Hypothesis
Are Aedes aegypti mosquitoes newly introduced in southern Arizona or have they been present at low levels until favorable conditions allowed their population to grow?
Conclusion
Aedes aegypti mosquitoes have reemerged in Arizona, raising concerns about potential dengue transmission.
Supporting Evidence
- Aedes aegypti was found in Tucson and Nogales after being absent for decades.
- Trapping data suggests that the mosquitoes may have been newly introduced.
- More than 400 cases of dengue fever were reported in the bordering Mexican state of Sonora in 1996.
Takeaway
Aedes aegypti mosquitoes, which can spread diseases like dengue, have been found in Arizona again after being absent for many years.
Methodology
Routine monthly mosquito sampling and trapping using CO2 traps and oviposition traps.
Limitations
Initial attempts to use oviposition traps were unsuccessful due to climate conditions.
Participant Demographics
