Abstract: 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.

Abstract: Field of use: The invention relates to beekeeping, in particular to beehive designs. The essence of the invention: A right-angled opening is formed in the bottom of a multi-unit beehive, which has larger and smaller housings combined into the same frame, in which opening a filled smaller housing can be mounted, and a brood nest is further expanded by filling a larger housing with the required number of frames. The technical result: An improvement of the expansion conditions of the bee nest by it not being necessary to completely dismantle the small housing and by it being possible to add the required number of frames for the expansion of a larger housing.
