Field Trials of Fenvalerate and Acephate to Control Spruce Bud Midge, Dasyneura swainei (Diptera: Cecidomyiidae)

John Hard, Patrick Safranyik, Edward Holsten

Only the highest concentration of fenvalerate (0.025 percent), which is currently registered with the United States Environmental Protection Agency for forest use, provided significant protection.
