Hypothesis
Does a microbe-free plant infusion stimulate egg hatching in Aedes aegypti?
Conclusion
Bacteria or compounds secreted by bacteria, rather than just low dissolved oxygen levels, stimulate the hatching of Aedes aegypti eggs.
Supporting Evidence
- 92.4% of eggs hatched in non-sterile infusion within 2 hours.
- 95.2% of eggs hatched in a 24-hour old bacterial culture.
- Only 4.0% of eggs hatched in sterile infusion.
Takeaway
Bacteria help mosquito eggs hatch, even when there's enough oxygen in the water.
Methodology
The study used non-sterile and sterile white oak leaf infusions and bacterial cultures to test egg hatching.
Limitations
The specific bacterial cues involved in hatching remain unidentified.
