Hypothesis
Can new acylpiperidine compounds provide a more effective and safer alternative to DEET for repelling mosquitoes?
Conclusion
The new acylpiperidine compounds lasted significantly longer than DEET in repelling mosquitoes.
Supporting Evidence
- DEET treatment wore off after 17.5 days on average, while several test compounds lasted 40 to 50 days.
- One of the new compounds remained active for 73 days.
Takeaway
Scientists are testing new mosquito repellents that last much longer than the common one called DEET, which can cause skin problems.
Methodology
The mosquito-repelling potency of each compound was tested by volunteers who put their arms inside boxes filled with mosquitoes for 1 minute per compound per day.
Limitations
The long-term safety and effectiveness of the new compounds against malaria-carrying mosquitoes have yet to be evaluated.
Participant Demographics
Volunteers tested the compounds by exposing their arms to mosquitoes.
