Hypothesis
Can indoor residual insecticide spraying effectively control malaria vectors on Bioko Island?
Conclusion
The intervention successfully controlled all three malaria vectors once an effective insecticide was used.
Supporting Evidence
- 2,807 Anopheles funestus and 10,293 Anopheles gambiae s.l. were captured during the study.
- After the third spray round, no infective mosquitoes were identified.
- Sporozoite rates were significantly reduced after the first spray round.
Takeaway
The study shows that spraying insecticide inside homes can help stop mosquitoes that spread malaria.
Methodology
Mosquitoes were captured using window traps at 16 sites and analyzed for species identification and infection rates.
Limitations
The study did not assess long-term effects beyond the two-year monitoring period.
Participant Demographics
The population of Bioko Island is estimated at 250,000, mostly living in or around Malabo.
