Nature Podcast These malaria drugs treat the mosquitos — not the people
May 21, 2025
Fredros Okumu, a malaria biologist at the University of Glasgow and Ifakara Health Institute, discusses innovative strategies for combating malaria. He highlights new compounds that can kill malaria-causing parasites within mosquitoes, potentially reducing disease transmission. This method could revolutionize malaria prevention, especially in communities facing insecticide resistance. Okumu also emphasizes the importance of field testing these groundbreaking approaches, offering hope for improved public health outcomes.

Episode notes
Mosquito Resistance Challenges Bed Nets
- Insecticide-treated bed nets lose efficacy as mosquitoes develop resistance.
- This resistance plateau in malaria reductions demands alternative control strategies.
Treating Mosquitoes for Malaria
- Targeting malaria parasites inside mosquitoes offers a novel disease control strategy.
- Killing the parasite in the mosquito prevents transmission without killing the mosquito itself.
Testing Compounds on Mosquito Parasites
- Test anti-parasitic compounds on live mosquitoes by applying them and then feeding mosquitoes infected blood.
- Assess parasite levels by dissecting mosquito guts after exposure to determine compound efficacy.
