Why bees throwing larvae out the front of the hive!

 

First, let's look at why bees throw brood out of the hive. One of the mechanisms of the fight against diseases of bees is the hygienic behavior of bees - understanding in which cells the dead larvae are located, they open them and the bees throw out the brood from the hive. Thus, bees can both eliminate the disease and spread it. So the bees throw away brood that died from varroatosis and other diseases, as well as from other causes not related to diseases, for example, brood died from extreme heat or other causes.
Another reason why bees throw brood out of the hive is bee cannibalism, when the bees do not have enough protein food and they are forced to eat the brood.
However, there are a number of reasons why bees throw brood out of the hive, which we will discuss below.

Why are my bees dragging out brood out of the hive in the spring?

Why do bees throw out brood in spring? Consider the most common situations.

• One of the most common reasons why bees throw out their brood in spring is that the nest of bees is not insulated and the brood has become supercooled during cold weather, the so-called chilled brood. A chilled brood of bees also occurs in case of too rapid expansion of the nest, therefore it is necessary to expand the nests carefully, especially in the case of the Ruta hive, where expansion occurs immediately by the body and chilled brood of bees is very common. To understand what it is chilled brood, you need to look - the shape of the pupae should remain the same, but their color changes: it will range from brown to black.
• Almost immediately after the exhibition of bees, the beekeeper may find that the bees threw out the brood, this may well be the result of winter brood, when the bees could not heat it and it froze, and the bees were able to throw it out only after the exhibition of the hive from the premises. So this case, when the bees throw out the brood, can be attributed to the chilled brood of the bees.
• No less common situation, why the bees throw out the brood in the spring is the lack of food, including protein food. Oddly enough, but many beginner beekeepers leave food in the hive to a minimum, so the bees initially begin to feed a lot of brood, but then, in order to grow part of the brood, they begin to eat eggs and pupae, throwing the brood out of the hive, in this case, the pupae are, as it were, sucked out .
• No less common situation, why the bees throw out the brood in the spring is the varroa mite. If in the fall there was a large tick infestation in the family, then in the spring, while there is little brood in the family, the tick crowds into the brood cells in large quantities, killing the brood. As a rule, in this case, the brood thrown out of the hive is underdeveloped, they may lack wings and legs, often a tick is visible on such pupae.
• An equally common situation, why bees throw out brood in the spring, is ascospherosis. The causes of this disease, signs and treatment are described in detail in the material how to treat ascospherosis.

Thus, in order not to observe the discarded brood near the hive and not to puzzle over why the bees discard the brood, the beekeeper needs to treat the bees from the tick in the fall, after the first flyby of the bees, clean the bottom, and at the first opportunity replenish the stocks of food in the hive, both carbohydrate and protein - give the bees protein candy or honey protein paste, insulate the nest and do not forget to put a drinker in the apiary for the first flight or provide the bees with intra-hive drinkers. Water in the spring is extremely important for the bees. It is correct to expand the nest in the spring.

If the beekeeper still finds the brood thrown out by the bees near the hive, he needs to examine the dead brood and determine the cause of his death and take action.

Why are bees dragging out pupa out of the hive in the summer?

Why do bees throw out brood in summer? There are no less reasons why bees throw out brood in summer than in spring. For what reasons is this happening.

• Intense heat in the nest destroys the brood, so the beekeeper must help the bees fight the overheating of the bee nest in the heat.
• Drought and abnormal heat and dry winds interrupt the honey flow, due to which the bees may begin to starve, so near the hive you can see how the bees throw out the brood from the hive, in this case the pupae are as if sucked out. In this case, the color of the discarded brood remains white, the pupae also have a healthy white color. In this case, the beekeeper must create the appearance of a bribe by feeding, otherwise the colony will be greatly weakened, will work poorly at collecting honey and die in winter.
• In summer it is possible that the bees throw away their brood when they have no water, this may well happen when migrating beekeeping to a new place, so the beekeeper needs to take care of the source of water for the bees.
• Diseases of bees do not leave the apiaries, and in the summer, viral diseases of bees can be observed in apiaries. For example, with sac brood, near the hive, you can observe how the bees throw out the brood of drones, often gnawed into pieces, this is a sure sign of this disease (the fact that the bees throw out the brood of worker bees is not so noticeable). In this case, it will not be superfluous to check the discarded brood and colony for diseases. And the more accurately the disease is diagnosed and the earlier treatment is started, the more likely it is to save the bee colony. Beekeepers should remember that in modern conditions in apiaries, mixed invasions have become commonplace, situations when two or more diseases are present in a bee colony at the same time, which makes it difficult to diagnose and treat bees.
• Also, do not forget that the drone brood thrown out by the bees from the hive may indicate the termination of honey collection, but in this case the drone brood will be normally developed.
• Brood thrown out of the hive by bees can also indicate other viral diseases, such as acute paralysis of bees. Foulbrood - European foulbrood, American foulbrood, Parafoul.
• Why do bees throw out their brood while collecting honey? It is believed that during a good collection of honey, bees can throw out the brood in order to free up cells for honey. However, most likely, this judgment will not correspond to the truth, the beekeeper needs to carefully look at the brood thrown out by the bees. In most cases, the beekeeper can find that the discarded brood is underdeveloped and infested with a mite, and this only indicates that there was an outbreak of mite development in the spring, in autumn and winter such a colony will die if urgent measures are not taken.
• Another reason why the bees throw out the brood is poor-quality foundation, in this case the brood dies due to the presence of chemical compounds in it and the bees throw the brood out of the hive. But fortunately this doesn't happen often.

Why are my bees dragging out brood out of the hive in the autumn?

Why do bees dragging brood out of the hive in autumn?
Bees throw brood out of the hive in autumn in most cases for the same reasons as in spring, but there are some nuances.

• chilled brood, namely, in autumn there may be sudden cold snaps, causing the death of the brood.
• An important reason why bees throw brood out of the hive in autumn is the mite, just like in the spring, the number of brood may decrease and the number of mites increase. So the fight against varroatosis in the apiary should be carried out constantly, throughout the season.
• Wax moth could start in a weak bee colony and then in autumn the bees throw out the brood from the wax moth damaged cells, but this case is easy to notice.
• Why bees throw drone brood out of the hive in autumn is quite clear, if there is a mated queen in the bee colony, then drones and their brood are no longer needed, but in this case the brood thrown out of the hive will be normally developed.

Thus, the beekeeper taking a number of measures, such as combating mites, providing bees with food, keeping the hive warm in spring, and controlling diseases, can significantly reduce the number of reasons why bees throw brood out of the hive and prevent colonies from weakening.
