ABSTRACT
This chapter reviews the guild of beetle and mite predators in poultry manure and to identify areas where additional information is needed to support filth fly IPM programs. P. monospinosus is a species that recently has been described from specimens collected from caged layer houses in North Carolina, where it is often present in high numbers in the first few weeks of manure accumulation. Adults and deutonymphs feed on house fly eggs and first instars. Female mites prefer first instars over fly eggs, and can destroy twenty-four fly immatures per day. Fuscuropoda vegetans occupies a niche that distinguishes it from other mites in the poultry manure ecosystem. Carcinops pumilio is the most common histerid found in poultry manure throughout much of the world. Adult beetles and both larval instars are predaceous. In poultry houses, adults feed preferentially on house fly and other large muscoid fly eggs and newly hatched larvae.
