A dispenser is disclosed. In one example, the dispenser relates to the distribution of formic acid vapour in beehives to combat mites. The dispenser has an evaporation surface which is delimited by a thin, gas-permeable, highly porous membrane made from a hydrophobic material and comprises an evaporation container and a reservoir, for the treatment dose of a liquid formic acid preparation. The evaporation container can be placed in a narrow air space of the hive, for example a comb space. The evaporation surface is exposed in a comb space of the brood nest or an air flow path. In one embodiment, the dispenser is equipped with a stackable packaging, and the treatment dose of the formic acid preparation is located exclusively in the hermetically sealed reservoir. The dispenser allows a very high evaporation rate per unit area and can be used without spatially extending the hive.

An insertable beehive entrance device allowing entrance into the beehive and disrupting exit from the beehive in order to make the moving of honey bee hives to a new location less problematic. The device includes a base with an entrance opening and a two legs attached to the base forming a triangular frame, the frame forming an entrance at its apex. The frame includes a mesh top covering and a reflective bottom covering configured to be brighter than the inner hive. Once placed in the hive entrance it allows honey bees to enter the hive through the insertable device but disrupts their normal pattern of exit. Bees are now trapped in the hive making it simpler to move. When catching honey bee swarms, this device placed in the entrance makes coming back for the swarm box more convenient.

Compositions and methods for protecting bees from toxins and for preventing or decreasing colony collapse are provided. The compositions comprise carbon microparticles which, when ingested by bees, increase their survival after exposure to toxins such as pesticides.

The present invention relates to shaped articles which are suitable for controlling Varroa mites in bees.

Provided herein are formulations and compositions to favor the selective pollination of blueberry crops throughout a mixture of compounds effective for the olfactory training of bees in such a manner that they get attracted to blueberry flowers. A method for promoting targeted pollination by honeybees towards blueberry crops which uses the formulations and the compositions of the invention is also described.

The group of inventions relates to beekeeping. A method is proposed to prevent honey bees from escaping the hive by cooling the air near the entrance to a temperature below 14° C. An appliance to prevent bees from escaping the hive consists of placed directly near the hive entrance a Peltier thermoelectric module with radiators that due to connection to a source of electricity can cool the air near the entrance to temperatures below 14° C. The inventions can be used to prevent honey bees from escaping the hive by the chemical tillage of crops or transportation and can improve the temperature conditions for the existence of bee colonies.
