Summary
Mosquito biting rates and repellent effectiveness vary with the menstrual cycle. Mosquitoes are more attracted to hosts during ovulation, reducing repellent protection time.
Area of Science:
- Entomology
- Human Physiology
- Medical Science
Background:
- Mosquito-borne disease control relies on understanding host attractiveness.
- Variability in mosquito biting rates among humans is significant.
- Factors influencing within-individual host attractiveness remain under-explored, particularly the menstrual cycle.
Purpose of the Study:
- To investigate the relationship between the human menstrual cycle and mosquito host attractiveness.
- To assess the impact of the menstrual cycle on the efficacy of topical mosquito repellents.
Main Methods:
- Observational study comparing mosquito landing rates and repellent protection times across different phases of the menstrual cycle.
- Controlled experiments to quantify host attractiveness variations.
Main Results:
- Mosquito landing rates were significantly higher during the ovulation phase compared to menstruation and the luteal phase.
- Topical repellent protection time was shorter during ovulation.
Conclusions:
- The menstrual cycle influences human attractiveness to mosquitoes.
- Ovulation represents a period of increased attractiveness, reducing repellent efficacy.
- Findings inform strategies for mosquito-borne disease prevention and personal protection.
