Location: Invasive Species and Pollinator Health
Project Number: 2030-22000-029-19-S
Project Type: Non-Assistance Cooperative Agreement
Start Date: Sep 15, 2016
End Date: Sep 30, 2020
Develop collaborative research efforts on biological control, pest management and pollinator health research activities. To provide sampling of aquatic weed growth under field and controlled climate conditions in cooperation with USDA scientists. To monitor environmental characteristics (nutrient and water conditions) that affect weed growth in the Delta and conduct collaborative research on bagrada bug by facilitating colony development and maintenance. Finally collaborate on pollinator health research activities that facilitate the colocation and initiation of new research team.
The USDA Exotic and Invasive Weeds Research Unit and University of California Davis Department of Entomology and Nematology team will continue collaborations on rearing bagrada bug and other pentatomid species that can be used for host range testing. Lab colonies will be made available to cooperators and methods for improving overwintering colony persistence will be shared. Rearing methods and advances in colony maintenance will be developed. This effort will ensure that both parties are able to depend on each other to bolster lab colonies when individuals are limiting. Collaborations on weed biological control activities will also continue. Processing and analyzing plant nutrients will be conducted to test the relevance of this parameter on herbivore densities attacking water hyacinth in the Sacramento – San Joaquin River Delta system. Collaboration on field work, including piloting boat trips and coordinating sample processing will be accomplished. Abiotic variables driving weed growth and development (such as air and water temperature, nutrient levels, etc.) will be assessed and used to predict herbivore dynamics in critical habitats. Research on pollinator health will be initiated, facilitating a collaboration between new USDA scientists and the Department. Together, research personnel, operational staff, local land and waterway managers, and county parks will be planning and working together throughout this project. Outcomes will be evaluated and promoted in cooperation with the University of California (UC) Cooperative Extension Service specialists. Program enhancements will thus be directly transferred to end-users as the program advances through direct application and assessment.
