Hypothesis
The study aims to evaluate the efficacy and wash resistance of PermaNet® 3.0 compared to PermaNet® 2.0 against insecticide-resistant Anopheles gambiae.
Conclusion
Unwashed PermaNet® 3.0 caused significantly higher mortality against pyrethroid-resistant Anopheles gambiae and Culex spp than PermaNet® 2.0 and the conventionally treated net.
Supporting Evidence
- Mortality rates of over 80% were recorded only with unwashed PermaNet® 3.0.
- Significantly more An. gambiae s.s and Culex spp were caught in control huts than with other treatments.
- The proportion of mosquitoes exiting the huts was significantly lower with the control than for the treatment arms.
Takeaway
The new PermaNet® 3.0 mosquito net works better than the older version against resistant mosquitoes, especially when it's not washed.
Methodology
The study compared the efficacy of washed and unwashed PermaNet® 2.0 and 3.0 against resistant mosquitoes in experimental huts over 12 weeks.
Limitations
The study did not measure blood feeding rates as a standard parameter due to ethical reasons.
Participant Demographics
Five adult male volunteers slept in the huts each night during the study.
