Genetically engineered moths could be released in Britain to prevent devastating damage to broccoli and kale crops, scientists have claimed.
Researchers from Oxford University spinoff Oxitec, have tweaked the genes of the insects so that they only produce male offspring.
Tests in greenhouses have shown that releasing GM diamondback or cabbage moths causes populations to crash quickly, limiting damage from caterpillars. New results show that levels had been controlled within just eight weeks.
Now scientists are set to carry out new outdoor trials in New York State after gaining approval from the US Department of Agriculture.
