Damage to fruit by spotted wing drosophila (SWD) — an introduced pest from East Asia — is expected to increase this season. In response, Cornell researchers and extension educators have trap network covering some 30 counties around the state to keep tabs on the pest. (As of June 7, none have been reported.)
Growers and gardeners who want to stay up-to-date on the latest SWD monitoring, management options and more, can visit the new Spotted Wing Drosophila blog, managed by Juliet Carroll, Fruit IPM Coordinator for the New York State IPM Program.
The crops at highest risk for SWD infestation include fall raspberries, blackberries, and blueberries. June-bearing strawberries may escape injury, but late summer fruit or day-neutral varieties may suffer damage. Cherries, both tart and sweet, elderberries, and peaches are also susceptible. Thin-skinned grapes can be infested directly, though cracked or damaged berries are more susceptible.
