Using genetic techniques to target just one species of insect

Scientists and biotechnology companies are developing what could become the next powerful weapon in the war on pests — one that harnesses a Nobel Prize-winning discovery to kill insects and pathogens by disabling their genes.

By zeroing in on a genetic sequence unique to one species, the technique has the potential to kill a pest without harming beneficial insects. That would be a big advance over chemical pesticides.

“If you use a neuro-poison, it kills everything,” said Subba Reddy Palli, an entomologist at the University of Kentucky who is researching the technology, which is called RNA interference. “But this one is very target-specific.”
