Distribution of ACP, HLB and parasites in California
This zoomable map allows the user to see how many trap cards have had Asian citrus psyllids (ACP) since 2008 at the section level (one mile square area). In areas with low levels of psyllids (1-10 detections per square mile), local eradication programs are in place. In areas with higher numbers of psyllids (>50 detections per square mile) the psyllid is considered established and management programs are in place. The sections where the beneficial Tamarixia parasites have been released or found are shown in green, Diaphorencyrtus parasites are shown in purple. The map also shows the current ACP quarantine boundaries and the current huanglongbing disease (HLB) quarantine boundaries.
