Abstract
The role of natural enemies in the control of the pear psylla, Psylla pyricola Foerst., has been of minor importance in the published history of this pest in North America. Jensen (1957) listed six species of parasites that attack the pear psylla nymph, but only one, Psylledontus insidiosus Cwfd. (Hymenoptera: Encyrtidae), is recorded from North America. Slingerland (1896) stated that the predators Chrysopa oculata Say (Neuroptera: Chrysopidae) and Adalia bipunctata (L.) (Coleoptera: Coccinellidae) were observed in the field feeding on psyllid eggs, nymphs and adults. Georgalla (1957) reported that Anthocoris nemorum L. (Hemiptera: Anthocoridae) fed upon pear psylla eggs and nymphs, but made no reference to effect upon psyllid populations.Keywords
