BIOLOGICAL CONTROL Hymenopteran Pupal Parasitoids Recovered from House Fly and Stable Fly (Diptera: Muscidae) Pupae Collected on Livestock Facilities in Southern and Eastern Hungary

This Þeld survey, the second noting the occurrence and diversity of Þlth ßy pupal parasitoid fauna in Hungary, was performed on beef and dairy feedlots and swine facilities in the southern and eastern parts of the country. The Þlth ßies Musca domestica L. and Stomoxys calcitrans (L.) were the two most commonly parasitized hosts. The three species of Spalangia recovered, in decreasing order of abundance, were S. cameroni Perkins, S. nigroaenea Curtis, and S. endius Walker. Pachycrepoideus vindemiae Rondani, Trichomalopsis sp., two apparently undetermined Diapriidae spp. and one apparently undetermined Brachycera sp. are believed to be new country records.
