Specifically, the invention provides for the treatment or prevention of European or American foulbrood or chalkbrood. In addition, the invention provides methods for controlling Varroa mites that can weaken a hive or act as vectors for bacterial diseases. In further embodiments, the invention provides for the treatment or prevention of hive infestations with Lepidopteran pests, such as the wax moth (Galleria mellonella).

The invention concerns a composition for the treatment of varroa mite infestations in honeybee colonies, comprising a base layer and an active layer, wherein the active layer comprises an effective amount of an acaricidal compound.

The present invention is a method of controlling pests, such as the Varroa mite, tracheal mites, and the small hive beetle, in bee-hives or other desired locations comprising extracting plant essential oils from the Diphysa robinoides and applying an effective amount of the extract as a vapor to a desired area of a bee-hive.

The invention discloses a high-yielding cultivation method for bees, and relates to the technical field of insect cultivation.

The device and method for collecting and preventing the large bee mite in the bee colony of the present invention, wherein the device of the present invention includes a bee feeder; a bee collection box, the inlet of the top of the bee collection box is matched with the bee outlet, and the bee collection box The bottom is provided with a first screen; the bee mite collection box is provided with a second screen at the bottom of the bee mite collection box; and the powder recovery box. The method of the present invention includes: shaking the worker bees into the bee feeder, and shaking the bees into the bee collection box; after the bees enter the bee collection box, remove the bee feeder, sprinkle corn flour or powdered sugar, and cover the cover; Bee collection box, make the bee mites and corn flour or powdered sugar fall into the bee mite collection box; sift the corn flour or sugar powder into the powder recovery box. The device for collecting and preventing the giant bee mite in the bee colony of the present invention can conveniently and quickly collect the bee mite parasitic on the worker bee body in the bee colony. The method for collecting and preventing the large bee mite in the bee colony of the present invention can reduce the application of chemical acaricides, effectively reduce the poison to bees and reduce the drug residue in bee products.

The invention relates to a device for combating the varroa mite in a bee brood, comprising at least one middle wall that can be inserted in particular into a beehive and that is provided with brood cells for female bees, the device having an electrical heating device that has a resistance heating element embedded in the middle wall and a control device connected to the latter which is designed such that an automatically running heating process can be initiated with a temporally pre-determined heat-up phase that lasts until a temperature of 39° C. to 45° C., preferably 39° C. to 42° C., is reached at the bottom of the brood cells in the region of the resistance heating element and then with a subsequent phase of maintaining this temperature for a predetermined period of time.

The invention provides a medicine for preventing and controlling varroa destructors. The medicine is rosewood heart wood essential oil, and is prepared according to a method for extracting volatile oil in Chinese Pharmacopoeia (2010 version). The medicine is put on filter paper of bee hives and acts on bees and the varroa destructors by natural volatilization to achieve an effect of preventing and controlling the varroa destructors of the bees, wherein the using amount of the rosewood heart wood essential oil in each bee hive is between 0.5 and 10 millimeters. A method for preventing and controlling the varroa destructors has a good effect of killing the varroa destructors and is low in toxicity on the bees, and the bees are not hurt while the varroa destructors are killed; the medicine is wide in source, easy to prepare, convenient to use, and high in volatility, and is particularly suitable for preventing and controlling the varroa destructors by fumigation.

The bee washing system washes worker bees and filters out varroa mites so that a beekeeper/operator can estimate the number of infected bees in a hive. The system includes a bee containment section with a coarse mesh filter, and a wash material section with a fine mesh filter. The system is structured so that when the bee containment section is loaded with bees, and the wash material section is loaded with wash material, an operator washes the bees by shaking the system. When the wash is complete, the operator detaches the wash material section from the system and counts the mites present on the fine mesh filter.
