Project Number: 6066-22320-009-000-D
Project Type: In-House Appropriated
Start Date: Dec 22, 2015
End Date: Sep 30, 2019
Objective 1: Discover new efficacious natural products, including fire ant-specific pathogens, for Integrated Pest Management (IPM) of invasive ant species. Sub-objective 1A: Evaluate naturally occurring toxins for invasive ant control. Sub-objective 1B: Evaluate entomopathogenic agents for invasive ant control. Objective 2: Determine gene function and utilize existing genomic resources to develop gene disruption approaches for mitigating the impact of invasive ants. Sub-objective 2A: Perform database comparisons to identify candidate genes for disruption. Sub-objective 2B: Functionally characterize specific candidate genes targeted for disruption. Objective 3: Improve existing and design new biopesticide delivery systems as part of Integrated Pest Management (IPM) programs for invasive ant species. Sub-objective 3A: Enhance the efficacy of biopesticides by improving adjuvants and synergists.
Current practice for controlling invasive pest ants depends heavily on synthetic insecticides, which have hazardous impacts beyond their intended uses. New safer and more sustainable technologies are needed to improve pest ant management. This project plan describes research to develop new products for managing invasive ants, particularly the imported fire ant, Solenopsis invicta, and the tawny crazy ant, Nylanderia fulva. This research will focus on 1) identifying new biopesticides, including naturally occurring toxins and biological control agents; 2) identifying and characterizing targets and methods for gene disruption; and 3) developing and improving delivery systems to maximize the efficacy of newly developed and existing biopesticides. This research will produce innovative products and methods for managing invasive pest ants.
