American killer bees – a hybrid resulting from crosses of African and honey bees. Characteristic feature the behavior of these insects is that at any potential they attack the offender with the whole swarm at once, without leaving no chance of salvation.
Once African bees attracted beekeepers such positive qualities like honey collection productivity and hard work. However, an attempt to cultivate such working insects has become fatal for professionals from Brazil. In the middle of the past centuries, fulfilling the request of beekeepers, geneticist Warwick Kerr brought bees from africa. Crossbreeding experiments began during of which several families of hybrid bees broke free and have bred. Now they live in many American countries, in particularly in the USA.
Killer bees, unlike their other relatives, protect their beehive even if the “enemy” is far superior to them in strength and capabilities. When a threat occurs, the guard bee selects a special pheromone from the sting – and it signals an alarm the whole bee swarm. This pheromone killer bees emit much more than European relatives, and therefore to protect their “native At home, three times as many insects rise.
Moreover, when one bee stings the victim, then, except for the poison (where stronger than the poison of a European bee), it also injects pheromone, leading the whole swarm into a full fury. Chase your A killer bee can kill half a kilometer or more. Save in the water from impossible: insects will wait until the victim get out on land, and then continue the attack.
It is difficult to imagine what will turn out for the population of America proximity to such creatures, as their behavior is often unpredictably. All attempts to fight the little killers so far were unsuccessful, although this struggle is no longer ongoing year.
