Abstract
The effect of 20-hydroxyecdysone (20E) and the juvenile hormone (JH) on the activity of the alkaline phosphatase (ALP) has been studied in young females of wild-type Drosophila virilis and Drosophila melanogaster under normal conditions and under heat stress (38 degrees C). Both 20E feeding of the flies and JH application led to a substantial rise in ALP activity. ALP activity was also measured in young females of a JH-deficient strain of D. melanogaster, apterous(56f). A decrease in the enzyme activity was observed in the mutant females as compared to wild type. A rise in JH and 20E levels was found not to prevent the response of ALP to heat stress, but to change its stress-reactivity. Mechanisms of regulation of dopamine (DA) level by gonadotropins in Drosophila are discussed.Entities:
