Phys.org reports, "Mediterranean fruit flies, an agricultural pest, have been modified in a lab experiment so more males are born than females, reducing their numbers.
"The experiments suggest that the modification could be developed for use in a range of other agricultural pest species, or insects that carry human diseases.
"Agricultural pests like the Mediterranean fruit fly, or medfly (Ceratitis capitata), cause significant crop losses, so finding new ways to tackle infestations is crucial for feeding a growing global population.
"The study, carried out by researchers at Imperial College London and the Hebrew University of Jerusalem, is published in BMC Biology."
