title: Failure of Hydrotaea aenescens, a larval predator of the housefly, Musca domestica, to establish in wet poultry manure on a commercial farm in Florida, USA.
abstract: Hydrotaea aenescens (Weidemann) (Diptera: Muscidae) larvae and pupae were released in high-rise pullet houses in Pascoe County, Florida, U.S.A., for biological control of houseflies, Musca domestica L. (Diptera: Muscidae), in three separate tests during a 14-month period (April 1994-May 1995) and did not become established. However, H. aenescens believed to be from our releases did become established at a caged-layer farm 0.3 km from the release farm. Moisture in pullet house manure generally exceeded 80%, which is above the level at which H. aenescens is reared in colony. Caged-layer manure was also very wet, but crusted areas provided sites for H. aenescens larval development. Results demonstrate that H. aenescens adults will disperse from release sites and populate preferred sites without becoming a nuisance.
