About dynamics of temperature of the maximal overcooling and size of fatty body during wintering of honey bees

The author studied the dynamics of temperature of maximal overcooling (TMO) and change of the sizes of a fatty body in a belly department of wintering bees. It is revealed, that the size of a fatty body from the beginning of winter to spring decreases, to that there corresponds increase of average values TMO. However at bees with identical development of fatty body ТMO can differ essentially. It is connected to high variability of temperature of freezing of bees. It changes in process in nest migrations, going down under influence hippo-oxygen and trophic activation that occurs at localization in a zone of the thermal centre.
