Abstract
Virgin drosophila females were stressed by placing them in a limited space without food for 3 h. Some of the flies were exposed to terahertz radiation for 30 min in the 0.1–2.2 THz frequency range. Irradiated and unirradiated flies were then mated with males. The F1 progeny of egg cells that were mature or immature at the time of radiation (laying at the first–second and ninth–tenth days after the radiation) were studied. The lifespan of separate individuals were registered. It was demonstrated that terahertz radiation has no effect on the average and absolute lifespan of F1 progeny of both sexes. Sexual dimorphism was found in the survival response to terahertz radiation. The survival curves of males that were developed from egg cells that were immature or mature at the time of radiation significantly differ from the appropriate control, while the survival curves for females are similar to the control. It was concluded that terahertz radiation has a longterm influence on the survival of F1 male progeny.
