Bees die inexplicably, and bees die at home for no reason

Probably poisoned.

1. Pesticide poisoning. It is caused by the spraying of pesticides and chemicals on crops, fruit trees, forest trees and other plants by various pests, mites and diseases. Especially during the flowering season of honey pollen source plants, when the poisoning is severe, a large number of dead or dying bees appear at the bottom of the front and bottom of the beehive door.

The stronger the colony, the more dead bees. Dead bees are mostly gathering bees, and some have pollen masses on their legs. Symptoms of poisoning are death, with the wings open, the abdomen hooked, and the snout outstretched.

In warm and sunny weather, bees are chaotic and stinging, spinning and flying in the air or rolling on the ground. During the spleen lifting examination, more bees attached to the bottom of the box and were unable to attach to the spleen.

Pesticide poisoning prevention and control method: Before applying pesticides, relocate the bee colony to a distance of 3 kilometers from the application site. If the long-term effect of the pesticide does not exceed 48 hours, and the bee colony cannot be removed for a while, the bee colony can be claustrophobic.

During the claustrophobic period, it is necessary to do a good job of ventilation and cooling, keep the colony dark and quiet, and ensure that there is sufficient feed. It is only the collecting bees that have died of poisoning, and the nest is equipped with any poisonous nectar and flowers, and there is sufficient non-toxic feed in the box, it can be disposed of. If the young bees and feeding bees are also poisoned and die, they should be relocated, remove all the feed mixed with poisons in the colony, immediately feed thin syrup or licorice water syrup, and feed some corresponding antidotes.

2. Feed poisoning.

1. Nectar poisoning. In nature, there are a few plants that secrete nectar that can cause bee poisoning symptoms, which are manifested as adult bees convulsions, tumbling, abdominal distention, inability to fly, crawl out of the nest door, and finally spasm to death. Piles of dead bees are common in front of the nest and around nectar-flowing plants.

Newly released young bees will become paralyzed. Weakness crawls on the ground, wings twist and wrinkle, and symptoms of poisoning often appear during the flowering period and disappear with the end of the flowering period.

2. Pollen poisoning. The symptoms are basically similar to those of nectar poisoning. The difference is that the pollen-poisoned bee intestines are filled with pollen, and the poisoning continues until the pollen on the nest spleen is exhausted.

3. Manna honey poisoning. Some plants do not produce toxic pollen or nectar on their own, but bees collect large amounts of sugar juice secreted by parasitic aphids and scale insects, which contain more minerals and dextrin substances, which are difficult for bees to digest and poison. Worker bees have swollen abdomen and lose the ability to fly, often crawling on the frame beam or outside the nest door, sometimes forming small clumps on the grass near the beehive, and the honey sacs of the dead worker bees are enlarged into balls, and the midgut is grayish-white, with black flocculent precipitation inside, and black feces in the hindgut.

Prevention and control: First of all, beekeepers should have a certain understanding of the surrounding nectar sources, and do not build apiaries near toxic nectar plant sources. Secondly, in poor honey harvest years, it is always necessary to keep sufficient feed in the hive.

In addition, when the weather is particularly dry, it is necessary to feed thin syrup water frequently to maintain a suitable temperature in the beehive. For the feed poisoning colony, the feed spleen in the group must be withdrawn, the feed spleen must be re-fed, the spleen should be tightened, and the spleen should be strengthened with normal colony spleen and bees. If possible, the apiary should be relocated to another nectar source for breeding.

This is bee poisoning, do you have a lot of vegetable farming and fruit tree farming in your vicinity? Because spring is the time when pesticides are used in large quantities for fruit trees and vegetables;

You'd better take a look around, the effect on the colony is simply too great; Therefore, you must pay attention to the location of the nectar source; Be sure to avoid it;

My family is a beekeeper, so we are very careful, and we usually go to the neighborhood to investigate clearly;

Indigestion doesn't die so fast, is it a reptilian bee? That wouldn't have died that much in a day or two? Only poisoning will die in a day then. Try spraying some atropine, it can be poisoned.

Hello dear! The causes of bee death are as follows: 1- Natural death.

Natural death is the normal death of bees, but in general, even if it is overwintering, the mortality rate of bees is maintained at a normal level, that is, a wintering colony with normal ridges is not likely to have a large number of deaths in winter. Second: cold death.

This situation is easy to appear in some small and medium-sized groups, due to the small number of bees and the lack of experience of beekeepers, resulting in the third cold death of bees: heat death. It is a fact that bees are afraid of talking about the cold in winter, but bees are also prone to heat injury in winter due to excessive heat insulation, and bees suffocate to death.

Fourth: starvation. This situation is more common, mainly reflected in the beekeeper does not have a reasonable plan for bee wintering.

The greatest possibility is pesticide poisoning.

This is the most likely cause of the sudden mass death of bees. When this happens, we often find that the dead bee head dies at the door of the hive with the bellows, and some bees also carry pollen on their legs, which can be basically judged as pesticide poisoning.

For the sudden mass death of bees, there are nothing more than two causes, one is internal and the other is external. The internal causes are very complex, the resistance of the bee colony is low, and if it is infected with the virus, it will be wiped out if it is not in time. The external cause is poisoning, which is the most common case, because the flowering period is often accompanied by the spraying of pesticides, which can also lead to large numbers of bees if not careful.

If there is no nectar source in the outside world, it is necessary to consider whether the white sugar fed is caused by poor quality. There are probably two reasons for the mass death of bees.

There are many reasons for the mass death of bees, which may be caused by unsuitable temperature, especially before winter, weak bees or bees who go out to collect honey for a long time will die of exhaustion or freeze to death due to physical exhaustion.

It may be that there are some problems in the living environment, so I suggest you take a look at what the situation is?

A large number of bees may have collected toxic pollen, or it may be that too much jujube nectar was collected when the jujube flowers were flowing with honey, and then the jujube flowers were poisoned.

Under normal circumstances, bees are approaching winter, and the bee mortality rate is slightly higher, which is understandable, after all, from spring to autumn, bees work hard to collect honey, and it is time to die.

However, if there are a large number of deaths, there is a problem. It is likely that most of them die of illness and starvation, and under normal circumstances, the bees will clean the inside of the box by themselves, if they don't clean it, your bees have a problem, take a closer look to see if there is a lack of sugar or whether the bees are sick. It is necessary to pay attention to the work of mite prevention and disease prevention before the bees overwinter, and prepare food for the bees for wintering.

Or if you have honey in your hive, other bees want to steal sugar in your hive, and fight to death, in this case, there should also be dead bees outside your beehive, and you will see bees fighting.

Carefully observe whether it is pesticide poisoning.

It's cold, so it's possible that your life has come to an end!

Why do bees die during wintering? What is the solution?

Hello! Can you tell me why bees are dying in large numbers?

My curiosity stemmed from the death of a bee. It landed right next to my pot and when I found it, it was motionless.

On weekdays, my screen window is closed, and I can't see a place where bees can fly in. And when you think that the bee is going to great lengths with all her might, it must be here to find a place that makes it yearn for it. So, my eyes fell on this secret jungle full of flower pots.

This is my secret jungle. Three and a half weeks ago, I bought a packet of seeds from the Internet, and the advertising slogan was "Wildflower Combination, Grow Easily", which met my need to appreciate different kinds of flowers without having to work hard. Three days after I sowed the seeds, there were tender little green shoots that washed out of the soil, and I watered them every day and went out to see them.

Slowly, the seedlings grew from one to two, and then filled the entire pot.

I'm looking at the bees and staring at my pots, what the hell am I planting? I picked up my mobile phone, used flower and grass recognition software, took pictures and scanned identification, there are asparagus, small split, centella asiatica, autumn ying, plantain, elm, and there is actually an invasive plant called silver gum chrysanthemum, which is native to the United States and northern Mexico, and was collected in Yunnan in 1926. The point is that it may cause discomfort to people and harm health.

I was suddenly frightened, and I actually had a poisonous plant at home, and I hurriedly cut them down and eradicated them, causing damage to other plants that were growing in the pot. But it's better to kill a thousand by mistake than to let one go. The densely growing asparagus and others were simply uprooted, leaving only large-leaved centella asiatica in the pot.

My secret jungle is gone.

Later, I learned that the death of bees actually had nothing to do with plants. It flew in and was already crumbling, and I don't know the antecedents, only that it landed there.

I consulted my botany teacher, and he said that this invasive plant, after so many years, does not seem to be famous, and the pollen of the Asteraceae plant will cause allergies in some people, but it is not a big problem. My tense mood finally relaxed. The potted plants haven't bloomed yet, so I'm not too nervous.

And just a moment ago, I was almost about to complain, and I might have called the Animal and Plant Prevention Institute or the quarantine station, and maybe wrote a letter to the Institute of Botany of the Chinese Academy of Sciences, because I insisted that I found that the invasive species of Guess Rock was actually being sold, and that it would harm human beings if it continued.

The death of the bee made me experience panic, anger, and sudden emotional changes. How much you know affects your judgment, your behavior. Or you don't know anything, and still happily watch it grow every day, feeling the greatness of life, the magic of the sun and the earth.

Either you know everything, and the comprehensiveness of knowledge allows you to have a correct understanding. The most fearful thing is that I know a little bit and think that I have discovered the whole world.

Hello, the death of bees caused by the temperature difference effect.

In winter, the outside temperature is low, and the bees will basically not go to work, but once the outside heats up, there will be bees going out to collect honey, and after going out, a gust of north wind suddenly comes, or the temperature drops suddenly, the bees will lie there and not move, enter the "hibernation" mode, and finally die in its "hibernation" position; However, if the temperature rises the next day, some bees may still be rescued, which is why we often see bees at the door of the nest "returning to the sun" the next day.

It's not just beehives that die due to the temperature difference effect.

There is a phenomenon of dead bees at the door, and we often see dead bees on top of the honey source.

These are caused by sudden changes in temperature, and we generally take two attitudes to deal with this phenomenon:

Go with the flow; If you want to collect winter honey, it is normal to pay a price.

The most common way to interfere with and hinder bees from going out is to close the nest door; Only after looking at the weather forecast.

Make sure there is no sudden change in weather throughout the day before the bees come out.

Second, the reason for the lack of resistance of the bees themselves.

There are more bees in the strong colony and few bees in the weak colony.

The probability of death of the Italian bee is high, and the probability of the middle bee is less.

The reason for this law is that listening to the words of bees summarizes the problem of the bee's own resistance:

The weak bees have basically experienced the test of survival, so the damned bees are all dead, and the bees that remain and do not die are all in good health. The strong swarm has not undergone the "baptism" of the elimination mechanism, so there will be "old" and "weak" worker bees in it.

These bees have poor ability to cope with the external environment in winter, so it is more common for bees to die on the nectar source and at the door of the nest when they go out to collect honey.

The cold resistance of the Italian bee itself is worse than that of the medium bee, so the loss of honey collection in winter will be very large. There are many more bees that die at the door of the nest and outside than the bees in the middle bees. Migrate away from the colony and return after a while.

Bees will die in about 4 hours of light, bees are phototaxis animals, turn on the lights at night, bees will keep flying around the light source, if you don't turn off the lights, bees will die because of the physical exhaustion of flying all the time.
