Latest Research on Exotic Pests

Launched in 2001 and administered by the UC Statewide IPM Program, EPDRP funds projects to address exotic pests and diseases, and invasive species in agricultural, urban, and natural environments.

The latest research on exotic invaders was released at the University of California Exotic/Invasive Pests and Diseases Research Program (EPDRP) Workshop.

From the glassy-winged sharpshooter that can cause Pierce’s disease of grapes and oleander leaf scorch, to fire ants that have infested residential areas in southern California, scientists funded by UC EPDRP are a step ahead in finding ways to prevent, detect, and control or eradicate these and other invaders.

Since its inception, the USDA-supported project has funded more than 100 studies, allocating nearly $9 million. The EPDRP is a collaboration between the UC Riverside Center for Invasive Species Research and the UC Statewide IPM Program, with funding from United States Department of Agriculture-Cooperative State Research, Education, and Extension Service.

The workshop was part of the Riverside campus’s 2006-2007 100th anniversary celebration of the contributions of the Citrus Experiment Station to pest and disease management.

Some highlights included: Entomologist Alex Gerry discussing the role of arthropods in the spread of exotic Newcastle disease in southern California; Weed scientist Marie Jasieniuk talking about how she used molecular markers to identify the origin and spread of herbicide resistance in weeds infesting California rice fields; Entomologist Elizabeth Grafton-Cardwell discussing an educational program that she and her research team developed to help identify and prevent the spread of the Asian citrus psyllid; Entomologist Les Greenberg presenting his flight studies of the red imported fire ant.
