|Abstract:||PURPOSE: This technical note examines and quantifies the effect of parasitism by Trichopria columbiana Ashmead (Hymenoptera: Diapriidae) on Hydrellia spp. emergence and also considers the influence and subsequent impact of these actions on population size in ponds at the Lewisville Aquatic Ecosystem Research Facility (LAERF), Lewisville, Texas. Field parasitism rates by T. columbiana were quantified and host selection behavior recorded. Host selection was examined by providing access to various immature life stages of Hydrellia pakistanae Deonier and quantifying oviposition behavior and wasp emergence.|
