- Invasive pests severely impact California agriculture
- Invasive pest challenges continue
- Ratings for pest status
- Many exotic and invasive pests are of major concern in California. The glassy‐winged sharpshooter (an insect) and purple loosestrife (a weed) are two invasive species that are established in some areas but still threaten to invade other areas.
- Invasive species of concern to California’s grape industry include European grapevine moth (EGVM) and light brown apple moth (LBAM), have not yet established themselves in all grape growing areas, but have already been costly to the state and the grape industry.
Ratings for pest status
Pests vary as to the potential and actual harm they present to California's agriculture; its environment and the general public.
Based upon the severity of harm, its economic impacts, and the degree of difficulty to manage such pests, a pest rating system is used nationally to rank agricultural pests. The rating that each pest is assigned will aid the county and state in determining the best course of action to take and prevent or control their establishment.
What can be done to stop the spread of exotic and invasive pests?
1. Don't bring foreign plant or animal material into California when you travel or spread species from local quarantine areas to non‐infested areas.
2. Learn to identify invasive species new to California. Contact your local UC Cooperative Extension office or Agricultural Commissioner for help identifying suspected invasive species or look at the UC IPM or CDFA Web site.
2. Report invasive species in your area. Contact your local UC Cooperative Extension office or Agricultural Commissioner to report invasives and to get information on controlling invasive species on your property. We will be successful in stopping bests by early detection and management before establishment.
