What are the common pests and diseases of bees? Are bees pests

There are many types of bee pests and diseases. In summary, there are infectious pests and diseases caused by biotic and abiotic factors, and non-infectious pests and diseases. Infectious pests and diseases are divided into infectious pests caused by pathogenic microorganisms and invasive pests and diseases caused by parasites according to different infection methods.

The main infectious pests and diseases of bees are:

1) Viral diseases.

The main ones are cystic larva disease, paralysis disease, bee pupal disease, cloud wing virus disease, Egyptian honey bee virus disease, etc.

2) Bacterial diseases.

The main ones are American larval putrid disease, European larval putrid disease, septicemia and paratyphoid fever.

3) spiroplasmosis.

There is mainly honey spiroplasmosis.

4) Mycoses.

There are mainly chalk, aflaturosis and queen ovary melanosis.

5) Protozoan diseases.

There are mainly honey bee sporidiosis, honey bee amebiasis and so on.

6) Parasitic mites.

There are mainly Var mites (giant bee mites), bright heat mites (small bee mites) and Wu's bee shield mites (tracheal mites) and so on.

7) Parasitic insects and nematodes.

There are mainly bee flies, humpback flies, corianders, round-headed flies, bee lice and nematodes.

The non-infectious pests and diseases of bees mainly include curl wing disease, frostbite larvae, egg blight, jujube flower disease, camellia poisoning, manna honey poisoning, pollen, nectar and pesticide poisoning.

In addition, according to the state of the diseased bees, bee diseases and pests mainly include oval diseases, larval diseases, bee pupal diseases, and adult bee diseases.

Common pests and diseases of bees are: 1. Cystic larval disease is a larval infection disease after hearing the name, after the pathogen infects the larvae, the larvae are outdoors, and the head of the worm is upturned, and the appearance looks like a boat, sac-shaped. This disease occurs in larvae, so there is no specific drug**, only to remove the queen bee from the hive, wait for the bees to clean up the pests and diseases, and then disinfect the hive can be solved.

2. There are two kinds of larval rot diseases: American larval rot disease and European larval rot disease. American larval rot disease is caused by larval Bacillus infection, the larvae die brown at the onset of the disease, with a fishy smell.

European larval rot disease is caused by honeycomb honey bee coccus infection, the larvae die in a spiral shape and have a foul smell, the same cleaning of dead bodies, disinfection, and medicine**. 3. Infection with bee coccus will cause the larvae to die, and the larvae will die or the surface will produce white berry silk, and finally it will turn into gray-white hard lumps. The treatment method is to replace the disinfected nest spleen in time, burn the old nest spleen, feed it with professional fungicide with syrup, and strengthen warmth and ventilation at the same time, which can be eliminated in about half a month.

4. Sporozoites parasitize in the stomach and intestines of bees, so that the digestive function of bees declines or disappears, and after a long time, the syrup eaten will expand the stomach and intestines, unable to fly, and it is best to die of exhaustion and weaken the bee colony. It can be eliminated by adding didrip to the syrup and feeding. 5. It is mainly parasitic on bees, and when it grows and matures, it lays eggs in the hive and sucks the body fluids of the larvae, causing the growth and development of the young bees after leaving the house, losing the ability to fly, and weakening the bee colony.

It can be sprayed regularly with a special acaricide.

Question 1: Are bees beneficial or pests Beneficial insects because bees help some plants spread pollen so that they can blossom and bear fruit. It also makes honey and beeswax for people.

Question 2: Are bees beneficial or pests Hello, there are two species: wasps and bees.

Honey bee Chinese bee, commonly known as earth bee. Soil honey is a honey made by soil bees collecting nectar from alpine forests and wild mountains. Honey has a deep color, unique taste, sweet taste, contains a variety of trace elements that can be directly absorbed by the human body, and is described in the "Compendium of Materia Medica" as having high value for human health, and is the first choice for medicinal honey, which can be called "the best in honey", and is also known as "the treasure of honey" because of the long honey brewing cycle and the scarcity of honey sources.

Hornets are beneficial insects, and they are usually "people don't offend me, I don't offend people", so don't poke hornet's nest indiscriminately. If residents want to remove the hornet's nest by themselves, they can take three methods: fire, smoke, and bag covering. Fire Clan:

Extend or lift the torch to the honeycomb; Smoke: smoke from burning grass or rice stalks to smoke wasps; Wrap your head and face in thick clothes and cover it with a woven bag or sack. If you are not sure, it is safer to ask the fire department to remove it.

They can pollinate flowers.

Question 3: Is bees pests or beneficial insects Hello, bees are beneficial insects, first of all, it is the main way to spread pollen, or it will not bear fruit without pollination, and secondly, honey is also beneficial to the human body, and drinking nectar often can also prevent constipation; Wasps are a kind of beneficial insects, to protect, otherwise the ecological environment will deteriorate, wasps feed on pests, so that the number of pests decreases, and contribute a lot to crops, raising a nest of wasps near the vegetable field can play a large role in eliminating pests, and then raise a nest of bumblebees, specially used to pollinate crops, so as to become a real green vegetable. If the hornet is nesting at home, you can block the exit of the hive in the weak light in the middle of the night when the hornet is completely returning to the nest, and then gently remove it and release the hive into the wild mountain forest with few people.

Question 4: Are bees beneficial to insects 5 points According to traditional thinking, bees are of course beneficial insects, providing honey, pollen, royal jelly and so on to human beings.

But personally, I believe that there is no certain boundary between good and bad, and the stakes will be different for different objects.

Question 5: Are bees beneficial or pests Bees transmit pollen and are beneficial insects.

Question 6: Are bees beneficial or pests? Bees are beneficial insects that can help plants spread pollen and increase yields.

Question 7: Are bees beneficial insects or pests Do beneficial insects spread pollination?

Question 8: Those bees are pests The main pests and diseases of bees are: The common pests and diseases of bees are mainly registered

American larvae rancid and European larvae rancid and cystic larvae and sporozoa and chalk and bee mites and nest worms, among others. Bee diseases and insect pests are based on the principle of "prevention first, prevention is more important than cure", through the adoption of perennial breeding and strong colonies, bee equipment disinfection, apiary cleaning and hygiene, and timely use of medicine.

Question 9: Are bees beneficial or pests Of course, they are beneficial insects.

Question 10: Are bees beneficial or pests Beneficial insects, the state is ruined because bees help some plants spread pollen so that they can bloom and bear fruit. It also makes honey and beeswax for people.

<><1. Cystic larval disease: cystic larval disease is caused by cystic larval virus, mainly harming older larvae, 30% die before the cap, 70% die after the cap, the dead larvae lie directly under the nest, the head is cocked, the body color first turns yellow-white and then turns brownish-yellow, the internal tissue liquefies and there are particles in the liquid, the lid of the sick and dead larvae sinks, and is mostly bitten or perforated by worker bees, and there is no specific drug.

2. Reptile bee disease: reptilian bee disease is caused by paralysis virus, sporozodia, spiroplasma, marhalbitan amoeba, etc., in the early stage of the disease group irritability, dysentery, poor spleen protection ability of worker bees, etc., in the middle of the worker bees are jumping flight, a large number of adult worker bees fall to the bottom of the box, and in the later stage, the worker bees completely lose their ability to fly, wriggling and crawling outside the nest door, and can be prevented and controlled by chlortetracycline attack brigade height, novomycin, sentinazole tablets, and sulfonamides in the heartburn.

3. Rotten disease: rotten disease is mainly caused by honeycomb bee coccus, followed by secondary bacteria such as Bacillus beehibi, Bacillus lateralis and mutant Honey bee streptococcus, which mainly harm bee larvae, and the diseased larvae mostly die when they are not covered at the age of 3 or 4 days, and when they are serious, they can smell a strange smell when they approach the bee farm, and at the same time, there is a flower phenomenon on the bee spleen and the larvae are different in age, which can be prevented and controlled by sulfonamides.

4. Sepsis: septicemia is caused by septicillus, the abdomen of the sick bee is distended, the body color is dark, the action is slow, and a large number of dead bees and the feces excreted by the sick bee can be seen in severe cases and emit a foul smell, the dead bee corpse becomes soft and black, and the limbs, head, chest, and wings are broken, which can be prevented and treated with antibiotics such as oxytetracycline and chloramphenicol, and 100,000 units of oxytetracycline or chloramphenicol per kilogram of syrup, and 50 100 grams per frame of bees.

5. Paratyphoid fever: paratyphoid fever is caused by Enterobacter hafni bees, the sick bees excrete a lot of viscous, semi-liquid dark brown feces, there is still enough feed in the beehive, but all are soiled by feces, the digestive tract of the sick bees can be seen intestinal swelling and grayish-white, can be prevented and controlled with cotrimoxazole and chloramphenicol, 1 2 grams of cotrimoxazole and 2 grams of chloramphenicol per kilogram of syrup, 50 100 grams per frame of bees.

6. Cretaceous disease: chalk disease is caused by the corpus saccharococcus, mainly harming the larvae, the diseased larvae are more than the death before and after the capping, the dead larvae are swollen and pale in the early stage, and the white lime with loose texture is after losing water in the later stage, when the disease is mild, the worker bee can still clean up the larval corpse out of the hive, and many white insect corpses can be seen in the nest when it is serious, and nystatin has a significant control effect on the disease.

To sum up, bee diseases include cystic larva disease, reptile bee disease, rot disease, septicaemia, paratyphoid fever, chalk disease, etc., among which reptilian bee disease, cystic larval disease, rot disease and so on are the most common, it is worth noting that many bee diseases are contagious, so after the disease is found, it should be isolated immediately and prevented.

When answering what symptoms the bees have, it means that the bees are sick, and generally speaking, if you encounter the following situations, you should pay attention to them. 1. Decay The pathogens that cause the decay of bee tissue cells include bacteria, fungi, viruses and mites; In addition, there is frost damage, food poisoning, etc. 2. Discoloration The body color of the diseased larvae changes from bright, shiny white to pale, then yellow, and finally black.

3. Reptile bees Due to the weakness of the bees or the damage to the nervous system due to pathogens, a large number of sick bees can be seen crawling at the bottom of the nest box or outside the nest box. 4. Deformity: mite damage or high and low temperature caused by wings, lack of wings, and abdominal distension caused by various reasons. 5. Trembling Adult bees cannot fly, their bodies tremble, and their wings tremble at the same time.

This symptom is more common in paralysis or pesticide poisoning. 6. Kiss out Bee snout out outside the mouth, mostly seen in dead bees, is generally considered to be a typical symptom of bee poisoning and spiroplasmosis.
