Research Project: Management of Filth Flies

Location: Mosquito and Fly Research

Project Number: 6036-32000-049-00-D
Project Type: In-House Appropriated

Start Date: Oct 27, 2014
End Date: Oct 26, 2019

Objective:
1. Evaluate the effects of climate change on filth fly populations and their natural enemies. 1A. House fly management under high temperature conditions. 1B. Verify seasonality, resource preference and range of Stomoxys niger in East Africa. 2. Increase the efficiency of integrated pest management programs by the development and improvement of traps and behavior-altering surfaces and chemicals. 2A. Identify and develop stable fly optical or chemical attractants which will improve trap efficacy. 2B. Conceive of or develop applications for behavior-altering devices, surfaces and chemicals (e.g., attractants, repellents, and pesticides) for practical use on and around livestock and poultry. 3. Develop management techniques for fly larvae. 3A. Development of more effective larval detection and control techniques for filth flies. 3B. Autodissemination of Insect Growth Regulators (IGR’s) by house flies. 4. Improve biological control techniques for filth flies. 4A. Improved efficacy of Beauveria bassiana by formulating combination products with other agents. 4B. Location of host pupae by filth fly parasitoids. 4C. Improve the quality of commercially available fly parasitoids.

Approach:
Objective 1 will investigate and identify methods for management of house flies under the higher temperatures expected to occur with global warming. It will also use trapping data to determine risk of introduction of exotic Stomoxys spp. in the U.S. Objective 2 will develop chemical or optical attractants that will enable traps for stable flies to become more efficient and capture greater numbers of flies. It will also adapt behavior-altering devices, such as pesticide-impregnated fabrics, for different uses, such as attract and kill devices. Objective 3 will evaluate new methods for determining the presence of sub-surface immature fly populations in field habitats. It will also further develop methods to allow house flies to spread selected IGRs throughout their habitats. Objective 4 will improve the efficacy of a biological control agent by formulating it with other selected lethal agents. It will also investigate the methods (e.g., chemical cues) used by parasitic wasps to locate fly pupae in field habitats. Finally, we will gain new knowledge on the effects of long-term colonization on the performance of parasitic wasps being released into the field.
