Cornell Research Reveals Spotted-wing Drosophila Life Cycle

Scientists at Cornell University have published research showing what spotted-wing drosophila adults and larvae eat, and where they lay their eggs. The study found that when fruit is not in season, the insect pest successfully lays eggs and develops early in the season on mushrooms, late in the season on rotting apples, and on complex bird manures. The insight could help growers control pest populations by managing non-fruit-season food sources, which is important because the flies can live for a full year, with a female laying up to 400 eggs per month in non-fruit food sources in early spring.
