What medicine is good for the treatment of large and small bee mites?

1. Hazard characteristics

Bee mites breed in the hive all their lives and live by sucking bee blood lymph, the larvae or pupae of all instars of the seriously damaged bee colony have a large number of deaths, the larvae are easy to decay and have no certain shape after death, the pupae can not be successfully feathered and the head is stretched out when dying, many deformed young bees can also be seen in front of the beehives, and the adult bees will be parasitized by bee mites The life span will be significantly shortened and susceptible to paralysis.

2. Life cycle

1. Large bee mites: large bee mite females sneak into the larval nest when the spleen is about to be capped, and begin to lay eggs two days after the capping, early nymphs appear on the third day, late nymphs appear on the seventh day, the second generation of adults appear on the tenth day, and adult mites go out of the room with the young bees on the twelfth day.

2. Small bee mites: small bee mites begin to lay eggs 45 52 hours after entering the bee larval room, the egg period is about 15 30 minutes, the larval stage is about 20 24 hours, the early stage is about 44 48 hours, and the late stage is about 48 52 hours, and the young bees go out of the room after maturity.

3. Commonly used drugs

1. Contact killer: Contact agent is an insecticide that causes poisoning by contacting the body surface of the giant bee mite and entering the insect body, commonly used are Acaricide No. 1, Acaricide No. 2, Quick Mites, Enemy Mites No. 1, etc.

2. Fumigant: Fumigant is an insecticide that causes poisoning and death of large bee mites due to smoke produced by combustion, and commonly used are "Acaricide No. 2" paper tobacco, dimite fumigant, etc.

3. Fumigant: Fumigant is an insecticide that uses drug volatilization to produce vapor to poison giant bee mites, commonly used mite flutter, sublimated sulfur, sanitary ball, formic acid fumigant, etc.

Fourth, the first method

1. Cutoff killing: bee mites are mainly parasitic with bees as the carrier, so the bee cutoff period is the most favorable and critical period to kill bee mites.

2. With bee spraying: bee mites can be sprayed with contact killers such as Acaricide No. 1 and Dimite No. 1, the specific method is to add water to prepare the contact killer into a spray, and then evenly spray it on the bee spleen and spray until there is a layer of mist on the surface of the bee's body, and then cover the beehive cover.

3. Hanging medicine fumigation: bee mites can be fumigated with fumigants such as mite pounce and formic acid, for example, the mite pounce can be hung diagonally between the second bee path, of which the strong group hangs 2 tablets, and the weak group only hangs 1 piece, and the general application of 2 3 weeks has obvious mite treatment effect.

5. Precautionary measures

1. Bee mites are reproduced by bee larvae, so the natural cut-off period is the most favorable period for preventing bee mites.

2. The epidemic and swarm potential of bee mites are one and the other, in fact, most of the bee colonies that are seriously harmed by bee mites are weak groups, so beekeeping production must raise strong groups and ensure that there are more bees in the beehive than the spleen.

3. Bee mites are directly related to the mite resistance of bee species, and attention should be paid to the selection of bee species with strong mite resistance in beekeeping production, and the queen bee should be replaced in time and gradually eliminated for bee species with weak mite resistance.

Contact killers, fumigants, fumigants can be used. These are all relatively good. Bee mites can be removed.

You can use Mitesicide No. 1, the effect of this medicine is particularly good, and it is also very small.

You can use the nest spleen of the Italian bee, this drug is very effective, it needs to be replaced every year, and it can only be used for a maximum of three years.

As follows:

In the early spring of the bee colony that overwinters the king of the prisoner, the king is released to multiply at the same time, and then a new mite is hung after 20 days. If you spray a mite water treatment agent (generally not used because of cold weather), spray it again after 2 days, which can kill the large bee mites that overwinter with the bee colony.

Before the autumn multiplication, about the beginning of August after the king was imprisoned for 10 days, the king was sprayed at the same time to treat mites with water agents, once every 3 days, sprayed four times in a row, the size of the bee mites hiding under the wax cover, will always be exposed to the spray, will inevitably be killed.

Ecological prevention and control. The offspring of large and small mites are sucked by the body fluids of bee larvae for nutrition, relying on the bee pupa wax cover for protection, and the bee colony for synchronous reproduction.

The different biological characteristics of large and small bee mites are: large mites can suck the body fluids of adult bees for nutrition, and can parasitize on adult bees for many years, while small bee mites can only live on bees for about two days.

The drugs for the prevention and control of bee mites mainly include contact killers (such as acaricide No. 1, quick killing mites, anti-mite No. 1, etc.) and fumigants (such as paper No. 2 smoke, dimetic fumigants, etc.), fumigants (such as mite flutter, sublimated sulfur, formic acid, etc.), in the selection should choose safe, non-polluting, non-residue high-efficiency bee mite drugs, such as acaricide No. 1, mite flutter, etc., and often use the same drug to control bee mites when it is easy to make bee mites resistant to the drug, so it should be used alternately.

<><1. Contact killer: Contact killer is an insecticide that causes poisoning by contacting the surface of the small bee mite body and entering the insect body, such as acaricide No. 1, acaricide No. 2, quick killing mite, dichloride No. 1, etc., the specific usage is to pour the drug into the sprayer and dilute it with water, and then spray it obliquely on the nest spleen to make the nest spleen show a layer of mist.

2. Fumigant: Fumigant is an insecticide that burns to produce smoke and cause poisoning and death of small bee mites, such as acaricidal No. 2 paper fumigant, dimetic fumigant, etc., the specific usage is to put the fumigant on the tile or other objects to ignite, and then close the nest door and cover the box lid for about 20 minutes.

3. Fumigant: Fumigant is an insecticide that uses the volatilization of the drug to produce vapor to poison small bee mites, such as mite flutter, sublimation sulfur, sanitary ball, formic acid fumigant, etc., the specific usage is to place the drug in the beehive, but the dose must be controlled, otherwise bees may also be poisoned.

To sum up, the small bee mite is the main ectoparasite of the bee, mainly harming the bee, the bee has a strong resistance to the small bee mite, the drugs for the prevention and control of the small bee mite mainly include the contact agent such as the acaricidal No. 1, the acaricidal No. 2, the anti-mite No. 1 fumigant, the anti-mite No. 2 paper tobacco, etc., and the fumigants such as the mite flutter, sublimation sulfur, formic acid and so on.

<>1. Hang the "mite flutter" high-efficiency anti-mite tablets in the hive, which can kill the big bee mites and small bee mites on the bee body and the hive spleen, and apply "sublimated sulfur" in the spleen of the cap, or use it together with drugs such as "anti-mite No. 1", so that the small bee mite can be completely controlled. 2. Claustrophobic the queen bee for 9 days, then open the larval room, shake the larvae out of the nest spleen, and the baby bee mites will die after 1-2 days.

First, the best way to beg bee mites

1. Method.

1) Hanging the "mite flutter" in the hive can kill the big bee mites and small bee mites on the bee body and the hive spleen, but the small bee mites in the cover nest are difficult to exterminate, so in order to make up for this shortcoming, you can also apply "sublimation sulfur" in the spleen of the cap, or use it together with drugs such as "dime no. 1" and "quick kill mite", so that it can play a role in thorough control.

2) Small bee mites can only survive for up to 10 days on the pupal body, and can only survive for 1-2 days on the bee body, and can not suck the hemolymph in the adult bee. The specific method is to claustrophobic the queen bee for 9 days, then open the lid larval room, and shake out all the larvae in the nest spleen.

2. Prevention methods.

1) Select bee species with strong mite resistance as the cultivation object, and bee species with weak mite resistance should replace the queen bee in time and gradually eliminate them.

2) Raise a strong group to ensure that the bees in the hive have excess spleen.

3) Use non-polluting acaricidal drugs during the natural offspring period to kill the small bee mites hidden in the beehive.

Second, what are the symptoms of small bee mite hazards?

1. Small bee mites can parasitize the body surface of bee larvae and adult bees, and bees at all stages of development will be harmed, when the larvae are dead and the bee pupae are parasitized, the larvae of all instars will die in large numbers, and a large number of young bees whose wings can not be stretched (or mutilated) can be seen in front of the beehive.

2. After the adult bee is parasitized by the wasp mite, its life span will be shortened, the collection power will be significantly reduced, and it is easy to be infected with the paralysis virus due to the piercing of the body.

3. Baby bee mites reproduce in the hive all their lives, and the female baby bee mites that enter the larval room will lay eggs within 45-52 hours, the egg period is about 15-30 minutes, the larval stage is about 20-24 hours, the early stage of the mite is about 44-48 hours, and the late stage of the mite is about 48-52 hours. When the baby bee mites mature, they will follow the new bees out of the house.
