Abstract
The plum curculio, Conotrachelus nenuphar Herbst (Coleoptera: Curculionidae), is a key pest of apple orchards of North America. In absence of chemical treatments, up to 85% damage is caused to the fruit at harvest. In spite of its importance, plum curculio is one of the least known pest of apple orchards. This paper reviews research advances that were made since 1992 to implement sound IPM programmes against this pest. These advances include behavioral studies, trapping methods, attractants, entomogenous nematodes and treatments of peripheral zones, with special reference to apple orchards. Plum curculio management achieved through peripheral-zone treatments have been successful in commercial situations.
