Research Project: Development of Sustainable Fly Management Tools in an Era of Global Warming

Location: Mosquito and Fly Research

Project Number: 6036-32000-049-02-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Oct 1, 2014
End Date: Jun 30, 2018

Objective:
1. Develop autdissemination technology for the insect growth pyriproxyfen against house fly and to determine its compatibility with parasitoids. 2. Determine likely effects of rising temperatures on flies and parasitoids, identify heat-tolerant strains of biological control agents, and re-launch a simulation model of fly management that takes climate change into account.

Approach:
Objective 1, Pyriproxyfen: The relative susceptibility of house flies and parasitoids will be determined in the laboratory; data will be analyzed by probit analysis to determine the LC90s for flies and several candidate parasitoids. An autodissemination station will be developed and tested in outdoor cages under a range of environmental conditions in both countries. Field tests will be conducted using the most promising station design. To be conducted by both ARS and Israeli investigators. Objective 2, Climate change: Flies and parasitoids will be subjected to selection pressure under rising temperature conditions for 20 generations to determine the relative genetic plasticity of each. Parasitoids will be colonized from both moderate and high temperature locations to identify heat-tolerant strains for use in hot locations. Data from these experiments will be used to update temperature-dependent modules in a legacy simulation model of fly management. A new version of the model will launched and hosted on a USDA website. To be conducted by both ARS and Israeli investigators.
