“…The second treatment of pheromone to plots 2L1, 2L2, and 2L3 in 1990 was applied on July 16. All pheromone treatments were made using specialized equipment (Schwalbe et al, 1983) attached to a Cessna 206 aircraft and calibrated to deliver 75 g active ingredient (a.i.) in 405 g flakes per hectare per application.…”

“…Studies on the use of the sex attractant pheromone, (Z)-7,8-epoxy-2-methyloctadecane or disparlure (Bierl et al, 1970), for disruption of mating in lowdensity populations have been carried out for the past 15-20 years (Cameron, 1981). Tests of aerially applied, controlled-release formulations of dispaflure conducted in the late 1970s (Webb et al, 1981) showed that gypsy moth mating was reduced by approximately 70-85 % or more depending upon the population density and the applied dose (Schwalbe et al, 1979(Schwalbe et al, , 1983. Dose-response studies (Webb et al, 1988) showed that the degree of mating disruption increased as the amounts of dispaflure in plastic laminate flakes was increased from 7.5 to 75 g/ha in aerially treated plots.…”

This four-year study demonstrated that low-density populations of the gypsy moth,Lymantria dispar (L.), were effectively suppressed by annual aerial application of 75 g of racemic disparlure per hectare formulated in plastic laminate flakes. These tests also showed that, when plots were treated with 150 g of pheromone per hectare in 1990 only and left untreated for the following three years, populations continued to be suppressed in 1991-1993 as compared with the controls. Although none of the plots were treated in 1994, population assessment continued and showed that the gypsy moth population density remained low in the plots that had been treated annually for the preceding four years. The laminate flakes released an average of 0.48 g disparlure per day per hectare from each of the two applications in 1990, and 0.72 g per day per hectare from the single application in each of the following three years (1991-1993). Only 27-40% of the applied pheromone dose was emitted during male moth flight.

“…Mating disruption works best at low population densities (Schwalbe et al 1983, Webb et al 1990). It is not suitable for suppression of outbreak populations, but can be used to eradicate small isolated colonies with low population density.…”
