The Riverside County Vector Control Program conducts Mosquito population studies throughout the year.
New Jersey light traps have been stationed in the western portion of Riverside County and in the unincorporated areas around the City of Blythe. Depending upon the time of year, contents of the traps are collected either biweekly or weekly, and mosquitoes are analyzed as to the type and abundance. The light traps play an important role in determining the abundance of mosquitoes known to be involved in virus transmission and help technicians in locating mosquito-breeding sites.
When positive results from our Departments surveillance activities occur, our Department works closely with the California Department of Public Health to implement a "Response Plan". The Response Plan outlined by the State is dependent upon many variables such as environmental conditions, adult mosquito abundance, mosquito species involved, the occurrence in sentinel chickens and/or wild birds, geographical location, any human cases, and other pertinent information. Portions of the plan being implemented may include, but are not limited to, one or more of the following: Increasing public education; accelerated mosquito control (adulticiding and larvaciding); alerting physicians and veterinarians; coordinating with the local Office of Emergency Services; and other activities as appropriate.
