Terahertz radiation improves adaptation characteristics in <Emphasis Type="Italic">Drosophila melanogaster</Emphasis>

An investigation into the effect of nonionizing terahertz radiation (0.1–10 THz) on living organisms is urgent due to the recent development of modern technologies employing such radiation. The aim of this study was to establish the impact of terahertz radiation on successive generations of fruit flies. The effects of terahertz radiation on the survival ability and lifespan of the Oregon-R strain of Drosophila melanogaster proved to be diverse: they were negative or neutral at early life stages and positive at late stages. The female flies exposed to the radiation showed increased survival rate during the second half of the life of imago. The males demonstrated low sensitivity to the radiation. There were no significant differences noted in the dynamics of maturation and total number of offspring between the female flies that were exposed to the radiation and those that were not. The results of the study practically did not depend on the sex and maturity stage of the oocytes irradiated.
