Hypothesis
When do Anopheles gambiae individuals deposit eggs during the day and night?
Conclusion
Anopheles gambiae mosquitoes lay most of their eggs shortly after dark, but can oviposit at any time if they have access to a suitable substrate.
Supporting Evidence
- Caged laboratory strain A. gambiae deposited 65% of their eggs between 1800 and 0 h.
- House-collected A. gambiae groups laid 74% of their eggs between 1800 and 200 h.
- Individual A. gambiae females laid eggs over a continuous 2–4 h period without interruption.
Takeaway
Anopheles gambiae mosquitoes usually lay their eggs at night, but they can also lay eggs during the day if they have a place to do it.
Methodology
The study used modified wall clocks to measure egg deposition by caged mosquitoes over a 24-hour period.
Potential Biases
Potential bias from using only laboratory strains and specific environmental conditions.
Limitations
The study was conducted in controlled laboratory conditions, which may not fully represent natural environments.
Participant Demographics
The study involved caged laboratory-reared and house-collected Anopheles gambiae mosquitoes.
