Researchers in Norwich say releasing genetically-engineered fruit flies in the wild could be a cheap alternative to using pesticides.

Scientists at the University of East Anglia found increasing the male population by releasing the modified insects could reduce the overall population - making it a cost-effective and environmentally-friendly way to control pests.

Mediterranean fruit flies infest more than 300 types of fruits, vegetables and nuts.
