Pierce's Disease Control Program Maps
Areawide Trapping
GIS is used as a decision support tool in the areawide management of glassy-winged sharpshooter (GWSS) in California. Traps are located using GIS/GPS, and then serviced using portable data terminals. Trapping data is uploaded to a central server, allowing areawide managers to determine GWSS hotspots over large areas in Tulare, Kern, Ventura, and Riverside counties. Weekly maps show where GWSS have been found in single cycles of trap servicing, and the summary maps show cumulative counts for the year.
Interactive Map
This is an internet map server application which reports the location of GWSS finds, and shows the distribution of those finds relative to established GWSS infested areas, urban areas, riparian areas, nurseries, crops of concern to the management of Pierce’s Disease including: grapes, citrus, almonds, olives, stonefruit, alfalfa, and avocados; and other features of concern. It also shows the locations where biological control agents have been released in an effort to reduce GWSS populations. The site also enables users to identify if an address is inside or outside a GWSS-infested area using geocoding.
Infested Areas
These are areas subject to program regulations because of the presence of the glassy-winged sharpshooter. There are overviews of current and eradicated infested areas throughout the state, and maps that are designed to clearly show the boundaries of the infested areas for the partially infested counties.
