Second treatments are set for Tuesday May 24
The first of two rounds of gypsy moth aerial treatments in selected portions of Allen, Lake and Porter counties were completed late Friday afternoon after morning fog delayed the start of treatments.
Follow-up treatments for Allen and Lake counties are planned to begin tomorrow, Tuesday May 24. If the weather conditions change, treatments will be delayed until the next suitable day. Affected areas include: Allen County (Bremer Road 11; Hadley Road 11; Kroemer Road 11) and Lake County (Highland and Springrose Heath).
The follow-up treatment for the Porter County site 350 East will occur in mid- to late June using mating disruption. News releases and updates on the gypsymoth.IN.gov website will notify the public of the treatment time in June.
Maps of the treatment sites and further information about the gypsy moth also may be found at gypsymoth.IN.gov. Treatment updates will be posted on the Indiana gypsy moth Twitter site at http://twitter.com/#!/INdnrinvasive.
People in and near treatment areas might notice a yellow crop duster airplane flying 50-125 feet above treetops as it performs the treatments by releasing Btk (Bacillus thuringiensis var. kurstaki) Foray 76B, a bacterium commonly found in the soil and frequently used in organic farming.
When a gypsy moth caterpillar consumes a leaf with Btk on it, its digestive system is disrupted; it stops feeding and succumbs. Although Btk affects only feeding caterpillars, people who live or work near the treatment areas may choose to remain indoors during the treatment, and for about 30 minutes after the treatment is completed, which allows time for the Btk product to adhere to leaves. They also may choose to bring outdoor pet food and water dishes inside.
Aerial applications typically begin between 5:30 and 6 a.m. (Eastern) and continue through the day as weather and flight schedules permit. With favorable conditions, the treatments are usually completed by early 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.
