Research Project: HIGHER DIPTERA PESTS OF LIVESTOCK, POULTRY, AND HUMAN HEALTH: INTEGRATED PEST MANAGEMENT AND ADULT BIOLOGY

Location: Mosquito and Fly Research Unit

Project Number: 6036-32000-047-00
Project Type: Appropriated

Start Date: Nov 20, 2009
End Date: Oct 26, 2014

Objective:
1. Provide better tools for surveillance and risk assessment by: studying house fly feeding behavior, resource location, and nutrition under field conditions; developing more efficient stable fly attractants; studying specific behaviors of adults; and determining the risk of introduction of Stomoxys species other than calcitrans and prioritize the risk of other potentially invasive fly species, including traps that sample across the entire population of adults and produce results with quantifiable error terms. 2. Develop more efficient integrated pest management by determining weaknesses within fly life cycles and matching these weaknesses to appropriate chemical control methods; and by developing biologically-based and bio-rational control methods. 3. Conceive and test applications of behavior-altering methods (e.g., behavior altering devices, attractants, repellents) for practical use, including repellents for livestock. 4. Determine the role of flies in dissemination of priority food safety pathogens including the role of some of the less-studied species of flies.

Approach:
Nutritional attractants of house flies will be identified and new chemical lures for stable fly traps will be developed. Trapping data will be used to determine the risk of introduction of exotic Stomoxys spp. at ports in the southeastern U.S. Virus-based baits from candidate strains will be developed to control house flies. Systems for production of Diapriid parasitoids will be ready for transfer to commercial insectaries. These parasitoids can be effective for management of immature stable flies and house flies. New stable fly repellents for use on livestock will be evaluated in laboratory and field trials. Behavior-altering chemicals/surface combinations to repel and/or kill house flies will be evaluated in the laboratory with the aid of video monitoring and evaluation systems. An insecticide-based perimeter treatment method to provide protection against dispersing flies will be subjected to final field evaluations. The role of house fly in transmission of Salmonella enteriditis via contaminated poultry feed will be determined by exposing flies to contaminated feed and measuring their ability to transfer the pathogen to clean substrates.
