Abstract:Heat emission by the honey-bee larvae, prepupae, and pupae was investigated by microelectrocalorimetry. A correlation between changes in the environment temperature and heat emission was found. Within the vital range of air temperature (29–37.5°C), an increase in temperature by 1° stimulated an average heat emission increase of 0.5 mW/g in the larvae, 0.05 mW/g in the prepupae, and 0.2 mW/g in the pupae. At the optimum air temperature (34 ± 1°C), the increase in the larval body mass was followed by that in the total heat emission, but the heat emission to body mass ratio dropped. In the pupae, heat emission grows toward the end of the postembryonic development, the lowest value being observed in the prepupae.
