“…Government-backed researchers in America are aiming to use virus-carrying insects to genetically engineer crops – raising fears the technology could be used for biological weapons.
A new article in the journal Science explores the shadowy program funded by the US Defense Advanced Research Projects Agency (Darpa).
The program aims to disperse infectious, genetically modified viruses that have been engineered to alter the chromosomes of crops – using insects to spread the viruses to the plants.
Researchers have budgeted more than $45m to pursue the genetic engineering scheme, in a program dubbed Insect Allies….”
The agency describes the research as a way to improve crop security: bugs like aphids, leafhoppers and whiteflies will be used to spread a virus to plants including corn and tomatoes, which will then impart beneficial genes making the plants resistant to disease or drought.
But in the Science article, an international team of scientists and lawyers warn that the technology could be put to more nefarious purposes, including military applications.
