After exposure to thermal stress or a control temperature, the relative abundance of ecdysone (E) and 20-hydroxyecdysone (20E) was measured in a wild-type line of Drosophila virilis (101) that is stress responsive and in a mutant line (147) that is not stress responsive. In line 101, the 20E content was higher and E content lower in females than in males. The abundance of E and 20E in females of line 147 was significantly higher than that in females of line 101. Females of line 101 were found to respond to 60 min of heat stress (38°C) by an increase in the abundance of both E and 20E, while in males of this line the amount of 20E increased and that of E declined. A role of the ecdysteroids in the control of reproduction of D. virilis under stress is discussed.
