Genetic methods to reduce Aedes aegypti mosquito numbers
Advancing CRISPR-Based Genome Editing Strategies for managing Aedes aegypti mosquito populations
This project uses gene-editing tools to try to lower Aedes aegypti mosquitoes that spread dengue, Zika, chikungunya, and yellow fever for people in affected communities.

What this research studies
Researchers will develop CRISPR-based approaches including a sterile-male technique (pgSIT) that produces only sterile males and gene-drive systems that can spread engineered traits through mosquito populations. Most work will be done in the lab and in controlled experiments to measure how well these tools work and to study safety, containment, and how they behave over time. The team will refine molecular designs, run population models, and test strategies to limit unintended spread before any consideration of field release.
Who could benefit from this research
Good fit: Communities and people living in regions where Aedes aegypti spread dengue, Zika, chikungunya, or yellow fever would be the ones most likely to benefit.
Not a fit: People whose health problems are not caused by Aedes-transmitted viruses or who need immediate clinical care would not directly benefit from mosquito-focused genetic control.
Why it matters
Potential benefit: If successful, these approaches could greatly reduce the number of disease-carrying mosquitoes and lower infections, hospitalizations, and deaths from Aedes-transmitted viruses.
How similar studies have performed: Related laboratory studies have shown promising results with CRISPR-based suppression and modification in mosquitoes, but broad field success and long-term ecological safety are still unproven.
