Abstract
The relevance of studying how non-ionizing terahertz radiation (0.1–10 THz) affects the living organisms is determined by the recent development of modern technologies that use such radiation. The aim of our study was to establish the impact of terahertz radiation on successive generations of fruit flies. The effect of terahertz radiation on the survival ability and lifespan of the Oregon-R strain of Drosophila melanogaster proved to be divergent: at early life stage they were negative and neutral, at late stages - positive. The radiation-exposed female flies showed increasing survival capability during the second half of the life of imago. Males showed low-sensitivity to radiation. There was not noted any significant difference in developing dynamics and total number of offspring between the female flies that were exposed and that were not exposed to radiation. The results of the study practically did not depend on the gender and maturity stage of the irradiated oocytes.
