Tracking Pests with Growing Degree Days

Posted on May 3, 2012 at 4:11pm 0 Comments

Insects rely on warm temperatures to grow, and thus their emergence and life cycle progression can be tracked by tracking the "heating units" that accumulate each day. This is referred to as growing degree days.

During the "How Pests Pester your Trees" webinar today, I was asked what references I use. I use a lot. Here is a short list. Some of these are for keying out, some would be used for verification of ID. Most of these do not include management recommendations; that's a different list!
