Hypothesis
Does blood feeding affect the susceptibility of Aedes aegypti to the entomopathogenic fungus Metarhizium anisopliae?
Conclusion
Blood feeding reduces the susceptibility of Aedes aegypti to fungal infection temporarily, returning to normal levels after about 96 hours.
Supporting Evidence
- Blood feeding significantly altered survival rates of Aedes aegypti.
- Susceptibility to fungal infection returned to normal levels after 96 hours post-blood feeding.
- Both Rockefeller and wild strains showed reduced survival rates when exposed to fungi after blood feeding.
Takeaway
When mosquitoes eat blood, they become less likely to get sick from a certain fungus for a little while, but then they go back to being normal.
Methodology
Female Aedes aegypti were infected with two fungal isolates using an indirect contact bioassay, and survival rates were monitored post-blood feeding.
Potential Biases
Potential bias in the selection of mosquito strains and environmental conditions during experiments.
Limitations
The study only tested two fungal isolates and did not explore other potential factors affecting susceptibility.
Participant Demographics
Adult female Aedes aegypti mosquitoes from Rockefeller and wild strains.
