Contributions of the American Entomological Institute. Volume 19, Part 7. The Ichneumonid Parasites Associated with the Gypsy Moth (Lymantria despar)

摘要

The purpose of the present study was to establish the identities of the various ichneumonid species that have been reported as parasites of the gypsy moth. Over a hundred species of the Ichneumonidae have been recorded as primary parasites and nearly 25 as secondary parasites. On the basis of these studies, 24 species of Ichneumonidae are confirmed as parasites of the gypsy moth in the world, 31 species are shown definitely not to be associated with the gypsy moth, and 38 species are listed as unconfirmed records from the gypsy moth. Some of these may be occasional parasites, while some others appear to be misdeterminations. The report describes the identity of the species.
