UCLA scientists and colleagues identify structure of a molecule that kills mosquitoes carrying malaria and West Nile

Five UCLA researchers were part of an international team that has used X-rays to reveal the structure of a molecule that is toxic to disease-carrying mosquitoes. The findings move the scientific world one step closer to genetically engineering a toxin that would be lethal to species that carry dengue fever and the Zika virus. (more…)

Making Blood-Sucking Deadly for Mosquitoes

*Inhibiting a molecular process cells use to direct proteins to their proper destinations causes more than 90 percent of affected mosquitoes to die within 48 hours of blood feeding, a UA team of biochemists found.*

Mosquitoes die soon after a blood meal if certain protein components are experimentally disrupted, a team of biochemists at the University of Arizona has discovered.

The approach could be used as an additional strategy in the worldwide effort to curb mosquito-borne diseases like dengue fever, yellow fever and malaria. (more…)

Low-income neighborhoods appear to be the most susceptible to West Nile virus, a mosquito-transmitted disease that is linked to more than 1,000 deaths since in the United States since 1999, according to new UCLA-lead research.

Using data on infected humans and mosquitoes from the West Nile virus hotspot of Orange County, Calif., from 2005-08, scientists found that per-capita income and other economic conditions were the single greatest predictor of occurrence, explaining 85-95 percent of the variation. While economic conditions have previously been linked to disease, the study is the first to use a rigorous statistical model. (more…)
