Cold winter temperatures this past winter have caused a lot of people to reflect on that age-old question, "What effect is all this cold weather going to have on the bugs?" A corn rootworm survival study was conducted by Mike Gray and Jon Tollefson at Iowa State University during the winters of 1983-1985 may help to answer part of this question. The study examined the influence of different tillage methods and winter weather on rootworm egg survival.
