The Cleptoparasitic Habits and the Immature Stages of Eurytoma pini Bugbee (Hymenoptera: Chalcidae), a Parasite of the European Pine Shoot Moth, Rhyacionia buoliana (Schiff.) (Lepidoptera: Olethreutidae)

Abstract

Eurytoma pini Bugbee (Bugbee, 1958), a common parasite of the European pine shoot moth, Rhyacionia buoliana (Schiff.), in Ontario, was previously recorded from this host as E. appendigaster (Swed.) (Coppel and Arthur, 1953) and as E. thylodermatis Ashm. (Miller, 1953). Bugbee (1958) recorded it from various lepidopterous hosts that mine in plant tissues. These include: the Nantucket pine tip moth, Rhyacionia frustrana (Comst.); the bagworm, Thyridopteryx ephemeraefomis (Haw.); the ragweed borer, Epiblema strenuana (Walkr.); the lima bean borer, Etiella sp.; the pink bollworm, Pectinophora gossypiella (Saund.); Acrobasis rubrifasciella Packard; and Eucosma scudderiana (Clemens). Bugbee stated that the range of E. pini probably includes all of the pine growing regions of North America.
