The dissertation on the influence of temperature and humidity of the environment on the reproduction of the honey bee (Apis mellifera) describes the effect of the observed physical quantities on the entire bee during the growing season. Three habitats were monitored under different conditions. The measuring devices were always located inside and outside one colony of each habitat. In cooperation with colleagues from the Faculty of Electrical Engineering, ČVUT in Prague, the physical parameters monitoring was extended by monitoring the sound and weight of the hives - hive assemblies at the site located at the Agricultural Faculty of the University of South Bohemia. The data collection system in beehives was designed as a fully autonomous modular system. Measured data was processed and evaluated by statistical programs. The results showed that the hives observed differ in the number of bee queens found in the growing season and also in the number of frames found. Near-fetal temperatures were measured for correct development of the bee (32 °C to 36 °C). Colonies in the observed periods of 2014, 2015 and 2016 had to actively increase the relative humidity inside the hive in spring and summer. The colony reacts to changes in air temperature by varying intensity of sound. The results revealed the differences between the intensity of bee sounds in different temperature conditions. The highest sound intensity was detected at temperatures below 10 ° C (36.71 W.m-2), the lowest being at temperatures above 29.4 °C (26.25 W.m-2). The correlation coefficients were very low (r = 0.180) to medium (r = 0.463) and the correlation coefficient (r = 0.555) changed with a change in the temperature group. In order to evaluate the optimal conditions for honeybee rearing, the temperature and humidity monitoring can be used. The most suitable temperatures were in the range (29.5-34.3 °C) and temperatures above 34.4 °C. In terms of humidity, the temperature range (20-29.4 °C) and (29.5-34.3 °C) are the most appropriate. Changes in the observed values also affect the queen's bee in the colony. The data obtained from the long-term monitoring of these variables can help us to construct a THI index for bees, which would be a suitable tool to evaluate the optimal conditions for bees.
