Annual Reports2004—Competitive Grants Programs
Summaries of research projects are online. Funded projects (below) are linked to the summaries.
Two years of budget cuts to UC IPM, totaling almost $500,000, have drastically reduced the amount of funds available for new research grants. However, UC IPM officials have released a request for proposals for new projects for 2005-06. In 2004-05, continuing projects exhausted most of the available funds, but the program was able to fund one year of four of the projects that had been approved, but not funded, for 2003-04. Mike Rust, Entomology, UC Riverside, stepped down as Associate Director for Research in 2003. This position has not been refilled, and for now will continue to be vacant since the UC IPM grants program has been significantly reduced. If the grants program can be rebuilt, an associate director for research will be appointed.

Summaries of research projects are online. Funded projects (below) are linked to the summaries. The UC Exotic/Invasive Pests and Diseases Research Program (EPDRP) is funded through a Special Research Grant provided through USDA-CSREES. The review committees approved $1.7 million in funding for 23 new projects from the 2004-2007 USDA grant. This brings the number of projects sponsored by the program to 65, for almost $6 million. The third annual research workshop sponsored by Exotic/Invasive Pests and Diseases Research Program was held at Emeryville, California, Oct. 13 and 14, 2004. Earlier this year, the program co-sponsored the Glassy-winged Sharpshooter Conference in Napa. Established in 2001, the UC Exotic/Invasive Pests and Diseases Research Program is a joint program of the UC Riverside Center for Invasive Species Research and UC IPM. The program, which targets research on exotic pests and diseases/invasive species important to California, aims not only to improve our knowledge of pests that are already in California, but also to get a head start on pests that pose a likely threat to the state. Additional funds are being sought to extend the program and, if successful, the EPDRP will request new proposals late Winter 2005. For more information about the program and the projects it sponsors, see the UC IPM Web site.
