Filth Fly Impacts to Animal Production in the United States and Associated Research and Extension Needs.

Many flies are considered serious pests of livestock, poultry, and equids. These pests can negatively impact animal welfare and contribute to considerable production losses. Management of filth fly pests in particular, including the house fly (Musca domestica L.), stable fly (Stomoxys calcitrans (L.)), horn fly (Haematobia irritans (L.)), face fly (Musca autumnalis De Geer) (Diptera: Muscidae), and little or lesser house fly (Fannia canicularis (L.) (Diptera: Fanniidae)), has been a research and Extension priority of veterinary entomologists for many decades. However, ongoing changes to animal husbandry and production practices, coupled with an increasing development of behavioral and physiological resistance to insecticides require renewed focus on new and more effective management strategies. This article is the first in a series of updates to these historical reports and the purpose is to serve as a resource for veterinary practitioners, consultants, funding agencies, veterinary entomologists, industry, commodity groups, and the scientific community working towards control of these pests. Companion articles will review individual filth fly species of importance to animal agriculture in the United States [ABSTRACT FROM AUTHOR]
