The effects of weekly manure removal, monthly removal, and no removal on populations of fly larvae and selected predators (Acarina: Macrocheles muscaedomesticae Scopoli, Fuscuropoda sp. (undescribed), Parasitidae; Coleoptera: Staphylinidae, Histeridae, Hydrophilidae; Diptera: Ophyra leucostoma (Wiedemann)) were studied for a full fly season at each of 2 northern California ranches. Third-instar larvae of the house fly, Musca domestica L., the false stable fly, Muscina stabulans (Fallen), and Calliphoridae were most abundant in 1-week-old manure; those of the little house fly, Fannia canicularis (L.), the coastal fly, Fannia femoralis Stein, and the black garbage fly, O. leucosloma, reached greatest numbers in 2- to 3-week-old manure. Unremoved manure had the least numbers of dipterous larvae, with the exception of the stable fly, Stomoxys calcitrans (L.). All predators studied were most abundant in unremoved manure. Abstention from manure removal favored the predators; monthly or bi-weekly removal favored the dipterous larvae.
