[Dynamics of Reaching Imago Stage by F1 Animals after Terahertz Irradiation of Parental Drosophila].

Abstract

Terahertz radiation (0.1–10 THz) is increasingly becoming a factor of human habitat. The study of the consequences of radiation allows one to estimate its possible biological danger. Our data indicate that the terahertz irradiation of parental Drosophila shortens the period of embryonic development of their first generation descendants. Significant deviations of data from the control were found, when both females and males were experimental parents. The highest portion of animals with accelerated hatching as compared with the control was found in progenies from irradiated females. The shift of maximal hatching peak to an earlier period was found in descendants of both sexes. Thus, it was for the first time found on the model object (Drosophila) that the terahertz irradiation of parents can have positive or negative consequences in the first generation descendants.
