Abstract

The invention provides a method for preventing and controlling bee mites, which is characterized in that mites are in a low-oxygen environment for a period of time, so that the mites cannot reproduce or the reproduction rate is reduced, or the mite reproduction is virtually failed, so that mite populations gradually disappear, and bees can survive.

Claims (10)

  1. 1. A method for controlling mites of bees, which is characterized in that mites are kept in a low-oxygen environment for a period of time, the mites cannot reproduce or the reproduction rate is reduced, or the mite reproduction is virtually failed, so that the mite population gradually disappears, and bees can survive.
  2. 2. The method of claim 1, wherein the low oxygen environment is such that the oxygen mass concentration is 0-19%, or 0-19% by volume, or the oxygen partial pressure is 0-19 kPa.
  3. 3. The method of claim 2, wherein the oxygen mass concentration is between 10% and 17%, or between 13.5 and 15 kPa% oxygen partial pressure, or between 9-17% by volume.
  4. 4. The method of claim 1, wherein the duration is from 12 hours to 30 days.
  5. 5. The method of claim 1, wherein the setting of the hypoxic environment comprises moving the bee colony to a hypoxic region at an altitude of 3000 m or more, so that the breeding of mites fails and the mite colony disappears gradually.
  6. 6. The method of claim 1, wherein the setting hypoxia comprises placing the population into a hypoxia chamber such that the population fails to reproduce, thereby allowing the population to fade.
  7. 7. The method of claim 6, wherein the method of generating hypoxia in the hypoxic chamber comprises one or more of generating a negative pressure in the chamber, introducing a non-oxygen gas, or a gas containing a low concentration of oxygen.
  8. 8. The method of claim 7 wherein the cavity is a hive containing a frame or a sealed room.
  9. 9. The method of claim 8, wherein the non-oxygen gas comprises an inert gas, carbon dioxide gas, and the low concentration oxygen gas mixture comprises a low oxygen concentration inert gas.
  10. 10. The method of claim 1, wherein the mites are heat Li Man.

Description

Method for preventing and controlling bee mites The invention claims priority from China prior application, application number 202511107810.1, 2025, 8, 202511107812.0, 2025, 8, and the entire contents of which, including but not limited to the abstract, drawings, claims and description, are incorporated by reference as if fully set forth herein. Technical Field The invention belongs to the field of bee keeping, relates to a method for preventing and controlling mites and application thereof, and in particular relates to a method and equipment for controlling and endangering bee mites. Background Bee (APIS MELLIFERA) is currently the most important commercial pollinating insect worldwide, in part because of the global decline of land insects. Currently 9200 million bees are estimated to be the major contributor to the annual global value of the dollar pollination service of 2350 to 5770 billion. China has over 600 thousands of groups of western bees, producing about 45 ten thousand tons of honey per year. However, one of the major pests affecting or jeopardizing the life of bees is mites. The main mites affecting the life of bees are varroa destructor (Varroa destructor), commonly known as "varroa mites", and the other is heat Li Man (Tropilaelaps), commonly known as "varroa mites". The original host of varroa destructor is an eastern bee, and the parasitic western bee after the host migration occurs and spreads to almost all bee-keeping areas, so that the parasitic western bee becomes the most serious pest and disease damage faced by the western bee industry worldwide. The bee body constitution infected by varroa destructor is reduced, even malformation occurs, and the bee colony can show a series of symptoms. It is also the carrier and transmitter of many pathogens. Co-infection of varroa mites and multiple pathogens is more damaging than infection of any single pathogen, and can cause devastating injury to the colony. If the bee colony does not have a periodic mite control scheme, most of the bee colony in the temperate zone area collapses in 2-3 years, and the bee colony in the area can die in a large area when serious. The western bees have no resistance to varroa destructor, the varroa destructor can be greatly bred in the bee colony, and the bee colony health is seriously endangered after the number of varroa destructor exceeds a certain number. The varroa destructor life history is divided into two phases, namely a carrying period of parasitic adult bees and a breeding period of parasitic bee pupae. In the stage of the carrier period, varroa destructor is mainly parasitic in the abdomen internode or chest and back of adult bees, accumulates nutrition and is prepared for the breeding period. In the breeding period of parasitic bee pupae, varroa destructor enters a nest when a bee larva approaches to a cover, and after the cover is closed, about 60 h eggs are laid down, and then next eggs are laid every 30: 30 h. The first egg is typically haploid and develops to male, while the remaining eggs are diploid and develop to female. As offspring females develop mature, the siblings mate. When bees emerge from the house, the female mites and the offspring thereof leave the house along with the adult bees, but only the female mites and the female mites which have completed mating can continue to harm the bees. When the varroa destructor is parasitic in a western bee worker honeycomb house or a drone honeycomb house, 2-3 or 3-4 mature varroa destructor can be produced in one breeding period respectively. The capping period of the hive house of the western bee worker and the capping period of the hive house of the drone are respectively 12 d and 14 d, and the breeding period of adult female mites on adult bees is added, so that the bee mites can finish a breeding period at the fastest speed of about 15 d. In the breeding process, adult female mites and their offspring ingest on bee pupae, seriously affecting the development and health of the bee pupae. In summary, it can be seen that the breeding process is critical for the hazard of varroa destructor. Interfering with the breeding process of varroa destructor is an important strategy for controlling varroa destructor. The genus heat Li Man is an in vitro parasitic mite of bees belonging to the phylum arthropoda, arachnida, subclass acarina, phylum consisiting mites, general dermatophagoides pteronyssinus. The bee colony is widely parasitic in western bees in China, and particularly in the area with short overwintering period, the bee colony is more seriously damaged. The heat Li Man survives by sucking up the hemolymph (blood) or fat body of the bee larva or pupa, and spends most of the time in the closed cell, and only 1-2 days outside the cell. The breeding period is highly matched with the bee capping period, 1-3 offspring are produced in each breeding period, and two generations can be produced in about 25 days, so that the breeding speed is high. The bee
