, updated weekly, to find detailed WBC trap catch information for your area, along with European corn borer, corn earworm, and fall armyworm.
