Using CO2 to Fight Varroa Mites with Aakash Manaswi (398)

What if carbon dioxide could offer beekeepers another way to control Varroa mites? In this episode, Jeff Ott and Becky Masterman talk with award-winning high school researcher Aakash Manaswi, whose multi-year research project investigates using carbon dioxide (CO₂) as a treatment against Varroa mites. Aakash traces his interest in honey bees back to a childhood visit to an apiary, where a beekeeper explained how Varroa was affecting his colonies. That encounter eventually led Aakash to ask whether there might be another way to tackle the parasite.

Aakash explains the development of his CO₂ treatment prototype—a hive-top device that distributes carbon dioxide throughout a colony. His research progressed from laboratory testing of different CO₂ concentrations to prototype development and field trials comparing the approach with existing treatments. He discusses the 30% CO₂ concentration used in his research, treatment timing, effects on phoretic mites, and some of the important limitations that still need to be investigated.

The conversation also explores Aakash's AI-based system for counting Varroa mites on sticky boards, his work with mentors at 3M, USDA, and the University of Florida, and where he hopes to take the research next.

Aakash's work earned first place in Animal Sciences at the Regeneron International Science and Engineering Fair and the Peggy Scripps Award for Science Communication.

Before the interview, Jeff and Becky answer a listener question about another emerging tool for beekeepers: artificial intelligence. They discuss where AI can be genuinely useful—and why beekeepers should still question its answers, check its sources, and remember that sometimes the best answer in beekeeping remains, "It depends."
