We need your help to prevent the spread of the Asian Citrus Psyllid. Please don’t move citrus trees, or their trimmings, from an area where the psyllid has been found to an area where the pest has not been detected. Please call the Plant Services Division of the Arizona Department of Agriculture for more information. In Yuma call (928)341-1680 for all other areas please call (602)542-0955.
The Asian Citrus Psyllid (ACP), an aphid-like insect, is a serious pest of all citrus and closely-related plants because it can transmit the disease huanglongbing, or Citrus Greening (HLB), when it feeds on the plants’ leaves and stems. HLB is the most devastating disease of citrus in the world. Symptoms of HLB include yellow shoots, leaf mottle, small upright leaves and lopsided fruit with a bitter flavor. Infected trees decline in health, produce inedible fruit and eventually die. There is no cure for the disease and infected trees must be removed and destroyed to prevent further spread of HLB.
