Richard Hentschel, host of Green Side Up, talks with Russ Higgins, Agriculture Educator, about what insects are up to this time of year out there in the Farms of Northern Illinois. Russ discussed how deep the frost was and did it impact overwintering insects. In corn the concern will be the western corn rootworm beetle that overwinters as an egg and will survive quite well. Others will show up with winds during storms. Richard mentioned Japanese larvae that overwinter about 12 inches or so in the soil profile could be impacted by the cold soils and the Japanese Beetle larvae overwintering under the bark will not be impacted much at all.
