Insect development is temperature dependent. We can use degree days to help predict insect emergence and activity. In warm years, insects emerge earlier, like we experienced last spring. Degree day accumulations are slightly behind the 11-year average. Home, Yard, and Garden readers can use the links below with the degree day accumulations above to determine what insect pests could be active in their area.
Degree day accumulations calculated using the Illinois IPM Degree-Day Calculator (a project by the University of Illinois Department of Crop Sciences and the Illinois Water Survey). (Kelly Estes)
