Integrated PestManagementMosquito and vector control is based on scientifically planned management tactics andcontrol strategies that reduce the abundance of target pests in a timely manner. This method iscommonly referred to as “integrated pest management” (IPM). This comprehensive programincorporates five basic methods: public information and education, mosquito and vectorsurveillance, biological control, physical control, and microbial and chemical control.One goal of the wild bird surveillance program is togain a better understanding of the local West Nilevirus infection cycle.Ticks are an area of concern in Sacramento and YoloCounties.In 2011, the District attended 32 public outreachevents.Public Information & EducationThe District’s outreach program educates and informs the public about mosquito and WNVprevention methods through an extensive advertising and media campaign. District messagesare also disseminated to the public by participating in a variety of community events, healthfairs, presentations to schools and community organizations as well as partnerships with localgroups.Mosquito & Vector SurveillanceThe District closely monitors mosquito activity, climate change and arbovirus activity by testingmosquitoes, sentinel chickens and wild birds for the presence of a pathogen, parasite orarbovirus. This research and surveillance information helps guide efficient control of vectorsand vector-borne diseases in Sacramento and Yolo counties.Biological ControlBiological control is the use of specially chosen living organisms to control a particular pest.This chosen organism might be a predator, parasite, or pathogen which will attack the harmfulinsect resulting in a desired reduction of pest population levels. The most common biological toolagainst immature mosquitoes in California are mosquito-eating fish such as the mosquitofish,Gambusia affinis, the Guppy, Poecilia reticulata, and the Threespine Stickleback, Gasterosteusaculeatus. When introduced to a mosquito breeding source, these fish quickly adapt, multiplyand become numerically capable of sustaining an effective control level.Physical ControlPhysical control (environmental manipulation) is achieved by altering the major ecologicalcomponents of the pest’s environment such as: promoting effective drainage, controllingemergent vegetation, promoting appropriate timing of irrigation, and encouraging mosquitoreduction best management practices in urban, agricultural, and conservation areas. Bymanipulating breeding sources, opportunity for pests to reproduce is eliminated.Microbial & Chemical ControlMicrobial and chemical control is the prudent use of specific microbials and chemicalcompounds (insect growth regulators and insecticides) that reduce mosquito populations. Thesematerials are applied when other methods are unable to maintain mosquito numbers below alevel that is considered tolerable or when emergency control measures are needed to rapidlydisrupt or terminate the transmission of disease to humans and animals. These products andapplication methods used are registered for public health use by the California Departmentof Pesticide Regulations and are designed to minimize non-target effects. Larvicides targetmosquito larvae and pupae; adulticides are chemicals that reduce adult mosquito populations.4 Sacramento–Yolo Mosquito & Vector Control District
Public Information& EducationThe District’s award winning public information and education department strives to raiseawareness of mosquitoes and of vector-borne diseases such as WNV, Western EquineEncephalomyelitis (WEE), St. Louis encephalitis (SLE), canine heartworm, malaria, Babesiosisand Ehrlichiosis. This is done through extensive media coverage obtained on television, radio,print and various news websites using an aggressive advertising campaign which includesradio and television advertisements in English and Spanish, print ads in various languages,outdoor creative ads and online interactive web ads. The District’s media strategy also includesparticipation in various radio and television public affairs shows and television programs usedto disseminate District messages. Two additional elements important to the department arecommunity outreach and the school program. The District hosts information booths at severalcommunity events throughout Sacramento and Yolo counties where educational materials aredisseminated and the public receives information about available District services. Anotherelement of outreach is the school program which includes year round classroom presentationsand an annual spring Design a Calendar Page Contest for all students and schools withinSacramento and Yolo counties.All community members are encouraged to prevent mosquitoes and West Nile Virus bypracticing the DISTRICT D’S of Mosquito Prevention. DRAIN any standing water that mayproduce mosquitoes. DAWN and DUSK are times to avoid being outside. These are the timeswhen mosquitoes are most active. DRESS appropriately by wearing long sleeves and pants whenoutdoors. DEFEND yourself against mosquitoes by using an effective insect repellent, such asDEET, Picaridin or Oil of Lemon Eucalyptus. Make sure you follow label directions! DOOR andwindow screens should be in good working condition. This will prevent mosquitoes from enteringyour home. DISTRICT personnel are available to address any mosquito problem you may beexperiencing by calling 1-800-429-1022 or visiting us online at www.FIGHTtheBITE.net.Winners in the annual Fight the Bite Calendar Page Contest for Sacramento and Yolo counties for all studentsin grades K-12.Community EventsAttended in 2011California State Lottery Health and Safety FairCaltrans Health and Wellness FairCitrus Heights Sunday FundayCity of Sacramento Earth DayCity of Sacramento Neighborhood SummitCHP Transportation and Wellness FairCostco Health & Safety FairCourtland Pear FairDavis Picnic DayDMV Awareness Expo and Health FairElk Grove Harvest FestivalFarm Bureau Health FairFestival de la FamiliaFolsom Family ExpoFoulks Ranch Health FairFranchise Tax Board Health and Safety FairGalt 4th of July FestivalGalt Strawberry FestivalHarvest FestivalNutrition and Health Week at the Mexican ConsulateOrangevale/Fair Oaks Community MeetingPacific Rim Street FestivalRancho Cordova Kids dayRivercats Fight the Bite NightSacramento County FairSacramento County Farm Bureau Health FairSenior Awareness DaySMUD Safety FairSOAR Senior Health FairState Wellness FairWinters Youth DayYolo County Fair2011 Annual Report5
