The
behavior- not the appearance - of the Africanized Honey
Bee is different from the European Honey Bee in four
major ways
The Africanized Honey Bee (AHB) swarms
much more frequently than other honey bees. A colony is
a group of bees with comb and brood. The colony may
either be managed (white hive boxes maintained by
professional beekeepers) or wild (feral).
A group of bees that are in the
process of leaving their parent colony and starting a
nest in a new location is called a "swarm." Usually a
new queen is reared to stay with the parent colony and
the old queen flies off with the swarm. Scout bees often
locate potential nest sites prior to swarming, but the
swarm may spend a day or two clustered in impressive,
hanging clumps on branches or in other temporary
locations until the bees settle on a new nesting site.
If they can't find a suitable location, the bees may fly
several miles and cluster again.
Typically a European Honey Bee
(EHB) hive will swarm once every 12 months. However, the
AHB may swarm as often as every six weeks and can
produce a couple of separate swarms each time. This is
important for you to know, because if the AHB swarms
more often, the likelihood of your encountering an AHB
swarm increases significantly.
Regardless of myths to the
contrary, Africanized Honey Bees do not fly out in angry
swarms to randomly attack unlucky victims. However, the
AHB can become highly defensive in order to protect
their hive, or home. Again, it is now better to
consistently exercise caution with respect to all bee
activity. So keep your distance from any swarm of bees.
The AHB is far less selective
about what it calls home. The AHB will occupy a much
smaller space than the EHB. Known AHB nesting locations
include water meter boxes, metal utility poles, cement
blocks, junk piles, and house eaves. Other potential
nesting sites include overturned flower pots, old tires,
mobile home skirts, and abandoned structures. Holes in
the ground and tree limbs, mail boxes, even an empty
soda pop, can could be viewed as "home" to the AHB.
The Africanized Honey Bee is
extremely protective of their hive and brood. The AHB's
definition of their "home turf" is also much larger than
the European Honey Bee. So, try to allow ample physical
distance between the hive. At least 100 feet, or the
width of a four-lane highway, is a good distance. The
best advice is that if you see a bee hive, start moving
away immediately.
In 2005,
Africanized Honey Bees showed up for the first time
in Louisiana, Arkansas, and Florida. The arrival in
Florida was not contiguous with the bees' spread
from the Southwest. It was most likely a result of
human assisted transport, by which trucks, ships,
railroad cars, or other types of transportation
inadvertently bring Africanized Honey Bees into new
areas.
Usually,
human−assisted transport finds are not considered
part of Africanized Honey Bees' spread. But because
they have been found in 14 counties, the State of
Florida now considers Africanized Honey Bees to be
established there.
Among
Agricultural Research Service's recent research
accomplishments related to the bees is new guidance
for beekeepers on the best time to re-queen hives to
reverse Africanization of Honey Bee colonies. Queens
of known genetics, from reputable breeders, should
be introduced into hives in the fall to give them
the best chance of being accepted by the bee
colony.
