Effect of Diflubenzuron on Plum Curculio Populations in Laboratory and Field Tests12

Abstract
In laboratory and field tests, egg hatch and larval development of Conotrachelus nenuphar (Herbst) were affected when adults were fed diflubenzuron (N-(4-chorophenyl) N′-(2,6-difluorobenzoyl) urea), but the effects were not long lasting. In laboratory tests with diflubenzuron, larvae held in treated soil had reduced pupation and eclosion at low dosages, but soil treatments in field environments were inconclusive.
