Daniel and Kelly’s Extraordinary Universe How do we control mosquito populations?
Dec 4, 2025
Katrina Whiteson, a biologist and professor, joins the discussion to dive into mosquito biology and control methods. They explore how mosquitoes detect us through CO2, scents, and heat. Katrina explains innovative strategies like the sterile insect technique and Wolbachia, a bacteria that blocks viral replication. The conversation also touches on the implications of GMO releases and gene drives using CRISPR, alongside the ethical concerns and ecological risks involved. It's a fascinating look at the battle against these pesky bloodsuckers!

Episode notes
Estimate Mosquito Numbers With Marked Releases
- Use fluorescent dust or genetic markers on lab-reared males to estimate wild mosquito population proportions.
- Attract and recapture mosquitoes with CO2 baited traps, then count marked vs. unmarked to infer population size.
Sleeping Under Bed Nets In Tahiti
- Daniel described sleeping under bed nets in Tahiti and waking up bite-free, then using a net at home for weeks.
- He noted nets can effectively suppress mosquito bites and felt personally protected.
Eliminate Standing Water Regularly
- Remove or regularly empty standing water around homes to interrupt mosquito breeding.
- Refill birdbaths and outdoor containers every day or two to prevent eggs from developing into adults.
