Title: Controlling Africanized Honey Bees


1
Controlling Africanized Honey Bees
  • Philip G. Koehler
  • Dept. of Entomology Nematology
  • University of Florida
  • Modified by Anita S. Neal Ed Skvarch
  • St. Lucie County Extension

2
Domestic Honeybees (EHB)
3
The Honeybee Colony
  • Apis Races
  • 24 races of Apis mellifera.
  • Different physical and behavioral characteristics
    - body color, wing length, susceptibility to
    disease.
  • Races can mate with each other.

4
Nest
  • Colony may contain 40,000 to 60,000 or more bees
    during the late spring or early summer.

5
Africanized Honey Bee (AHB) History
  • First bred to create a honeybee better suited for
    tropical conditions.
  • 1957 - 26 African queen bees were released or
    escaped from breeding in Sao Paulo, Brazil.

Distribution of AHB in the U.S.

AHB - Behavior/Defensive Response
  • 3-4 times as many bees to respond to the threat.
  • 10 times more stings per encounter than European
    Honeybees.
  • Defend wider area around nest than European
    Honeybees.
  • Can chase victims for ¼ mile.

10
Differences between AHB and EHBSwarming
  • AHB swarms more frequently than the EHB
  • EHB colony swarms every 1-2 yrs
  • AHB colony swarms 4-8 times/yr
  • AHB swarm is smaller than EHB swarm
  • Some aren't much larger than a coffee cup.
  • Swarming reduces the number of bees in a colony,
  • reduces work force
  • diminished honey production
  • Continuous monitoring is required to

    detect small swarms and incipient

    colonies before establishment

11
Differences between AHB and EHB Aggressive Hive
Defense and Stinging
  • AHB responds quicker and in larger numbers when
    colony is threatened.
  • AHB remains agitated longer than EHB
  • Perturbing an AHB colony results in 6-10 times
    more stings than EHB
  • Nests are dangerous if not removed
  • Improper removal is dangerous for neighbors and
    bystanders

12
Differences between AHB and EHB Reproductive
Capacity
  • AHBs have higher brood production and less honey
    storage than EHB
  • AHBs produce more bees in a shorter period than
    EHB
  • Dangerous numbers of AHB bees develop rapidly

At-Risk Groups
  • People likely to interact with bees
  • Outdoor workers
  • Military
  • Sports enthusiasts
  • Rescue personnel
  • People incapable of handling an interaction
  • Children
  • Elderly
  • Handicapped
  • Animals
  • Tethered or restrained animals
  • Penned, caged, or corralled

17
Areas of Higher Risk for Bee Attack
  • Monitor or clear area before entry
  • Schools
  • Recreation and training areas
  • Lawnmowers, chain saws, weedeaters
  • Domestic animals
  • Large motorized equipment
  • Homes

18
Bee Proofing
Hole leading to cavity
  • Africanized honey bees nest in a wide variety of
    locations
  • Need openings gt1/8 inch
  • Cavity behind the opening for a nest
  • Eliminate shelter
  • Caulk cracks in walls, foundation, and roof
  • Fill or screen holes gt1/8-inch in trees,
    structures, or block walls
  • Screen attic vents, irrigation boxes, and water
    meter box holes
  • Remove trash or debris that might shelter honey
    bees
  • Fill or cover animal burrows
  • Tight fitting window screens
  • Close shed doors tightly and keep in good repair

Swarm traps

Swarm trap
Swarm lure
  • Cone style trap is made from recycled wood pulp
  • Lures used to attract bees in swarm traps or hive

20
Swarm Traps
  • Entomologist Justin Schmidt examines an ARS honey
    bee trap used to lure Africanized bee swarms and
    prevent their establishment in walls of
    buildings. Captured swarms are easily removed or
    destroyed with soapy water.

21
Controlling
  • This should be done only by a registered Pest
    Control Operator with a General Household Pest
    Control License that is wearing protective gear.

22
What If You are Stung? - First Aid
  • Bees leave behind a stinger attached to a venom
    sac. Do not try to pull it out, as this may
    release more venom. Gently scrape it out with a
    blunt-edged object, such as a credit card or dull
    knife. Wash the area with soap and water. This
    should be done several times a day until the skin
    is healed.

23
First Aid
  • Apply a cold or ice pack, wrapped in cloth for a
    few minutes. Apply a paste of baking soda and
    water and leave it on for 15 to 20 minutes, or
    dab on a bit of household ammonia. Take
    acetaminophen for pain.

24
First Aid
  • Seek emergency care if you have any of these
    symptoms, because they indicate an allergic
    reaction
  • Large areas of swelling
  • Abnormal breathing
  • Tightness in throat or chest
  • Dizziness
  • Hives
  • Fainting
  • Nausea or vomiting
  • Persistent pain or swelling

25
Summary
  • Be Aware
  • Cover Your Face
  • Do Not Make Aggressive Movements
  • Move Quickly to Safe Areas
  • Contact a Bee Removal Service
  • Prevent / Remove Potential Nesting Sites
