Using Frozen Host Pupae to Increase the Efficiency of a Parasite-Release Program
Abstract
Continued, periodic additions of frozen house fly pupae, Musca domestica L., were used to augment an adult-release program of the wasp Pachycrepoideus vindemiae (Rondani) in chicken houses in Maryland. A one-month long wasp release program, which was supplemented and followed by deposits of frozen fly pupae, was equally or more effective in killing house fly pupae than a program of continued releases of adult wasps. Both programs resulted in an increased house fly pupal mortality of 22-44% compared to that in an untreated check house.Downloads
