High populations of pest flies on swine facilities can be detrimental to the animals and producers. The purpose of this study was to identify the distribution pattern and the influence of habitats on distribution of adult biting flies surrounding commercial swine production barns in North Carolina. In this study, fly surveillance was conducted on four swine facilities in Bladen County, North Carolina, U.S.A., from January to October 2019. Biting flies typically associated with livestock were passively collected weekly on sticky traps, which were placed in three concentric circles surrounding swine barns, and then counted and identified. Stable flies [Stomoxys calcitrans (L.); Diptera: Muscidae] were most abundant on swine facilities that were mixed-use with pastured beef cattle. However, swine producers with no pastured cattle should be aware of the potential for stable flies to disperse from off-property larval development sites. Therefore, adult fly management may be necessary if populations reach nuisance levels. Horse and deer fly (Diptera: Tabanidae) captures were not related to trap proximity to water. Differences in horse and deer fly trap captures was likely less of a reflection of differences in potential fly development habitat quality (e.g., water) and more related to adult fly habitat selection.
