Definitions

  • the invention relates to a method for controlling and killing parasitic Varroa mites in brood combs containing bee brood with a frame and capped brood cells by heat treatment of the brood combs, and a device for carrying out the method.
  • It is known to control the Varroa mites with chemical substances and to kill the mites.
  • the chemical substances have the disadvantage that they pass into the honey, which makes the use of chemical substances undesirable.
  • a thermal air-circulation method in combination with wintergreen oil is also known for controlling Varroa mites.
  • an extractor hood that can be placed on the beehive and equipped with a warm air blower is used, which is connected to the beehive's flight hole via a hose section for air return.
  • the brood combs are hung in a row in a closable container that is independent of the beehive, one behind the other in a row and exposed in the closed container to a fan air flow of 46 ° to 47 ° Celsius for a period of essentially 3 hours.
  • Brood combs can preferably be hung in parallel at a distance in succession in at least two rows one above the other in the container and exposed to the fan air flow of 46 ° to 47 ° Celsius over a period of substantially more than 3 hours in the closed container.
  • the process steps enable the latter to be killed quickly and safely outside the bee colony.
  • the procedure which can be carried out separately from the beehive, ensures that the treatment can be carried out over the entire length of the season without the risk of residues forming in honey and honeycomb and independent of traditional situations.
  • the method provides an effective control option without the use of chemicals, with the killed Varroa mites falling out of the cells of the brood comb when hatching the young bees.
  • a closable front-side container which accommodates an essentially U-shaped insert body which extends inside the container and is at a distance from the bottom wall, top wall and back wall and extends between the bottom wall, top wall and back wall of the container and the insert body forms a common air duct connected to the interior of the container and has air passage openings in the sections extending one above the other and in which a hot air blower is set at the bottom in the rear of the air duct as well as hanging registers on the side walls of the container for hanging and holding the brood comb frames vertically one behind the other or at a distance are arranged vertically one behind the other and one above the other.
  • the fan air flow can be guided as desired, for example without a pressure build-up in the interior of the container or with a pressure build-up in the interior of the container.
  • the latter can be easily achieved in that the air passage openings formed in the bottom section of the insert body are preferably designed according to a grid dimension have a larger overall cross-section than the air passage openings formed in the ceiling-side section of the insert body.
  • the air passage openings arranged in the bottom section of the insert body are expediently formed by a number of slits giving a grid pattern, while the air passage openings arranged in the ceiling section of the insert body are simply formed by the spaces between a grille set in this section.
  • An adjustable pressure build-up in the interior of the container can also be achieved in that the cross-sectional sizes of the air passage openings arranged in the ceiling-side and / or floor-side section of the insert body can be changed.
  • the bottom section of the insert body can be formed by a stationary insert body part and a wall part slidably over or under it, both of which have air passage openings which, when the position changes relative to one another, result in cross-sectional openings which can be changed for the fan air flow.
  • the air duct instead of an air duct vertically from bottom to top in the interior of the container, the air duct can also be made from through openings provided for the fan air flow in the bottom section of the insert body and the side walls of the container.
  • the arrangement of a cross-flow fan with an upstream or downstream one is preferred.
  • electrical heating register provided.
  • the cross-flow fan permits the use of a blower roller which extends at least approximately over the entire width of the interior of the container, thereby causing a uniform pressure figure and a uniform air outlet with low flow speed over the entire width of the container can be achieved.
  • relatively stable holding rails and, in particular, ledge bodies with slidably guided by rollers can be used with holding means for the brood comb frames.
  • the holding means can easily be formed by strip parts formed one above the other at a distance, the upper strip parts each having cutouts for receiving the brood honeycomb frames and the lower strip parts as support members for the brood honeycomb frames engaging under the upper strip parts continuously.
  • measures are provided which contribute to an optional location-dependent or location-independent use of the device by virtue of the fact that the container can be supported by rollers attached to the outside at the bottom and / or has carrying handles arranged on the outside of the container.
  • the rollers rigid foot parts can also be provided, which can be adjusted in height, if necessary.
  • the drive motor for the warm air blower and the heating register can either be designed for mains operation or can be applied to a low-voltage source, for example a rechargeable battery, for any location-based or location-independent use of the device. It is also conceivable to apply the drive motor and heating register to a light-dependent current-generating device.
  • the temperature of the interior of the container should be scanned and electronically controllable by at least one sensor and the heating register should the temperature rise in the interior of the container, be separable from the power source via an additional circuit, for example.
  • the relevant sensor is expediently set in the lower area of the duct for the fan air flow.
  • the heat treatment time of the brood combs can also be adjusted in an adjustable manner by means of a timer in the container. The latter leads to a particularly low amount of work when using the method and is also advantageous in connection with a cooling process, which begins after the heat treatment, of the interior of the container, which is initially closed over a period of time during automatic operation.
  • the device can be made from any materials, preferably a non-rusting material. Chromium-nickel steel connections have proven to be particularly suitable for this.
  • Fig. 1 shows a device with a closed mm container Cut
  • Fig. 2 shows a device with an open container
  • FIG. 3 shows a partial section of a hanging register enlarged, in perspective
  • Fig. 4 is a hanging file enlarged, in plan view and Fig. 5 is a partial section of the insert body. enlarged.
