Abstract

A radiographic technique has been developed for observing and quantifying development and mortality of Blepharipa scutellata ( Robineau-Desvoidy), Parasetigena agilis (Robineau-Desvoidy), and Compsilura concinnata (Meigen), tachinid parasites of the gypsy moth, Porthetria dispar (L.). Puparia can be examined and sorted immediately after collection and decisions on further collecting and release can be made in the fall. Healthy tachinid pupae can be placed directly in a release area eliminating the handling of adults the following spring.
