Distribution of ACP, HLB and parasites in California
This zoomable map allows the user to see where and how often the Asian citrus psyllid (ACP) has been trapped since 2008 at the section level (one mile square). The sections where the beneficial Tamarixia parasites have been released are shown in green and Diaphorencyrtus parasite releases are shown in purple. The map can also show the current quarantine boundaries for huanglongbing disease (HLB), the movement of bulk citrus, and nursery stock.
