Africanized honeybees, also known as 'killer bees', were the unintentional result of an attempt to create a more disease-resistant strain of domestic honeybees by crossbreeding with wild African honeybees. The resulting hybrids inherited the improved disease resistance of the African bees, but also inherited their aggressive swarming behavior. They then proceeding to escape from the breeding experiment and spread in the wild.
Despite their aggressive behavior, they are used in some areas commercially for honey production. You just have to be very, very careful when harvesting the honey.
Being an artificial strain, they wouldn't necessarily exist in DF. An equivalent might be if Goblins had their own breed of Evil bee they used for producing evil honey and defending their (currently non-existent) obsidian towers.
