All things in the world are mutually exclusive. In the world of bees, there is such a creature, they live from bees, but also for the bees to eliminate harm, they hurt bees, but also help bees, they are masters of assassination, but do not leave a trace. This is the little black-feathered bee that often wanders in the bee colony, a small black bee that makes beekeepers love and hate. Is the black-feathered bee an enemy or a friend to a bee? Is it necessary for beekeepers to kill them? How the black-feathered bee hurts bees and helps bees. Next, we will understand this "silent assassin" black feather bee through 4 aspects.
1. What is the Black Feather Bee
2. How black-feathered bees harm bees
3. How the black-feathered bee helps the bees
4. How do beekeepers deal with black-feathered bees
bee
Black-feathered wasp: 3–9 mm long, with 2 pairs of wings with transparent membranes of black lines, is a small bee of the order Membranoptera. The black-feathered wasp is an insect that lives by parasitic means, so it is also called a "parasitic bee". In the bee colony can often see the figure of the black feather bee, especially when the bee spleen is exposed, you can often find a small black bee that can fly, running between the nest rooms, this is the black feather parasitic bee.
Bees
The breeding of black-feathered bees is to inject bee eggs into the bee larvae by parasitic means, and survive by sucking the nutrients in the bee larvae until the bees die. The bee larvae parasitized by the black-feathered bee are no different in the early stage, and after the introduction of the adult bee, the phenomenon of malnutrition gradually appears, and the phenomenon of slow movement and inability to control itself occurs in the later stage, and finally dies.
Beekeepers can observe the behavior of bees by examining the bee colony and observing the behavior of the bees, and find the worker bees that have been parasitically dead, or by examining the bee carcasses at the bottom of the hive or at the entrance of the nest. As long as you pull the body of the worker bee, you can find that there is a parasite in the body, which is the damage of the bee by the parasitism of the black-feathered bee.
Although the black-feathered bee will parasitize the eggs in the bee larvae, the black-feathered bee's egg-laying and reproduction ability is not strong, and the damage to the bees is very limited. The harm compared to the nest insect is minimal, and after a nest worm has its spleen, it drills into a tunnel, which can cause the death of dozens of covered bee pupae. Therefore, nest insects are the number one natural enemy of bees, and beekeepers should pay more attention to preventing nest insect problems.
Since the black-feathered bee can parasitize bee eggs in bee larvae, it can also parasitize bee eggs in nest worms. According to expert research, black-feathered bees prefer to parasitize bee eggs in nest worms, perhaps because nest worms have richer nutritional value, or bee larvae are guarded by worker bees, while nest worms do not have any protection, and it is easier to inject bee eggs into the body. In short, the parasitic behavior of the black-feathered bee can inhibit the growth of some nest insects and kill some nest insects, which is equivalent to helping the bees eliminate some natural enemies and protect the bee colony from greater damage.
Beekeepers check bee colonies
The black feather bee is both an enemy and a friend, after weighing the pros and cons, we can be sure that a small number of black feather bees have no great impact on the bee colony, and during the period of nest insect harm, it is beneficial to the bee colony. Especially in wild bee colonies, where there is no artificial prevention and treatment of nest insect hazards, the black-feathered bee can act as a nest insect control organism. However, in the artificial breeding of bees, the role of black feather bees is not large, because the effect of artificial control of nest insect harm is better, after all, black feather bees will also hurt bees, so beekeepers have found black feather bees, can kill and kill, there is no need to deliberately keep it.
Now can the beekeepers understand whether the little parasitic bee of the black feather bee is an enemy or a friend? In fact, There is no correct definition of Minnan Bee Brother. If the beekeepers find that there are too many black-feathered bees in the bee colony, they will kill one, as long as they press it quickly, they can kill one. If only three or two black-feathered bees are found in the swarm, there is no need to hunt them down, so let them fend for themselves!
