Insect development is temperature dependent. We can use degree days to help predict insect emergence and activity. 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).
