The Asian Citrus Psyllid (ACP) is a small, aphid-sized insect that poses a serious threat to California's citrus trees. This invasive pest can carry and transmit a fatal bacterial disease called Huanglongbing (HLB) to all citrus species. HLB has already decimated citrus groves throughout Florida, costing the citrus industry millions of dollars. The psyllid is currently present in Southern California, but preventative measures can keep the disease and insect from spreading to California's citrus growing regions.

Asian citrus psyllid adults are 1/6 to 1/8 inch long with brown wings and red eyes. They feed on plants at a 45-degree angle, with their...
Invasive species are non-native plants, animals, or pathogens that can cause economic or environmental harm.

Stay tuned—we will be showcasing a different invasive species each day and where you can find more information.

The California Department of Food and Agriculture has declared a quarantine following the detection of Huanglongbing (HLB) in multiple residential citrus trees in Corona (Riverside County). This is the first time HLB has been detected in Corona.
The 107-square mile quarantine area will link up with the east side of the existing quarantine in Los Angeles, Riverside, Orange and San Bernardino counties, creating a contiguous 1,127-square-mile area. The new portion is bordered on the north by Chino Airport, on the south by Black Star Canyon, and on the east by Interstate 15.
The quarantine prohibits the movement of all citrus nursery stock or...
We hope by now most people have heard about and are aware of the Asian citrus psyllid (ACP), a small brown insect that carries a deadly citrus disease called huanglongbing (HLB), threatening all backyard citrus trees as well as the statewide citrus industry.
This insect feeds on newly developed leaves of all varieties of citrus trees and can spread the bacteria that causes HLB. The HLB disease can kill a citrus tree in as little as 5 years and there is so far no cure or remedy.
