title: [Polymorphism of natural Drosophila melanogaster populations by level of juvenile hormone metabolism and reaction to heat stress].
abstract: The juvenile hormone metabolism in Drosophila melanogaster females from the laboratory line Canton S and from two natural populations of the Altaiskii krai was studied under normal conditions and under heat shock. The Canton S females were shown to have a high level of juvenile hormone and responded to heat shock by decreasing it. The natural populations were polymorphic for this trait. In both populations examined, flies with a low level of the hormone occurred at high frequencies (56 and 64%). The natural populations were also polymorphic for response of the system of juvenile hormone metabolism to heat shock: flies with a low level of the hormone did not respond to stress by decreasing it.
