Domestic Honeybees (EHB)
![Page 3: Controlling Africanized Honey Bees Philip G. Koehler Dept. of Entomology & Nematology University of Florida Modified by Anita S. Neal & Ed Skvarch St](https://reader030.vdocument.in/reader030/viewer/2022032523/56649d945503460f94a7b876/html5/thumbnails/3.jpg)
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.
The Honeybee Colony

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

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.

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.
AHB - Behavior/Defensive Response
![Page 10: Controlling Africanized Honey Bees Philip G. Koehler Dept. of Entomology & Nematology University of Florida Modified by Anita S. Neal & Ed Skvarch St](https://reader030.vdocument.in/reader030/viewer/2022032523/56649d945503460f94a7b876/html5/thumbnails/10.jpg)
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
Differences between AHB and EHBSwarming
![Page 11: Controlling Africanized Honey Bees Philip G. Koehler Dept. of Entomology & Nematology University of Florida Modified by Anita S. Neal & Ed Skvarch St](https://reader030.vdocument.in/reader030/viewer/2022032523/56649d945503460f94a7b876/html5/thumbnails/11.jpg)
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

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

Bee Proofing
Africanized honey bees nest in a wide variety of locations Need openings >1/8 inch Cavity behind the opening for a nest
Eliminate shelter Caulk cracks in walls, foundation, and roof Fill or screen holes >1/8-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
Hole leading to cavity

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.

Controlling This should be done only by a registered
Pest Control Operator with a General Household Pest Control License that is wearing protective gear.
![Page 22: Controlling Africanized Honey Bees Philip G. Koehler Dept. of Entomology & Nematology University of Florida Modified by Anita S. Neal & Ed Skvarch St](https://reader030.vdocument.in/reader030/viewer/2022032523/56649d945503460f94a7b876/html5/thumbnails/22.jpg)
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.

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.

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
