Abstract: Gypsy moth insecticides have evolved from broad spectrum, persistent, environmentally hazardous compounds to highly specific and relatively environmentally benign products. Chief among these new tools is the use of Disparlure, the synthetic gypsy moth mating attractant. This compound is applied aerially and serves as a mating disruptant with profound positive effects in halting gypsy moth mating and subsequent population growth. Our work in the STS Project with fine tuning both the concentration and application of Disparlure has led to an overwhelming increase in the use of this product within the STS Project area. Since 1995, when mating disruption was first used in STS, it has grown from 7% of the 35,238 treated acres to 81% of the over 441,000 acres treated in 2007. We are now able to apply rates of 6gm/acre as opposed to earlier concentrations of 32gm/acre. Disparlure now is approximately 1/3 the cost per acre as Btk and has fewer environmental effects. This is especially valuable in areas with threatened and endangered lepidopteran species.
