The map lists a county only when that state officially declares it to be Africanized. Explore some bee anatomy and become an expert on spotting honey bees. Africanized honey bees (AHBs) are a distinctive lineage of A. Some bees are social like the honey bee and other bees solitary, like digger bees, and orchid bees. The Africanization of honey bees (Apis mellifera L.) in the Americas is among the most extensive insect invasions in the world, with large-scale effects on the economy and ecology of a whole continent. It is now posted on the Agricultural Research Service's (ARS) website at The map shows the spread of Africanized honey bees (AHB) by county by year.ĪHBs have continued their slow territorial expansion in the southern United States, and have now been confirmed in nine states. There is even an Africanized honey bee that has a reputation for being more aggressive than its European honey bee cousin. The map of Africanized honey bees' spread in the United States has been updated. USDA Map of Africanized Honey Bee Spread Updated Click the image for more information about it. These bees have migrated since their introduction, reaching the lower United States in 1990. Children, the elderly, and handicapped individuals are at the highest risk of an. Africanized honey bees have been known to pursue their victims for more than 500 feet. These African bees mated with the European honey bee to create the hybridized or 'Africanized' honey bee. Africanized honey bees are provoked to attack sources of loud noise and vibrations, as well as large, dark-colored moving objects that occur within 50-150 feet from the colony. Despite color differences between these two bees, mostly they can't be identified by eye. The Africanized honey bee has descended from tropical African bees (Apis mellifera scutellata) that were introduced to South America in 1956.
