In 2011 Monsanto, the maker of herbicides and genetically engineered seeds, bought an Israeli company called Beeologics, which had developed an RNA interference technology that can be fed to bees through sugar water. The idea is that when a nurse bee spits this sugar water into each cell of a honeycomb where a queen bee has laid an egg, the resulting larvae will consume the RNA interference treatment. With the right sequence in the interfering RNA, the treatment will be harmless to the larvae, but when a mite feeds on it, the pest will ingest its own self-destruct signal.
The specificity and precision of topical RNA interference could be used for other agricultural tricks, including perhaps making weeds once again sensitive to a Monsanto herbicide that they have developed resistance to.
