Pupa ' • • Mosquitoes need stagnant water to go through their life cycle. • Eggs can survive without water for several years and a will hatch when water is present, and conditions are = = right. Larva Invasive Aedes . 114 inch long • Not native to California Black and white bands across body • Aggressive day-time biters • • Breed indoors and outdoors IMPACTS TO ORANGE COUNTY 2016 = 3,500 acres or 5.0 sq miles .:■ r 2017 = 17,000 acres or 26 sq mile 2018 = 45,600 acres or 71 sq miles 2019 = 67,633 acres or 105 sq miles w 2020 = 89,666 acres or 140 sq miles Livable area of Orange County = _�. 320,000 or 500 sq miles 'Predictions use current data and reasonable assumptions that conditions will not change significantly in the future - MAINTAIN YOUR `--� DRAIN : Mosquitoes can develop in underground yard drains. ` PREVENTION : Add foam �. inserts or screens to the top of drains so mosquitoes L ,. T can't fly in ! Controlling for Aedes Mosquitoes Challenges of Invasive Aedes - • Have rapidly spread throughout California . ' • Found in every Y 9 city in Orange f County - • Prefer smaller water sources , making them harder to control • They lay their eggs in wateres sources in people's front yards, backyards, and patios • Areas where mosquito control IR agencies can't easily inspect �� What is SIT • Environmentally-friendly insect pest control method • A non-chemical control method • The basic steps of SIT are- • Sterilization of a target pest (mosquitoes), • Release of sterile males in a specific area over time • Sterile males will mate with wild females • The SIT technique results in no offspring and a declining pest population , reducing the presence of the specific breed of virus- spreading mosquitoes t; - 7i7'\ r Different SIT Techniques • Wolbachia : Wolbachia is a common type of bacteria found in insects . Approximately 6 in 10 of all types of insects, including butterflies, bees, and beetles , around the world , have Wolbachia. • Irradiation : Irradiation , such as with gamma rays and X-rays, is used to sterilize mass-reared insects so that, while they remain sexually competitive , they cannot produce offspring . • Genetically Modified Mosquitoes : GM mosquitoes are mosquitoes that have been implanted with a gene not originally present in the insect. In one case, a self-limiting gene that disrupts the normal processes of mosquitoes? offspring . J What you need to know • Male mosquitoes do not bite and can not transmit diseases • SIT will not eliminate the use of other chemicals to control fo mosquitoes . • SIT only targets one specific type of mosquito • Aedes aegypti • SIT releases will have to be ongoing every mosquito season • The District is evaluating the use of SIT and has not decided on a technique or when it would be used • SIT will not be widely implemented for several more years SIT in Orange County • District is exploring the use of irradiation in 2022 • NOW: SIT via irradiation is available to be implemented as soon as the mosquito colonies and equipment are available, no long regulatory process • PROVEN : This method is proven in other insects and more evidence is showing it works for Aedes mosquitoes • INITIAL RELEASE AREA: Approximately 300 Meter diameter or a quarter square mile SIT In Orange County Challenges • As biological organisms, it may take more or less time than estimated to establish a production colony. • Residents response to the project. • Extensive education program will be presented so that residents understand why they are seeing more male mosquitoes flying. • Distribution of the sterilized insects which may require additional staffing as the project expands. • Cost of SIT program.
