Molecular regulation of mosquito biting timing
Science Sessions are brief conversations with cutting-edge researchers, National Academy members, and policymakers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us.
In this episode, Laura Duvall introduces a potential pathway for disrupting the biting behavior of mosquitoes.
In this episode, we cover: •[00:00] Introduction •[00:57] Mosquito neuroscientist Laura Duvall introduces us to the normal biting behavior of mosquitoes. •[02:46] She tells why the biting behavior of the Aedes aegypti mosquito is of particular interest. •[03:24] Duvall describes findings regarding how mosquitoes' responses to CO2 vary over times of day. •[05:37] She introduces the PDF peptide that might be regulating timing of biting behavior and explains how losing that peptide changed mosquitoes' behavior. •[08:07] Duvall talks about the takeaways from the study for control of mosquito-borne illnesses. •[08:53] She lists the caveats and limitations of the study. •[09:26] Conclusion.
