End Date: Jan 31, 2015
Methodologies to achieve the objectives: 1) Examine the morphology and structure of sensory organs of stable fly adults and larvae. 2) Electrophysiological techniques will be used to identify attractant constituents associated with host animals (breath and skin emissions, etc.) and oviposition substrates (livestock animal manures and decomposing organic matter such as silage, rotting hay, and grass/alfalfa clippings) 3) Identify and evaluate novel repellents on stable fly populations. 4) Use visual and landscape features to develop a spatiotemporal model of stable fly dispersion that will describe and predict habitat use and suitability for larvae and adults. 5) Develop formulations of identified attractants and repellants for field application. 6) Reduce stable fly populations in confined and pastured cattle with Push-Pull strategy. 7) Take a holistic approach to reduce the development of immature stable flies by examining the biological, chemical, and physical characteristics of larval developmental sites and develop tools to modify these sites to render them unsuitable for stable fly development. Though this research will be directed at a better understanding of the stable fly habitat, other filth flies developing in similar habitats will be examined. 8) The limits of chemical and physical properties on survival of both stable flies and house flies will be studied in the laboratory. 9) Patterns of stable fly and house fly larval dispersal in relation to physical and chemical factors will be studied in the laboratory. 9) Mark release recapture studies will be performed in the field to study stable fly larval dispersal. 10) Antibiotics and food preservatives will be tested in the in the laboratory and then the field to determine their effect on stable fly survival. 11) Self marking technique will be usedat stable fly larval development sites to study the dispersal distances from these sites.
