Beekeeping Glossary
Essential beekeeping terms — from frames to foragers.
ABDOMEN
The third and rearmost section of a bee's body, following the head and thorax. In worker bees, the abdomen houses the stinger, venom gland, and wax-producing glands. In queens, it contains the reproductive organs. You can watch the abdomen pulse rhythmically as bees breathe — a subtle, fascinating reminder of how alive your colony truly is.
ABSCONDING
When an entire colony abandons its hive rather than just sending out a portion as a swarm. Unlike swarming, nothing is left behind — no queen, no bees, no future. Absconding is usually triggered by serious stress: relentless pest pressure, a compromised food supply, or repeated disturbance. Finding an empty hive is disheartening, but understanding why it happened helps prevent it next time.
ACARINE DISEASE
A parasitic condition caused by the mite Acarapis woodi, which colonizes the breathing tubes of adult honey bees. Heavily infested bees struggle to fly and may crawl outside the hive in clusters. Once a major threat, acarine disease is now far less common in the US than varroa, though it still appears occasionally and is worth knowing how to identify.
AFRICANIZED HONEY BEE
A hybrid bee resulting from the interbreeding of African Apis mellifera scutellata bees, introduced to Brazil in 1956, with European honey bee populations. Commonly called killer bees, they are far more defensive than European races, respond to disturbance in larger numbers, pursue threats for greater distances, and have spread throughout much of the southern United States.
AFTERSWARM
A secondary swarm that departs a hive after the primary swarm has already left, typically led by a virgin queen. Afterswarms are smaller and can leave a colony dangerously depleted. In a productive season, a strong hive might throw multiple afterswarms in quick succession. Catching and hiving an afterswarm is rewarding but requires quick action — these smaller clusters establish themselves fast.
ALARM PHEROMONE
A chemical signal released by guard bees and bees that have stung, primarily isoamyl acetate, which alerts the colony to danger and recruits other bees to defend the hive. It has a banana-like scent and is one reason a single sting can trigger a mass defensive response.
AMERICAN FOULBROOD
One of the most serious bacterial diseases in beekeeping, caused by Paenibacillus larvae. It kills developing bee larvae and leaves behind a foul-smelling, ropy brown mass inside capped cells. Spores can survive in equipment for decades. In the US, AFB is a reportable disease in most states, and infected equipment often must be burned. Early detection is essential — know what healthy brood looks like so abnormalities stand out.
APIARY
The physical location where one or more beehives are kept. Your apiary might be a sunny corner of your backyard with two hives, or a dedicated field site with dozens. Good apiary placement considers sun exposure, wind protection, water access, and proximity to forage. The word comes from the Latin 'apis,' meaning bee — so an apiary is quite literally a bee place.
APICULTURE
The practice and science of keeping honey bees for their products and pollination services. Apiculture spans everything from managing a single backyard hive to studying bee biology in a research lab. It blends hands-on craft with genuine science, and most beekeepers find themselves drawn deeper into both the more time they spend with their colonies.
APIS CERANA
The Asian honey bee, a species closely related to the Western honey bee (Apis mellifera) and native to South and Southeast Asia. It is the natural host of Varroa destructor and has evolved behavioral defenses against the mite that Apis mellifera largely lacks.
APIS MELLIFERA
The western honey bee — the species most beekeepers in the US and around the world keep. The name translates from Latin as 'honey-carrying bee.' Apis mellifera encompasses dozens of subspecies, including Italian, Carniolan, Buckfast, and Russian bees, each with distinct temperament, productivity, and overwintering traits. When you open your hive, these are the remarkable insects looking back at you.
APITHERAPY
The use of honey bee products — including honey, beeswax, propolis, royal jelly, and bee venom — for therapeutic or medicinal purposes. While some claims lack rigorous scientific support, bee venom therapy in particular is an area of ongoing research.
