Abstract

A few areas of Iowa are approaching 50 percent corn rootworm egg hatch now (Figure 1), including the Muscatine area. Many other regions will be reaching 700 degree days within 7-14 days, depending on future temperatures. Cooler spring temperatures in 2013 have slowed down development, especially compared torootworm hatch last year.
