What s the reason why bee larvae come out of the house more slowly?

"White-headed pupae": It is a bee pupa that is bitten by worker bees after death, revealing a pale head, so people vividly call it "white-headed pupae". Beekeepers have different opinions on the "white-headed pupae", diagnosis and **, some beekeepers think that there is a white-headed pupa exists, there must be a nest insect harm, so they concentrate on the nest worm, but the "white-headed pupae" still continue to appear, and some even wipe out the whole field.

Cystic disease: 1 pathogen. Medium bee rearing. Artificial breeding.

Disease and enemy control. The causative agent of cystic larval disease in honeybees is the cystic larval virus, which mainly infects larvae and causes disease and death. Generally, it invades at the 1 2-day-old small larval stage, and has obvious symptoms at the 5 to 6-day-old large larval stage, and can also reproduce in adult bees, but does not show symptoms.

The cystic larval disease virus is not strong in the external environment, it can only survive for 10 minutes in 59 hot water, 3 weeks in room temperature and dryness, 1 month in the carcass of the disease, and only 7 10 days if the carcass of the diseased insect decays. It can survive for 100 to 120 days in bee food, and the virus remaining on the wall of the nest can survive for 80 to 90 days in summer and 90 to 100 days in winter. Direct sunlight for 4-7 hours can kill.

2. Most of the larvae died within 6 days, 30% died before capping, and 70% died after capping. In the early stage of the disease, "flower seeds" appear, and then "pointed heads" appear on the spleen surface, and the larvae's head leaves the nest wall to form a hook-like larvae, and the body color changes from pearl white to yellow, and then to brown and black-brown. After extraction, the worm body presents a typical sac-like pouch.

When the lid of the diseased insect house sinks, the worker bee bites a small hole in the cover or opens it and drags it out of the nest; The body color of the dead larvae that have not been dragged out changes from light brown to dark brown or black, and later appears as a dry piece, like a dragon boat. The body of the dead insect does not warp after drying, is odorless, non-sticky, and easy to remove.

The kitchen is relatively slow, probably because he is not particularly well developed when he is developing, and he cannot fly out independently, or it may be because there is crowding when there are too many bee colonies.

The bees are slower to come out of the house again, this may be a problem that the weather is too hot, it doesn't matter, wait slowly.

Feed more food, you feed the bees more food, the bees are full, and then they will feed those larvae, feed, and raise faster.

This is due to the lack of energy in his body for his strength.

Because he still needs to grow, if he leaves the house too quickly, it will be life-threatening.

Bee larvae are slower to come out of the house, possibly due to the weather. But it's also a process.

First: nest bugs.

For traditional barrel beekeeping, the bee tribe believes that the most likely situation of bee larvae falling from the nest is still nest insects, because of traditional barrel beekeeping, the general beekeeper does not take honey excessively, and because of the difficulty of traditional beekeeping and bee separation, most of them still belong to the semi-wild mode of breeding, and there will be no excessive bee distribution, but because the bee spleen cannot be replaced for a long time, the nest insect is the biggest harm to barrel beekeeping. So how should we prevent and ** nest insects in traditional barrel beekeeping?

In the view of the bee tribe, the traditional barrel beekeeping is prone to two extremes, that is, excessive honey extraction and no honey, in fact, these two methods are wrong, relatively speaking, excessive honey extraction will not cause the flood of nest insects, so if the use of traditional beekeeping has a flood of nest insects, long-term non-honey is more likely to appear.

Because the traditional barrel beekeeping bee spleen is fixed, so the best way to replace the bee spleen is to use the way of diligent honey, here is not to say that we see honey to take, for the prevention of nest insects, even if we take honey thoroughly once a year can achieve the effect of prevention, so we still have to wait for the honey to be covered, and then use the partial honey method.

The method is to first remove the honey in the upper part of the bee bucket or the honey on one side, and then turn the bee bucket upside down, because the bee honey storage has an upward nature, soon the bee will build a nest and lay eggs in the place where the honey is removed for the first time, and the original position of the larvae out of the room becomes a honey storage area, and so on until the original position of the honey is covered, we take off the honey on it, so that the nest spleen in the entire bee bucket is all replaced. Due to the irregular spleen of the honeycomb taken from the wooden barrel, we can make corresponding honey extraction tools according to the specific situation when taking honey.

If we find that the nest worms are already infested and harming the entire colony, the best thing to do is to remove all the spleens from the entire bucket and let the bees rebuild their spleens. This method of excessive spleen cutting has a certain danger, if the operation is not careful, it is easy to cause bees to escape from the colony, so we should keep bees in the breeding process every year step by step to extract honey, cut off the old nest spleen in the bee bucket.

This is a copy of the bee

Clean-up behavior, generally 3 days after the introduction of the worker bees began to feed the larvae bees, 7 days after the secretion of royal jelly, 16 days after the home to collect honey.

The decision is made by the chemicals of the dead pupae to make it do this, and it can make the queen bee lay eggs again, in order to speed up the reproduction, is this the case with your bees? This disease will be contagious, this is a dead pupal disease to buy from the bee connoisseur or the bee pharmacy can also go to the ** online to buy Pupal Taikang spray on the bee page, I still hope you don't want those pages, otherwise your bees will not survive the winter, less than half a month out of the new house is almost 0, change the page don't think it is harmful to them and change the box, because there is a virus, don't worry, the situation is indeed very serious, you have to buy Pupae Taikang spray Oh, it will be good,

The full name is bee cystic larval disease, also known as "rotten seed disease", which is a malignant viral infectious disease, which is common in Chinese bees and is extremely destructive. According to folklore, the virus can survive for up to 15 years. In other words, once the disease occurs, beekeeping in this area will not be able to be maintained for 15 years.

Cystic larva disease is caused by the larval virus, which multiplies in adult bees. Through the feeding activities of worker bees, they enter the larvae with food, and generally occur seriously in spring and autumn.

With penicillin, viral. There is also a mother-eater. of these.

Feed once every two days. Depending on the severity of the colony, if it is very severe, shake off all the spleens and rebuild them, and then feed them several times. Until you know that larval disease does not appear

You're a larval disease. You try these medicines first. If it doesn't work, you shake off your spleen and have to make a new spleen.

Remember to cut off the queen bee wings when shaking your spleen. Otherwise, you may escape. Continuous feeding for months.

Maybe the colony will slowly get better. Recover on your own.

There is no suitable environment nearby, such as not enough flowers for them to collect.

The other is that there may be some pesticide residue or chemicals nearby, which can be fatal to them.

But there is one more point, but the odds are relatively small and the most terrifying. You don't have a queen bee.

There are many types of bees, and there are also various channels for laying eggs, such as leaf-cutting bees, which can cut rose leaves and use leaf pads to make their own nests in rotten wood, and sand wasps, which dig nests in the sand, bicolor wall bees can build nests in snail shells, and so on. The one you mentioned is a parasitic wasp, some of which lay their eggs in the caterpillar's body, and the larvae feed on the nutrients in the caterpillar's body. There are also various types of parasitic wasps, in short, different parasitic wasps lay eggs in different hosts, but they all need to inject toxins to paralyze the host.

Is it a newborn bee?

Larval diseases are roughly European larval putrid disease, weekly larval putrid disease, cystic larval disease, etc., of which the former two are common, the latter is generally the center of the disease, the first two are generally accompanied by rancid odor, the typical symptom is the appearance of flower arrangement pupa spleen, the main identification method of larval disease in Europe and the United States is that the European disease is generally the larval death within a week, and the American disease is the larval death of the adult pupation. But the larvae of both diseases do not crawl out of the nest, and the landlord says that the larvae are usually starved.

Larval disease in Europe and America is mainly an infectious larval disease caused by a combination of bacteria such as Streptococcus beehibi, Bacillus beelets, Streptococcus meless and Bacillus bee. **Generally antibiotics. The traditional method is:

Add 100,000 200,000 units of streptomycin or oxytetracycline per kilogram of syrup, feed 50 100 grams per frame bee, and administer once every 4-5 days, 3 or 4 times for a course of treatment.

This disease is extremely ferocious and not easy**I hope the landlord takes it seriously.

White bugs are susceptible bee larvae that have been thrown out by worker bees.

Larval death is infection with chalk.

Regularity and symptoms generally occur in spring and early summer, the outside temperature is 19 30, and the air is humid. Fungal infectious disease of large larvae of bees caused by parasitism of Hycoccus bees. Grayish-white or black flaky hard larvae may be found at the door of the nest.

The lid of the diseased nest is uneven, with depressions and perforations. Dead larvae are dry, white or grayish-black, odorless, non-sticky, and easily removed.

Prevention and treatment of this disease is not easy after the onset of the disease**. When bees are breeding in spring, do not feed bee pollen from unknown sources, and replace the camellia pollen spleen or camellia pollen into the box to reduce the occurrence of chalk. When the onset is mild, drugs can be used**, calcium propionate is added to the syrup to feed the bees, and each group is fed with kilograms of syrup (containing grams of calcium propionate).

In severe cases, the spleen should be replaced, and more bees than spleens must be fed with syrup.

The best method of bee larval disease: Many beekeepers pin their larval disease on drugs, but in fact it is difficult to completely **. In practice, measures such as spleen replacement, king replacement, and box replacement are used to destroy all nest spleens and insect spleens in the disease group, and then cooperate with medication.

First of all, move the sick group to a place 3 kilometers away to isolate**, place the disinfection beehive in the position of the sick group, put a few empty spleens in the box, shake the sick bees into the beehive, make more bees than spleen, kill the queen bee of the swarm, and induce a new queen bee. It is not a pity to destroy all the nest spleen, honey spleen, and insect spleen of the sick group, or turn wax or burn them.

**There are many larval disease drugs, such as sulfonamides, oxytetracycline, tetracycline, penicillin, streptomycin, erythromycin, etc. For example, 1000 grams of 1:1 sugar water, add 400,000 units of oxytetracycline or tetracycline, and feed 100 200 grams per group each time according to the strength of the group.

You can also feed 800,000 units of penicillin per stick, 1 million units of streptomycin per stick, and 300,000 units of erythromycin per stick, all of which are added to cold sugar water (hot sugar water is not available), 1:1 sugar water 1000 grams plus 1 stick, and each group is fed 200 grams each time, 1 time a day. Cretaceous disease can be used with chalk and used according to the instructions.

Cystic larval disease can be fed with viral, 1 tablet per frame of bees, dissolved in sugar water.

The rotten son should be changed three times, insist on feeding the strong group, the medicine can be searched on the **, chasing the bee No. 1, the effect is particularly good, and you can try it for free.
