A Taxonomic Study of the Pupae of the Genus Dioryctria in the Southeastern United States (Lepidoptera: Phycitidae)1

Detailed descriptions, figures, and a key are given for the pupae of Dioryctria zimmermani (Grote), D. amatella (Hulst), D. disclusa Heinrich, D. clarioralis (Walker), D. pygmaeella Ragonot, and D. abietella (Denis and Schiffermuller). In comparing findings of the present species as the more northern insect, study with information in the literature, a difference was found in the number of setae present on pupae of so-called abietella of Florida and pupae of abietella ( abietivorella ) of northern United States and Canada. This apparently isolated population in the South possibly is not the same species as the more northern insect.
