Abstract
The thickness of the wall of the puparium of the apple maggot, Rhagole tis pomonella (Walsh), increased as the puparium aged. The force requi red to pierce the wall of the puparium also increased with age, and th is relationship was best described by a cubic polynomial. Increasing t hickness and hardness of the wall of the puparium will likely influenc e the efficacy of the parasite Phygadeuon wiesmanni Sachtl.
