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. Mosquito Immature Habitats ► Agricultural ► Industrial ► Domestic ► Natural

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 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? Flight Range DistanceSpecies Short Few blocks to a mile Culex pipiens Oc. sierrensis Medium 3 to 10 miles Culex tarsalis Long 10 to 40 miles An. freeborni Oc. melanimon

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?”
