Descriptions and articles about the Africanized Honey Bee, scientifically known as Africanized honeybees are more solitary in their foraging than European bees .. The parasitic relationship between A. mellifera scutellata and A. mellifera. Africanized honey bees (Apis mellifera) arrived in the western hemisphere in the s The arrival of these bees and their potentially replacing European Many people identify with the honey bee due to its close relation-. this study was to evaluate the defensive behavior of Africanized bees in Dourados MS, using a . the newcomers' bees in relation to the bees of European origin.
The story of how these bees got to North America and into the United States is the stuff of legend, too. However, the truth about Africanized bees is, as with most myths, not quite so sinister as you may have been led to believe. Yes, they do pose a potential threat and they tend to be more aggressive than other bees, but are they really the threat that some would have you believe? Western Exterminator specialists know the difference between honey bees and Africanized bees and how to handle their nests.

The story of how Africanized bees entered the United States has become legendary. This type bee came into existence when they were interbred between the standard European honey bee and bees from Africa by a man named Warwick E.
He initially bred these bees in Brazil while trying to create a species of bee that would be hardier and adapt to tropical conditions found in South America. He wanted them to be great producers of honey for that region. Kerr kept these bees in a special apiary, away from the other breeds of bees.
Kerr soon noticed that his newly created bees were more aggressive than other bees. They also were more willing to defend a wider radius around their hive than the European bees. He had even more reason to restrict their ability to leave their hives. Inhowever, Kerr had a visit from another beekeeper who noticed that workers in these new hives were having trouble maneuvering around the excluders. He removed them and set them aside.

Doing this accidentally released 26 swarms of the new bees. They very quickly interbred with native bee populations and began spreading across South America and were soon headed north. Africanized bees appear to be limited from expanding to more northerly areas because of cold winters, but in general survive better in the wild than temperate honeybees. These characteristics also make Africanized a potentially serious threat to native and managed pollinator communities in terms of competition for food sources and nest sites.
According to a study conducted in Mexicothe pollination of agricultural crops there has not been seriously affected by the arrival of Africanized bees. However, there have been considerable effects on beekeepers including reduced honey yields because the bees produce less honey than European beesfewer colonies due to abscondingand higher worker wages aggressive bees are harder to deal with.
What should you do if you are attacked by Africanized honeybees?
Run away in a straight line and through trees or foliage if possible the bees will have a harder time chasing you. Find shelter that bees cannot get into a car or house for example.
Stay in the sheltered area even if a few bees come inside with you; Africanized bees like European bees will die after stinging once, and it is better to deal with a few bees than a whole swarm. Do not allow yourself to become trapped in any area you can't get out of: Do not jump into water: Remove the stings as quickly as possible, because they continue to release venom after you are stung.

Wash areas where you have been stung and apply ice if swollen. If you have difficulty breathing, are allergic to bee stings, or have been stung more than a few times contact a doctor as soon as possible. If you met an Africanized honeybee on a flower far away from its nest, would it be more dangerous than a normal honeybee?
Africanized bees are aggressive only if they are being threatened, or if an intruder comes too close to their nest. Aside from humans, what animals are bee predators? The study was also interested in the role different colony social environments and different genetic variation might play in the fitness discrepancies between the two sub-species. African bees were also more likely to store pollen while European bees stored honey.
The study found that worker food preferences determined whether the colony maintained a certain reproductive rate. Worker food preferences have been connected to genotypic variation  at specific quantitative trait loci. The balancing of evolutionary costs and benefits have shaped the distribution of these genotypic traits. A bee population must strike a balance in the distribution of resources towards the growth of the current colony members versus reproduction.
If too much energy is expended on the maintenance of an adult colony, the bees will lose the chance to expand through reproduction but they will have older workers who specialize in nectar resources for energy honey.
If too much energy is spent on reproduction, such a colony will be less equipped to survive drastic seasonal changes because they have younger workers who specialize in pollen for feeding the brood, not energy storage. European bees must survive the winter, an annual event with predictable mortality outcomes.
Trying to meet the energetic needs of the colony and reproduction might decrease their overall survival during the winter and it is more evolutionarily favorable for them to store nectar and honey. Parasitization[ edit ] A strain of Apis mellifera capensis Cape honey bee has monopolized social parasitism of Apis mellifera scutellata hosts in the southern region of South Africa.
Specifically, a strain of A. Social parasitism in the social insects can involve various forms of exploitation that disrupt the normal division of labor in the colony. Ten years later, a single clonal…worker lineage  was found to be devastating A. The resulting breakdown of the division of labor leads to desertion or death of the parasitized colony.
