Residential ACP Management Strategy
The Asian citrus psyllid (ACP) is widely established in both commercial and residential citrus throughout Southern California. Large-scale eradication of ACP in these environments is not feasible. Rather, the goal is to reduce psyllid populations to slow the establishment and spread of Huanglongbing (HLB) disease. In 2016-17, the number of HLB-infected trees started to rapidly increase. More than 500 HLB-infected trees have been found in residential Los Angeles and Orange counties and a small number of trees in Riverside County. These trees have been removed, but there are likely more out there that contain the disease. Homeowners can help by reporting trees they suspect have the disease and if they are in a community where HLB-infected trees have been found, to consider removing their citrus trees.
