Why are africanized honey bees invasive species?
Primarily because they basically took over the jobs of passive Honey Bees that were native to the Americas before the Africanized Species arrived. Africanized bees produce honey at a substantially greater rate than their non-stinging counterparts and so honey farmers are often forced to used the new breed of stinging bees to maintain high productivity. Any species not native to an area that replaces a native specie’s niche in that ecosystem is considered invasive.
