To roll out this important research paper, Dr. Marla Spivak, an entomologist and Distinguished McKnight University Professor at the University of Minnesota, spoke at three events in Washington, D.C.: (1) a morning session with the National Council of Farmer Cooperatives, (2) an NC-FAR lunch seminar with staffers from the House of Representatives, and (3) an NC-FAR afternoon seminar with staffers from the Senate.
Full commentary available here--includes a link to Dr. Spivak's presentation.

“Our greatest
challenge going forward is how we protect our pollinators . . . and control our
crop pests at the same time,” Spivak said, stressing that it is not an “either-or”
proposition. Instead, a “rebalancing” needs to take place so bees can be
protected next to corn and soybean fields, but also in apple orchards and
almond groves.
“We are in
the middle of this glorious pollinator revival, and people, because they’re
paying attention to bees and monarch butterflies, they’re starting to realize
they can help,” she said.
Spivak said
about a third of the human diet, "if you eat lots of fruits and vegetables
(as you should), is dependent on bee pollination." And the CAST commentary
said that "pollination services contribute directly to the economy and
food security," citing annual revenues of $11.7 billion from the sale of
honey bee-pollinated fruit, vegetable, and nut crops in the United States.
"The additional
value of pollination services by the thousands of species of native bees that
live in the wild throughout the (U.S.) is estimated at $3.4 billion annually,
and the total economic value of pollination worldwide, by all bees, was
estimated at $216 billion."
The Importance of Honey Bees (from the press release)The authors of this commentary examine the state of honey bee health, including recent declines in population. They also explain why the public should be concerned. Honey bee pollination "contributes directly to the economy and food security. Human nutrition depends heavily on honey bees."
This science-based paper looks at the stressors threatening colony health. The task force authors then offer concrete ways that bees could be protected:
• Integrated pest management approaches
• Best management practices such as curtailing
pesticide drift and preventing off-label use
• Better record keeping and communication about management and practices
• Increased availability of high-quality floral nutrition for bees in urban and ag settings
• Land management activities and policy decisions that are informed through science
Most scientists and beekeepers agree that honey bee health decline is the result of multiple stressors. The authors of this paper believe that solutions will come by increasing pollinator foraging opportunities and enriching the natural habitat. "Careful and appropriate pesticide use, conservation, and sustainable agriculture practices will help ensure the availability of the pollinators needed to secure a stable food supply."
