1 The Impact of ROW Management on Apiary Populations Gary S. Reuter, University of Minnesotawww.beelab.umn.edu

2 Your breakfast without bees Scientific American April 2009 Value of crops in US that depend on pollination: >$18.9 billion $217 billion worldwide

3 Alfalfa Hay – Bee Pollination – Dairy and Beef

4 Your grocery store without bees

5 Healthy Bees Healthy Food Healthy Lives

6 Honey Bees

7 Decline in U.S. honey bee colonies Since 2007, 30-40% of all honey bee colonies die annually Beekeepers struggle to replace losses

9 Wild Bee Pollinators Also in Decline Bumblebee Sweat bee Miner bee Leafcutter bee Orchard Mason bee

10 Photo: Matthew Shepherd Ground-nesting (~70%) Wild Bee Nests Tunnel-nesting (~30%)

11 Wild Bees: Larva feeds on pollen ball provisioned by mother bee

13 750,000 acres of almonds in Central CA requires 1.5 million colonies of honey bees for pollination No Bees, No Nuts

14 72,000 acres of blueberries across U.S. requires 150,000 colonies of honey bees for pollination No Bees, No Berries

15 Colonies trucked in and out because after bloom there are no flowers and many pesticide applications

16 Protect Bees Food If there are flowers blooming, there will be bees foraging

17 What bees eat Pollen - protein Nectar – carbs Water Pollination Happens

18 “Bee” Flowers Major Honey Plants Clover Alfalfa Basswood Buckwheat Wildflowers/ weeds Mustards Vetch Dandelion Goldenrod Sumac Trees - pollen Maple Willow Oak Gardens/ fruit trees Vine crops Berries Can ola Apple

19 Bees collect corn pollen but only when hungry (low protein content) Bees may collect nectar from soybeans in MN only when hot and humid

20 Bees forage 2.5 miles from colony, on average

21 What can the public do? Plant flowers! nator-conservation/ Pay attention to neonicotinoid systemic insecticide use, especially in urban landscapes! Plant bee gardens Encourage roadside plantings of flowers CRP land: put legumes in mix
