1. Mosquito Biology Larval Control

2. General Points • Four development stages (egg/larva/pupa/adult) • Immature stages need standing water (egg/larva/pupa)

4. How long from egg to adult? • 3 to 5 days for flood water species like Aedes & Ochlerotatus • 7 to 10 days for standing water species like Culex • 14 to 21 days for rice field species like Anopheles

5. District Species • 53 California species • 7 genera, 24 District species • Different habitats, behavior, blood sources

7. Anopheles

8. Rice Fields/”Clean Water Sources”

10. Agricultural Industrial Domestic Natural Mosquito Immature Habitats

11. Mosquito Breeding Sites Around the Home/Community

15. Reporting of problems • Maybe no need to report! • If it can be drained, then problem goes away • District website • www.fightthebite.net • District phone • 1-800-429-1022 between 7:00-3:30 • Any way you can let us know!

18. When are Mosquitoes Active? • Dusk & Dawn (Culex & Anopheles) • Daytime (Aedes & Ochlerotatus)

19. How Long do Mosquitoes live? • Depends on season (winter/summer) and species • In summer 2-3 weeks • Ochlerotatus and Aedes longer lived than Culex.

20. How Far can a Mosquito Fly from a Development Site?

21. Mosquito Control • Water management (The Best!) • Biological control • Insecticides (larvicides, adulticides

22. Public Awareness and Education • Informing • What you can do to prevent mosquitoes • What you can do to protect yourself • Changing Behavior • “You poured out that bucket of water, but did you just fill it back up with the sprinkler?”
