Fruit flies are beginning to build a resistance to common insecticides including the world’s most used insecticide imidacloprid.

The study led by academics from the University of Melbourne found fruit flies living in south-eastern parts of the country, including Victoria, New South Wales, and South Australia are evolving to resist the effects of sprays.

Dr. Fournier-Level says agribusinesses need to look at genetic and ecological factors to manage the pest.
