Fresno County Agricultural Commissioner, Les Wright, in cooperation with
the California Department of Food and Agriculture (CDFA) and the United States
Department of Agriculture (USDA), announces that an extensive survey and
treatment program has begun in response to the detections of Asian citrus
psyllid (ACP) near the city of Dinuba in Tulare County.
The recent find in Dinuba is of great concern since 100s of live adults and
nymphs were found on nearby trees in the neighborhood. This is the first time
live ACPs have been observed on host plants in the San Joaquin Valley. There is
now real evidence that there has been a breeding population of the ACP in the
All host plants will be treated within 800 meters of
the find; residents within the treatment area will be notified in advance. CDFA
will soon establish a quarantine for all citrus plants and fruits within five
miles of the find to prevent the movement of host material that may be
affected. The prohibition of movement of host plants and fruits will apply to
both the homeowner and the commercial citrus grower.
quarantine boundary will extend into Fresno County as far as the city of
Reedley. The Fresno County Department of Agriculture is cooperating with the
project to ensure that host trees and fruits are not removed from the area
under the proposed quarantine.
ACP is a dangerous pest of citrus. The Fresno County
Department of Agriculture is in the process of determining the full extent of
this incident to protect the state's vital citrus industry, as well as backyard
citrus trees. It must be emphasized that citrus fruit is safe to eat and the
disease is not harmful to human health.
Homeowners should be aware that they will also be
under the forthcoming quarantine order. If someone needs to move host fruit or
trees, including pruning and trimmings, they should contact the project to find
out how to properly handle them.
This pest is of grave concern because it can carry the
disease huanglongbing (HLB). All citrus and closely related species are
susceptible hosts for both the insect and the disease.
There is no cure once a tree becomes infected. The
diseased tree will decline in health and produce bitter, mis-shaped fruit until
it dies. To date- HLB has only been detected in one backyard tree and one
psyllid in the Hacienda Heights neighborhood of Los Angeles County.
Residents in the area who think they may have seen the pest are urged to
call the Pest Hotline at 800-491-1899. For more information on the Asian
citrus psyllid and huanglongbing disease visit: http://www.cdfa.ca.gov/plant/acp/.
