Hymenopterous parasites of the hemlock sawfly, <i>Neodiprion tsugae</i> Middleton, in southeast Alaska, with a key to larval remains
Keywords:
parasites, hemlock sawfly, <i>Neodiprion tsugae</i>Abstract
A key is supplied to identify parasitic Hymenoptera reared from hemlock sawfly cocoons in southeast Alaska. The key is based on the size of the exit hole in the host cocoon, and characters visible on the final-instal' larval skin. Brief biologIcal and descriptive notes are given for each species appearing in the key.References
