Developmental sites of immature stages of the stable fly and house fly (Diptera: Muscidae) found outside of cattle feedlot pens and the overwintering of the stable fly
Abstract
The immature stages of the stable fly, Stomoxys calcitrans (L.) and house fly, Musca domestica L., were monitored in ten potential breeding materials found outside cattle feedlot pens. Samples were taken over a three year period. Samples were also taken from piles of grass clippings in urban suburban areas over a two year period. Samples taken along the back fence and along the perimeter of sewage lagoons produced few immature stages of the house fly or stable fly. Very few stable fly larvae were collected from the silage in bunker silos or haylage. The stable flies were most consistently produced in samples from the runoff ditch. Largest numbers of stable flies were collected in samples from grass clippings, spilled silage, silage at the base of the bunker silo and spilled silage. The immature stages of the house fly were rarely collected from piled manure and grass. Spilled grain, haylage, and spilled grain produced large numbers of house fly immatures. Although these two species develop in similar habitats, they were collected together in only 3% of the samples collected. Differences in the physical parameters of the materials and a seasonal separation of the two species may be an explanation. Adult stable flies were monitored during three winters at two, four, and 13 locations with Alsynite fiberglass traps and by examination of the interiors of buildings. No stable flies were found inside buildings during the winter. Adult stable flies were consistently caught on Alsynite traps at one location during two winters and at two other locations during one winter. Distribution and physiological age of these flies indicate that they emerged from pupae that had developed at or near the location where they were captured. Potential breeding sites were examined. A few third instars were found in silage in midwinter, but silage should nor be considered a major source for overwintering stable flies.
