Pacific Northwest Insect Management Handbook -- This handbook is updated annually and provides control recommendations for a wide range of agricultural pests. Navigate through the online version by selecting the chapter of interest from the drop-down list at top left. Spotted wing drosophila is featured in the 2011 Emerging Pest chapter. Control recommendations are made in the Small Fruit and Tree Fruit chapters.
Prevention - This is only effective if the pest has not made it to the targeted area. Use sanitation practices to destroy fruit culls. Remove other potential SWD habitat. Promptly remove all non-marketable hanging fruit from your fields. An ounce of prevention is worth a pound of cure.
We've compiled a list of the most frequently-used resources, reports, and bulletins used by growers and other affected by SWD.
