Releasing genetically-modified mosquitoes into the wild to fight malaria, Zika or other insect-borne diseases is premature and could have unintended consequences, researchers said in a new report.
"Our committee urges caution -- a lot more research is needed to understand the scientific, ethical, regulatory and social consequences of releasing such organisms," said Arizona State University professor James Collins, who was co-chair of a National Academies of Sciences, Engineering and Medicine committee.
The committee was studying gene drives -- systems of "biased inheritance" that make it more likely for a genetic trait to pass from parent to offspring.

With new gene-editing techniques, modifications can quickly spread through a population via a gene drive, greatly increasing chances that the altered gene will become widespread.
"Preliminary research suggested that gene drives developed in the laboratory could spread a targeted gene through nearly 100 percent of a population of yeast, fruit flies or mosquitoes," the academies said in a news release announcing the committee's report Wednesday.
The technology could potentially be used to target wild mosquitoes, modifying them so they are not able to carry or spread infectious diseases such as dengue, malaria and Zika.
