OSU updates resources for protecting bees from pesticides

 As the worldwide population of honey bees continues to decline, the Oregon State University Extension Service and partners have updated a tool for Pacific Northwest growers and beekeepers to reduce the impacts of pesticides on bees.

The revision of OSU Extension's publication appears after an estimated 50,000 bumble bees died in a Wilsonville parking lot in June. The Oregon Department of Agriculture confirmed in a June 21 statement that the bee deaths were directly related to a pesticide application on linden trees conducted to control aphids. The episode prompted the ODA to issue a six-month restriction on 18 insecticides containing the active ingredient dinotefuran.

OSU researchers are investigating the effects of broad-spectrum neonicotinoids, such as dinotefuran, on native bees. The work is in progress, according to Ramesh Sagili, an OSU honeybee specialist.
