Abstract
The gypsy moth, Porthetria dispar (L.), mating disruption capabilities of a microencapsulated formulation of 2-mcthyl- cis -7-octadecene, the olefin precursor of disparlure, were evaluated in field tests on Cape Cod, Mass., and in central Pennsylvania. Neither preseason nor inseason applications of up to 61.75 g/ha of the olefin disrupted mate-finding or reduced trap catches to levels theorized to be necessary for population control. Disparlure applied at 15 g/ha significantly reduced fertilization of females in test plots; olefin applications at the same rate did not.Keywords
