1. Demand for bees drives up rental fees for hives

4. Lock in of bee decline To meet increasing demand, beekeepers continually replace lost and diseased colonies Incentive to do this is high rental fees Bees (and beekeepers) have to work harder This promotes conditions for more bee decline

5. Lock in of bee decline What is the next step in this sequence of events? 1.Demand for luxury crops and potential profit 2.More farmers plant and grow bee-dependent crops in large monocultures 3.Fewer weeds and wildflowers; more pesticides 4.Bees work harder 5.Ongoing declines in honey bees 6.Declining crop yields per acre 7.__________________________

6. Also, as more land is converted, greater reductions in native pollinators and even more enhancement of dependency on honey bees Lock in of bee decline Only honey bees Native bees and honey bees

8. Role of neonicotinoids in bee decline is more complicated

9. Negative impacts of neonics dependent upon mode of dosing Dust release from planting of neonicotinoid seeds is highly toxic Sublethal exposures thru pollen and nectar hard to quantify but can cause mortality Proximity of neonic crops does not mean that bees are feeding on it (dilution effect). Honey bees exposed to many other chemicals Wild bees may be more impacted than honey bees (why?) Role of neonicotinoids is more complicated

10. This is why. Honeybees have larger colony sizes, which can sustain higher losses of foraging bees before showing overall health effects. Yet this suggests another issue. Honey bees are the model organism used in toxicity testing for pesticides. This could explain why some studies have not detected negative effects of neonicotinoids on bees. Worse, this may also mean that native insects may be more greatly impacted.

11. Current large-scale hive losses have historic precedents (Underwood and vanEngelsdorp, 2007)

12. Multiple types of CCD occurring Historic bee die offs occurred before varroa mite and before neonicotinoids In the winter of 2010-2011, the vast majority (>70%) of reported colony losses were not attributed to CCD, as most dead colonies were not missing bee cadavers in the hive or apiary —the hallmark symptom of CCD.

13. Status of the queen, forage availability, varroa mite are bigger challenge to beekeepers than CCD Day-to-day factors more important

14. A greedy reductionist strategy also obscures: The importance of other animal pollinators besides honey bees

15. 1. Obscures the role of other animal pollinators Three-quarters of global food crops rely on a broad group animal pollinators. Honey bees are important pollinators for only a third of North American crops 4000 native bee species in North America

16. Status of Pollinators in North America Long-term population declines for several wild bee species (notably bumble bees), and some butterflies, bats and hummingbirds Paucity of long-term population data and incomplete knowledge of taxonomy and ecology make definitive assessment of status difficult.

17. Status of bee and flower-visiting wasp species in United Kingdom

18. Need to address wild pollinator decline During past 50 years, animal- pollinator dependent agriculture and number of honey bee hives have increased 300% and 45% respectively These numbers also suggest renewed emphasis of practices that reverse declines in richness and abundance of wild pollinators

19. CCD as opportunity CCD has brought attention to bees and beekeeping Beekeeping skills now being passed on to younger generation

20. CCD has catalyzed awareness and promotion of commodity chains for fair trade and organic honey

21. Monofloral honeys produced by local, artisanal beekeepers sought after and sold at higher prices

22. Forest honeys produced by local beekeepers in rural Veracruz state, Mexico

23. Beekeeping can also be promoted as form of development

24. A response to CCD

25. A three-fold response to CCD 1.Need to address more causally stable factors with broad policies Neonicotinoids Evidence is on the balance negative - they are having a detrimental impact on bees and other insects and animals However, their banning may result in the use of older potentially problematic pesticides for which pests have developed resistance

26. 2.More contingent causes require more contextual approach – no single quick fix possible 3.Address systemic issues arising from economic context – why are we so dependent upon honey bees and how can we lessen this dependence?
