Compatibility of coprophagous scarabs and fimicolous staphylinids as biological control agents of the horn fly, Haematobia irritans (L.) (Diptera: Muscidae)
Environmental Entomology 12 (1), 124-183
Abstract: Low numbers of the introduced scarab Onthophagus gazella (F.) and a native scarab Onthophagus oklahomensis Brown did not enhance predation by the horn fly egg predator Philonthus flavolimbatus Ericson in laboratory tests. In both laboratory and field tests, high numbers of O. gazella and native scarabs caused significant reductions in staphylinid reproduction. The results of this study indicate that dung-burying scarabs may not be compatible with other biological control agents of the horn fly.
