What bee mites look like and how to control them

Bee mites, ectoparasitic mites of honey bees, reproduce in the hive throughout their lives. It lays eggs in the uncovered larval room, reproduces in the covered larval room, parasitizes on the larvae, pupae and adult bees, and absorbs hemolymph, resulting in the shortening of the life span of bees, the decline of collection power, and the production of bee products. Heavily affected colonies have a large number of larvae and pupae dying.

The newly hatched young bees are incomplete, the young bees crawl everywhere, and the colony is rapidly weakened.

Arthropoda, Chelicerae subphylum, Arachnida, Ticks, Mites.

The ontogeny of giant bee mites is divided into 3 stages, namely eggs, nymphs, and adult mites.

Both Chinese bees and Italian bees will have bee mites, which can be seen with the naked eye, and there are two kinds of large and small bee mites. Big bee mites are mainly parasitic on adult bees, absorbing bee body nutrition, will reduce the life span of bees, large bee mites breed and lay eggs mainly in the drone hive, so usually often cut off the drones in the drone hive, so as to effectively control the reproduction of large bee mites. Small bee mite is more harmful, can also be seen with the naked eye, small bee mite is mainly in the worker bee hive to lay eggs and reproduce, absorb the nutrition of worker bee larvae, so that the larvae are stunted, the worker bees harmed by small bee mites, lack of wings, missing feet, curly wings and other cripples when leaving the house, can not go out of the nest to collect nectar, seriously endanger the bee colony, when the small bee mite is serious, it can crawl on the spleen of the nest, visible to the naked eye.

Anti-mite drugs should be used promptly**.

Bee mite is the external parasite of bees, all their lives are reproduced in the hive room, the impact on the bee colony is very large, in the pollution-free control of bee mite, the selection of acaricidal drugs is the key to ensure that bee products are free from pollution, the drugs for the prevention and control of bee mites mainly include contact killers, fumigants, fumigants, etc.

Severed child extermination method.

Bee mites are mainly parasitic on bees as the carrier, so in the natural offspring period of bees is the most favorable and critical period to kill bee mites, when the queen bee has not yet begun to lay eggs, there is no capped young in the bee colony, and bee mites are mainly concentrated on the body surface of adult bees, the selection of efficient and non-polluting bee mite drugs to kill, can completely kill the hidden parasitic bee mites.

Artificial isolation method.

First, the spleen in the bee colony is isolated with a separator, and all the spleens in the nest box are transferred to the relay box, and the empty spleen is made up for the queen bee to lay eggs, and then replaced with a separator board instead of the separator board, after isolating the sub-spleen for about 24 days, the bee mites in the relay box are feathered out of the house with the worker bees, and they die because they cannot get food and no larvae as a breeding place, and the effective rate of killing mites by this method can be more than 90%.

Smoke treatment method.

In the evening, after the bees return to the nest, the standard box is used 3 4 grams for 1 time, and a piece of paper is spread at the bottom of the box when smoking, the nest door is sealed, and the smoke is smoked for 15 20 minutes, the nest door is opened to take out the residual ash, and the next morning the pad paper is withdrawn to gather the bee mites that fall on the paper and burn them, according to the degree of parasitism of bee mites, each group can be smoked 3 4 times in a row, and smoked once every 3 days.

Hanging medicine to treat mites.

Use a pushpin to fix the fumigation acaricidal tablets such as mite flutter between the second bee paths in the bee colony, hanging diagonally, and the dosage is 2 tablets for the strong bee colony, 1 tablet for the weak bee colony, 3 weeks for a course of treatment, because the fumigation acaricidal tablets have a long volatilization duration, and the bee mites that have come out of the house can be killed one after another, so the control effect is excellent, up to 100%.

The subject should want to ask bees how to control mites

First of all, prepare the appropriate amount of medicine, cardboard, etc.

and other useful items, then grind the medicine into powder, spread it on top of the prepared paper, put it in the bottom of the box in the evening, cover it with another piece of paper to prevent the bees from touching it, and pull out the paper inside the next day and clean it up. In this way, the mites can be removed.

Precautions for bee mite removal;

1. The number of times to use depends on the situation, if there are more mites, then treat it twice.

2. When using fumigants, it will be easy to hurt the young bees, so the colony where the young bees are out of the house should not be used.

3. In good condition, the mites should be eliminated quickly and humanely, and they cannot be left.

Some researchers are trying to isolate and grow bees that have natural antibodies to mites, and are experimenting with anti-mite compounds such as vegetable oils and certain anti-mite compounds secreted by bees in the hope of finding effective ways to deal with mites.

1. Bee species selection.

Different varieties of bees have different resistance to bee mites, take the Italian bee and the Chinese bee as an example, the resistance of the Italian bee to the bee mite is generally weak, but its mite resistance will be greatly enhanced after artificial breeding, so in the development of beekeeping, we should try to choose bee species with strong mite resistance, which can effectively reduce the possibility of bee mites.

2. Raise strong groups.

The stronger the swarm of bees, the stronger the resistance to the outside world, so raising a strong swarm is the most effective way to prevent bee mites, which is also the main reason why bee mites occur in spring, when the external conditions are suitable, the queen bee after wintering begins to lay a large number of eggs, but the swarm at this time is generally very weak, the worker bees can not effectively protect the larvae, and the worker bees can not effectively clean up after the occurrence of bee mites, which leads to a vicious circle, and the group will become weaker and weaker.

3. Natural breakage.

Bees have a natural breakage period in early spring (the queen bee has not yet produced) and late autumn (the queen bee stops production for winter), because the reproduction of bee mites depends on the bee larvae, and the adult mites cannot reproduce normally without bee larvae and adult mites, and at this time the adult mites are mostly parasitic on the body surface of the adult bees, so the natural breakoff period of the bee is the most favorable time to control bee mites.

Fourth, artificial breakage.

The principle is the same as the natural cut off to control bee mites, first of all, the queen bee is locked in the cage to prevent it from laying eggs, and then the nest in the egg worm spleen is all disposed of (don't be reluctant, these egg worm spleen is incomplete even if out of the room), adult mites will be less and less because there is no bee larvae for breeding places, and then open the prison cage after all the adult mites are dead and let the queen bee continue to lay eggs, this method is the most effective for bee colonies with serious damage to bee mites.

5. Drug prevention and treatment.

The control of bee mites can only be sprayed with corresponding drugs, such as metamidine solution and formic acid solution, which are the most commonly used drugs to treat bee mites. There are also sulfur and the like, which can be brought to treat bee mites, but the effect is not good. Because if there are young spleens in the bee colony, there will be bee mites parasitic in the nest, although the outside bee mites can be cured, and when the bee mites in the nest come out of the room, there will still be a lot of bee mites.

Therefore, if the effect is not good, it can only delay the development. The best way is to cut off the bee mites, and we must seize the opportunity to cut off the mites every year.

<><1. Hazards: bee mites are the main ectoparasites of bees, which mainly harm the bees and the three types of bees may be parasitized by bee mites, among which the life span of the queen bee will be greatly shortened after being parasitized by bee mites, and the sexual function of drones will be significantly reduced after being parasitized by bee mites.

2. **: Bee mites can be used with contact killers, fumigants, fumigants and other drugs, including No. 1 acaricide, No. 2 acaricide, quick acaricide, anti-mite No. 1, etc., fumigants mainly include mite flutter, sublimated sulfur, formic acid fumigant, sanitary ball, etc., fumigants mainly include acaricidal No. 2 paper tobacco, anti-mite fumigant, etc., but when using the drug** bee mites, we must avoid the resistance produced by bee mites.

3. Prevention: bee mites reproduce in the honey nest all their lives, lay eggs in the uncovered larval room, develop in the covered larval room, parasitize on the body surface of bee larvae, pupae and adult bees, the best time to prevent bee mites is the natural breakoff period, the reason is that the reproduction of bee mites is highly dependent on bee larvae, and bee mites can only live for 1 2 days without bee larvae.

To sum up, bee mites are the main ectoparasites of bees, mainly harming bees, especially the weak group is the most vulnerable, and when the bee colony is seriously damaged, it can be used with contact killers, fumigants, fumigants and other drugs**, but the reproduction of bee mites is highly dependent on bee larvae, and bee mites can only live for 1 2 days without bee larvae, so they can be prevented with drugs in time during the breakoff period of the bee colony.

(1) biological methods to prevent and control the main parasitic larvae of small bee mites, which can only survive for 1 2 days on the adult bee body, and can only survive for 10 days at most on the pupae body, we can use the weakness of the small bee mite, using the method of trapping the queen bee, and the artificial cut off (referring to the bee colony without larvae of all instars, no capped room) can effectively control the harm of small bee mites for at least 3 days.

Bright heat and strong mites. 2) Chemical methods of control The methods of controlling large bee mites are also effective against small bee mites. In addition, sublimated sulfur is also very effective in the control of small bee mites, the use method is: shake off the bees on the lid, and then wrap the sublimated sulfur powder with gauze and evenly apply it to the surface of the spleen.

Once every 7 10 days, each time every 10 boxes of bees with 3 grams of sublimated sulfur powder, 2 3 times in a row, pay attention to the sublimation sulfur to master the dosage, in case bee poisoning. Or sprinkle the sublimated sulfur powder on the bee road or frame beam, in order to better control the dosage, a certain amount of white flour or fine cornmeal can be mixed into the sublimated sulfur powder as a filler.

Small bee mites are more harmful to small bee larvae, and beekeepers have management skills to control small bee mites.

Bee mites are ectoparasites of honeybees and are the enemy of bee colonies. The victim bee colony is weakened, the lifespan is shortened, and the collection power is reduced. Young bees have mutilated wings and are unable to fly. As a result, the population rapidly declines, and even causes the entire group to be destroyed.

Especially in summer and autumn, mite infestation is the most likely to become a plague and must be prevented and controlled in time.

1.There are many drugs for drug prevention and treatment of mites, and the following two are introduced.

1) Dimite fumigant. The drug has a good poisoning effect on large and small bee mites, and is less affected by temperature, especially suitable for early spring and late autumn.
