Abstract:

Duplicate experiments were conducted in Massachusetts and Maryland to evaluate 7 aerially applied controlled-release formulations of disparlure for gypsy moth mating disruption. The incidence of mating of female moths was significantly less in treated plots than in untreated plots. Depending upon the formulation sprayed, mating in treated plots over the season was reduced 83 to 21% from that in control plots in Massachusetts; the mating reduction in Maryland treatment plots varied from 97 to 19%. Several formulations reduced mating throughout the entire flight season. In plots treated with the most effective formulation (1976 2% NCR microcapsules), the mating reduction dropped to 73% in Massachusetts during peak flight, when most male moths were present. With this same formulation, the mating reduction in Maryland, where more sparse populations existed, was at least 88% throughout the test.
