  • OSU Extension Set to Release Tiny Wasp That Targets Destructive Fruit Fly

    • Jun 6, 2022
    • Oregon State University.

    • After 12 years of research, a parasitic wasp that controls a highly destructive fruit fly will be released by Oregon State University agricultural scientists in June. Vaughn Walton, Extension entomologist and professor in the College of Agricultural Sciences, said the U.S. Department of Agriculture has permitted release of the wasp (Ganaspis brasiliensis), a slow process that took more than 10 years from application to decision. Now that it has a permit, Walton’s lab, which is part of the OSU Agricultural Experiment Station, is raising enough wasps to make a dent in the spotted wing drosophila (SWD) population in Oregon.

  • Natural Enemy of Invasive, Berry-Eating Fly Found in U.S.

    • A parasitoid wasp that is the natural enemy of a fly known as the spotted-wing drosophila could be a good friend to growers. Washington State University researchers recently confirmed the discovery of the potentially beneficial wasp in the United States for the first time. The drosophila flies cause major damage to several Washington crops, especially sweet cherries and berries. The wasp, which lays its eggs in the flies, could be a means of controlling their spread.

  • The State of Integrated Pest Management for Spotted-Wing Drosophila

    • Sep 23, 2021
    • Entomological Society of America. Entomology Today.

    • Spotted-wing drosophila (Drosophila suzukii), is an invasive fruit fly species that causes about $500 million in economic damage to fruit crops in the U.S. each year. A native to southeast Asia, it arrived in the U.S. in Hawaii in the 1980s and in the continental U.S. in California in 2008. It is now widespread through many parts of the U.S. and the world. In a new review article published last week in the Journal of Economic Entomology, Vaughn Walton, Ph.D., of Oregon State University and a multi-university team of experts have created a comprehensive look at how SWD management strategies are evolving to address these challenges.

      The U.S. Department of Agriculture grant that funds part of Walton and colleagues SWD research stipulates that they work with industry influencers, and they have been doing this from the beginning. They bring technologies to industry and seek feedback on how well the technologies work in actual practice. "Federal funding is allowing us to listen to and serve our clients—the growers," Walton says. As the Journal of Economic Entomology paper details, many promising control strategies are being developed for this challenging and uniquely adaptable invasive species. With continued advances, researchers can hope that populations of SWD can be controlled and the damage they cause reduced.
