Abstract
It is known that 20-hydroxyecdysone is one of the most important hormonal regulators of development, reproduction and adaptation to unfavorable conditions in insects. Here, we show for the first time that exogenous 20-hydroxyecdysone increases the content of two main insect carbohydrates, trehalose and glucose, in Drosophila melanogaster females both in normal conditions and under short-term heat stress. It is found that the levels of both trehalose and glucose increase after 39 min of heat exposure and return to their original levels after 1.5 h. A scheme of hormonal regulation of carbohydrate content under heat stress, involving 20-hydroxyecdysone, juvenile hormone, and dopamine, is suggested.
