In Alameda County, the Vector Control District conducts mosquito surveillance and control only in the City of Albany—the Alameda County Mosquito Abatement District has the jurisdiction for the rest of the County.

Our District participates in the California Vector-borne Disease Surveillance System (CalSurv). CalSurv is managed jointly by the Mosquito and Vector Control Association of California, representing more than 65 local mosquito and vector control agencies in California, the California Department of Public Health (CA-DHS) and the Center for Vector-borne Diseases of the University of California at Davis. This is a State-wide surveillance system used to detect pathogen activity in vector populations.

West Nile virus (WNV): The two main mosquito species involved in the WNV transmission cycle in our area are Culex tarsalis and Culex pipiens and both species are found in Alameda County. In Albany, carbon dioxide baited traps are set overnight from April to October by our staff to collect female mosquitoes which are submitted for West Nile Virus and other arboviral disease testing. Since the District conducts mosquito surveillance in the City of Albany, our involvement in the WNV surveillance program includes picking up dead birds for the CA-DHS WNV "Dead Bird Surveillance" program and submitting mosquito pools for virus detection. To date, the District has not detected any WNV activity in Albany.

We have detected these mosquito species in Albany:
Culex erythrothorax Culiseta incidens
Culex pipiens Culiseta particeps
Culex stigmatosoma Ochlerotatus sierrensis
Culex tarsalis Ochlerotatus squamiger
Culiseta impatiens Ochlerotatus washinoi
Culiseta inornata
