SPRINGFIELD, Ill. The Illinois Department of Agriculture will hold four public information meetings to explain its plans this year to treat areas of northern Illinois for the destructive gypsy moth.

The meetings, which begin at 7 p.m., are scheduled March 16 in St. Charles, March 22 in Elgin, March 30 in Addison and April 6 in Oak Brook.

The first meeting will cover planned treatments not only in parts of St. Charles, but also in Batavia, Geneva, Valley View, Warrenville and Wayne. It will be held at the University of Illinois Cooperative Extension office, 535 S. Randall Rd.

The meeting March 22 will be held in the Heritage Ballroom at the Elgin Recreation Center, 100 Symphony Way, and explain plans to treat "spray blocks" in Bartlett, Elgin and Hoffman Estates. March 30, at Addison Village Hall, 131 W. Lake St. (just west of Lake and Addison), state agriculture officials will discuss treatment applications in Addison, Bensenville and Wood Dale.

The meetings will conclude April 6 with a presentation in Oak Brook Village Hall, 1200 Oak Brook Rd. (between York and Route 83). It will cover plans to treat Brookfield, Forest Park, Hinsdale, LaGrange Park, Lyons, North Riverside, Oak Brook, River Forest, Riverside, Westchester, Western Springs and Westmont.

The gypsy moth is a non-native pest that feasts on trees and shrubs. Large populations are capable of stripping plants bare, leaving them vulnerable to secondary insect and disease attacks.

Infested sites will be treated with applications of either BTK, a naturally-occurring bacteria used by gardeners as an environmentally-friendly alternative to chemical pesticides, or pheromone, a sexual attractant that confuses male gypsy moths and prevents them from breeding. The BTK will be applied by helicopter in late May to 3,933 acres. A fixed-wing airplane will apply the pheromone flakes to 22,500 acres in late June.

Maps of the treatment sites soon will be posted on the DuPage County Extension Service website at
