10 More Bees (like the ‘good old days’) Figures out of South America suggest 100-200 feral colonies per square mile in areas where AHB occur UF/IFAS

11 Why African bees are so successful: Nest usurpation and queen take-over Drone abundance Dominance of African alleles African bee swarming tendencies and reproductive superiority Pest resistance Photo: G.W. Hayes Photo: www.sxc.hu Photo: M. K. O’Malley Photo: HBREL

14 Differences between AHB and EHB Hive Defense and Stinging AHB responds quicker and in larger numbers when colony is threatened. AHB remains agitated longer than EHB Disturbing an AHB colony can result in 6-10 times more stings than EHB Feral nests located near people are more dangerous if not removed Improper removal is dangerous for neighbors and bystanders

15 EHBs Show Little Defensiveness UF/IFAS

17 Stinger Density UF/IFAS

19 Swarming involves honey bee reproduction at the colony level –About 60% of the bees leave colony with queen to establish new colony –Bees left behind rear new queen and remain a functioning colony AHBs swarm more frequently than the EHBs –EHB colonies swarm 1-2 times/year –AHB colonies can swarm 10+ times/yr AHB swarm is smaller than EHB swarm –Some aren't much larger than a coffee cup. 300 AHB swarms per square mile in Central America Differences between AHB and EHB Excessive Swarming

20 Differences between AHB and EHB Selection of Nesting Site EHBs are discriminating in selecting nest sites. –Large hollow cavities (about 10 gallons in size) –Above ground, clean, and dry voids –protected AHBs nest almost anywhere –Smaller, closer to the ground –Underground –Exposed nests in tree branches or elsewhere Difficult to detect AHB in varied nesting locations until too late

21 Q: Where do they nest?

22 A: Everywhere! Photo: J.D. Ellis Photo: W. H. Kern, Jr.

25 In summary, common nesting sites of AHB include: Abandoned vehicles Empty containers Places & objects with holes Fences Lumber piles Manholes Water meters Utility infrastructures Old tires Trees Garages Outbuildings Sheds Walls Chimneys Playground equipment, etc. Florida Dept. Ag.

26 Effects on Florida Agriculture Industry Beekeepers Everyone else

27 Beekeeper Considerations single hive stands White faced veils Jumbo smokers and copious amounts of smoke! Genetic Selection Education Photo: M. K. O’Malley Photo: UF / IFAS Photo: HBREL

28 Frequent requeening with marked queens from non-Africanized areas Negative impacts on beekeeping Loss of apiary locations Lower profit margin LIABILITY (from having and removing bees) Fewer hobbyists Loss of pollination contracts Resource competition (less honey) Photo: M. K. O’Malley Photo: www.sxc.hu Photo: M. K. O’Malley Photo: www.sxc.hu

29 Other Agriculture Considerations: Livestock Photo: www.sxc.hu

30 Pollination (and therefore food!) Photo: www.sxc.hu

31 Food Prices?!?!

32 At-Risk Groups Animals at risk –Tethered or restrained animals. –Penned, caged, or corralled. –Horses and bees don’t mix. Photo: www.sxc.hu

33 Tractor operators and other farm workers must remain alert Photo: www.sxc.hu

34 The elderly and youth tend to be most affected by AHB: In both instances, education is the key to preventing dangerous situations.

35 Precautions for the public Use caution as for snakes/ants Never approach hive equipment Never disturb a swarm Tractor operators take care Be aware of buzzing insect activity at all locations Examine suspect areas before entering or disturbing Be alert in all outdoor situations (hunting, hiking, working, picnicking, etc.) Teach respect and caution of bees Photo: www.sxc.hu Photo: M. K. O’Malley Photo: W. H. Kern, Jr. Photo: www.sxc.hu Photo: Insect IQ Photo: www.sxc.hu Photo: Sean McCann

36 ‘Bee-proofing’ your schools, public facilities, homes, tourist sites, etc. Remove all potential nesting sites (garbage, tires, and other debris) From March-July (swarming season), inspect property weekly for the presence of unusual bee activity Inspect outside walls and eves of your structures Seal openings greater than 1/8-inch in walls, around chimneys, plumbing, and other openings by installing screens (1/8-inch hardware cloth) over such openings (rain spouts, vents, cavities of trees and fence posts, water meter/utility boxes, etc.)

37 During a stinging emergency: Do not stay in place and swat at bees (this always leads to more stings) Do not hide in water or thick underbrush (it may take bees 30+ minutes to calm down or leave an area – remember their colony is likely close) Do not attempt to remove swarm yourself Seek shelter (building, vehicle, etc.) Call 911 Do not attempt a rescue

38 And above all else… RUN
