New Mating Disruption Treament to Be Used in Illinois

Chicago Press Release

New Pheromone Treatment Disrupting Gypsy Moth Mating to Begin in Northern Illinois

The Illinois Department of Agriculture is scheduled to start a new Gypsy Moth treatment program Thursday, June 25, in LaSalle and Ogle counties.

Applicators this year will use a new product called SPLAT.

SPLAT has the consistency of hand cream when applied and looks like candle wax after it dries. SPLAT is made from a mixture of water, wax and vegetable oils. It also contains preservatives and emulsifiers, which are the same ingredients used in skin care products.

“When the gypsy moth sex pheromone is added to SPLAT and the mixture is applied in the field, gypsy moth mating is disrupted and the pest population is reduced,” Warren Goetsch, bureau chief of Environmental Programs, said. “If most adult moths don’t mate, then fewer larvae will be present to cause damage to the leaves on trees.”

The Splat treatments are not harmful to humans. All ingredients are listed by the U.S. Environmental Protection Agency as being non-toxic. Spraying will begin in the areas listed below on Thursday June 25, but could be delayed in the event of poor weather conditions.
