Practical, cost-effective, ecologically sound and readily adoptable integrated confinement and pasture fly management programs for dairy and beef cattle producers


2007 to 2012


Our studies are identifying practical, cost-effective and readily adoptable solutions that will aid dairy and beef cattle producers (both conventional and organic) in reducing the significant impact of confinement and pasture flies on their cattle.


The house fly and the stable fly are the predominant fly pests of confinement cattle, while the face fly and horn fly are the predominant fly pests of pastured cattle in the U.S. In recent years, the stable fly has emerged as a serious threat of pastured cattle as well. These flies, as well as horse flies, form a diverse pest complex that is extremely difficult to manage and that significantly affects confined and pastured dairy and beef cattle. The pending removal of many of the few remaining insecticides registered for fly control will create a crisis for the U.S. dairy and beef industry. It is crucial to have an effective, integrated approach to addressing this pest complex.


We continue to evaluate the release of different species of hymenopteran parasitoids for the control of house flies and stable flies in dairy calf coveralls. A new insecticide, Beauveria bassiana, was tested as a house fly bait in dairy barns. We are also evaluating new trapping technologies against stable and horse flies. We recently developed a targeted-application automatic sprayer for use against face and stable flies that utilizes a pyrethroid formulation. We are also investigating the use of NZI/Foil (insecticide-treated) fabric targets for the control of stable flies and face flies on pastured animals, along with conducting a survey of the dung beetle fauna (predators and competitors of horn flies and face flies) of dairy cattle pastures in New York.


We are working to evaluate, develop and identify effective methods for managing confinement and pasture flies. These studies will give dairy and beef cattle producers options to reduce flies' impact on their farms.
