Female mosquitoes, which feed on human blood to obtain iron and amino acids required to produce eggs, are notorious for transmitting viruses responsible for deadly diseases, such as yellow fever, Dengue, and Zika. Over the years, researchers have devised various solutions, ranging from repellents to vaccines to genetic engineering, to combat the vectors. Now, a team at New York's Rockefeller University has come up with a unique solution to fend off the dangerous insects - filling their little bellies with diet drugs to curb their appetite for human blood.
