Gypsy moth treatments for May completed

Next treatments in mid-June for eight counties

Gypsy moth aerial treatments were completed in portions of Allen and Lake counties this morning, finishing aerial treatments for these counties for this year.

In mid-June, portions of Adams, Grant, LaPorte, Marshall, Miami, Porter, Starke and Wabash counties will receive mating disruption aerial treatments using Disrupt II. The Allen and Lake county treatments this morning were of a different variety. They used Btk (Bacillus thuringiensis var. kurstaki) Foray 76B, a bacterium commonly found in the soil and frequently used in organic farming.
Maps for the June treatment sites and further information about gypsy moths may be found at A news release will announce the treatment date, which likely will be during the week of June 20.  Treatment updates also will be posted on Twitter at!/INdnrinvasive.

The selected June sites in each county will receive one application of Disrupt II. This treatment, which will start in early morning under favorable conditions, is usually completed in the afternoon.  If rain or high wind prevents completion of a treatment, it will be completed on the next suitable day.

The spread of gypsy moths has been controlled successfully for more than 25 years in Indiana, where it has been confined to small, isolated infestations, primarily in the northern Indiana. The Slow the Spread Program for gypsy moths is a collaborative effort between DNR Entomology & Plant Pathology and DNR Forestry, with most of the funding provided by the U.S. Forest Service.
