Hot darn, Slap knows somebody dat used to give presentations on da Africanized Honey Bee...

...Well, in da beginning, there was no intention in creating such a hostile bee at all...As a matter of fact, da whole idea was to creat a honey bee dat could polinate faster and produce more honey at a rapid rate. This was going on in da early 60's in Brazil when a few of the experimental bees escaped into the surrounding countryside, hooked up with the native bees, and became the AHB, (if slap's memory serves him correctly). And, it turns out dat they don't polinate quicker nor do they produce more honey than the more docile European Honey Bee. They are more aggressive, will swarm up to 6 times a year, and build hives nearly anywhere, but prefer ground area. The AHB don't kill or destroy other hives, they actually join that hive, and colonize that hive into the AHB. All the docile bees in that hive they infiltrate become AHB's. Then da queen takes off, and half of the hive joins her, leaving the other half for a new queen. When something gets close to da hive, the docile EHB will send out scouts, about 10 or so, determine if it is a threat, then go back to da hive. The AHB will send thousands to investigate, and then determines that you are a threat, and will send nearly the entire colony at you, and it can be in the tens of thousands if it is a big colony. Dark clothing is what attracts them also, they be thinking you are a bear and are going to steal their honey. Also, while swarming, they will not attack, they are looking for a place to stop and possibly build a hive, but won't attack in this state. Question is, are the AHB's becoming more docile the more they swarm into areas and colonize with the European Honey Bees. Doesn't look like it. BUT, all known AHB colonies are destroyed when discovered. There really doesn't need to be any more study on them, dats been done.
Hope the info helps...If you are engaged in an AHB attack, RUN YO ASS OFF.
As for destroying them, the bee folks have done perty good in controlling them when they are found, and will be moved or destroyed. But to destroy all bees, dat wouldn't be good at all, we be needing them Honey Bees, they is very important.
