In the study of arthropods in poultry manure, the key predator of house fly larvae encountered was the beetle Carcinops pumilio Erichson (Coleoptera: Histeridae) (Achiano and Giliomee, 2003, 2005a, b, 2006a, b).

This trend was stronger at the ends of the houses where airflow is faster than in the relatively still-air center of t...

Poultry manure supports the development of several serious fly pests (Axtell and Arends 1990). Fresh manure is rich in nutrients and is produced at the rate of one-quarter pound per hen per day, providing an ideal habitat for fly larvae to live and feed. The problem has become more acute in modern high-density poultry housing where manure often is concentrated in piles below the birds. The hous...
