DODGEVILLE, Wis. -- Aerial spraying to control gypsy moth caterpillars is planned for 230 acres at Governor Dodge State Park this spring, including the Cox Hollow campground, the horse camp, Enee Point picnic area, and the Cox Hollow Lake beach and picnic areas.
Spraying will be done to reduce gypsy moth populations and prevent the moth's caterpillars from defoliating trees in the treatment area. The spraying will be coordinated through the Wisconsin Department of Natural Resources Gypsy Moth Suppression Program.
DNR staff will host an open house meeting to share information on the spray program. The open house will be held on January 31, in the Prairie Room at the DNR Dodgeville Service Center, 1500 N. Johns Street, Dodgeville, WI from 10-11 a.m. Questions can be directed to Kathy Gruentzel at 608-935-2315.
A small, low-flying airplane will apply Foray, an insecticide made from the naturally occurring bacteria Bacillus thuringiensis kurstaki also known as BtK, beginning early in the morning. Spraying will occur sometime between the middle of May and early June, depending on weather conditions and caterpillar development.
The gypsy moth is a serious forest and urban pest that was introduced into the United States from Europe in the 1860s. Gypsy moth caterpillars can kill oaks and many other tree species by eating all of their leaves during May and June. Caterpillars in high numbers can be a nuisance, ruining outdoor activities and increasing the chance of allergic reactions due to contact with the caterpillars.
