As a new beekeeper with my first hive I read as much as I can about Bees and try to get experience in other apiaries. With a friend we recently had a “useful” experience in his out apiary with some very naughty bees with my colleague getting many stings in his suit (and one through the suit) as he inspected the most difficult hives, I did not see any stings in my suit, had a couple in the gloves; the bees followed us out for a long time and distance – he is going to re-queen some hives.
After the out apiary visit we gave my nice quiet bees an inspection – all appeared OK, they are a strong colony with two supers getting stores; I plan to split it.
I took my suit off and about 30 minutes later, wearing the same cloths I had been wearing under my bee suit, walking round the garden some distance from the hive I received persistent attention from one or two bees, as a result I tripped and got a black eye! I also found a sting in the back of my sports shirt collar, so this sting had occurred after removing the bee suit; probably during the persistent attention.
I mention these points because I am a beginner, hopefully when I have some years of experience I will gain the skill and sensitivity of more experienced beekeepers but there are a number of new beekeepers; we will all learn by experiences (good and not so good) and maybe these notes are relevant to them.
Good beekeeping appears to be about following defined procedures – drift from the proven path and get stung! So, from the experience above and reading stuff below I offer the following to new beekeepers:
- A honey bee that is away from the hive foraging for nectar or pollen will rarely sting, except when stepped on or roughly handled.
- Honey bees will actively seek out and sting when they perceive the hive to be threatened, often being alerted to this by the release of attack pheromones.
- Bee attack pheromones can, in sufficient quantity, effectively “bathe” a beekeepers suit and to a degree body and clothing under the suit in attack pheromones; and that this signal can last a while, maybe a day or more.
- Make sure your suit and gloves are clean and free from old stings before you visit a hive i.e. no pheromone trail to excite the sting instinct or attract unwelcome attention.
- Make sure you and your clothes under the bee suit are not carrying pheromone from a recent inspection particularly when aggressive behavior was encountered, this applies when conducting an inspection and possibly more importantly after the inspection when outdoors and not wearing the bee suit.
- After visiting a hive, always and particularly when there is some excitement and maybe evidence of stinging; keep the suit on until well clear and you are certain that no bees are following you or getting in your car.
ALARM PHEROMONES are produced by two separate glands. The first originates in the mandibular gland. When guard bees are alarmed by an intruder, they put off this alarm scent that tells the other bees that there might be a problem. This scent is especially prone to be released when the problem is a MOVING intruder. This is why it is important to make slow movements around a beehive so that you don’t alarm the guard bees.
Honeybees generally attack only to defend their colony, but will also attack if they are seriously disturbed outside the nest. Common sources of attack stimulus for honeybees include alarm pheromone, vibrations, carbon dioxide, hair, and dark colors (Crane 1990). This makes sense because mammals, which are common predators of bees, are usually hairy, dark colored, and exhale carbon dioxide. If you think about this you will realize that bees are drawn towards attacking sensitive areas around the head of a common predator.
The second stage of the ALARM pheromone comes from the sting gland. This chemical messenger is released after the stinger has penetrated the skin of the intruder. It is not released until the sting, and is much stronger than the scent given off by the mandibular gland. After the sting takes place, and the stinger (with poison sac and all) is ripped out of the abdomen of the bee, the alarm scent is at its strongest. As a matter of fact, the scent is now all over the surface of the exact spot where the sting took place and functions as a “bulls-eye” for the other guard bees to attack.
Stinging is the ultimate final act of a honeybee because soon after, she will die. First the bee becomes alerted; she takes on a guarding stance and protrudes the sting, which recruits other bees by releasing alarm pheromone. Secondly, the bee will search for the source of stimulus and orient towards it. Finally she will attack; emitting a high pitched buzz and making body thrusts towards the source of disturbance. Once the bee’s sting is inside a victim, it pumps out more venom and emits alarm pheromones. During this time, the stinging bee will spend its dying moments distracting its victim by flying around its head as if it were going to sting again.
