[Research of Embryonic Mortality Stages of Drosophila melanogaster Depending on Age and Starvation of an Imago].

Influence of age of parents and duration of starvation on egg production and demonstration of embryonic mortality at different stages of egg development has been studied. It is shown that, with increasing age of organisms, the overall egg production reduces and the percentage of embryonic mortality increases at 0-5.5 and 5.5-17 h of development. An increase in the duration of starvation also promotes a reduction in egg production in 3- and 10-day-old adult D. melanogaster compared with short-term starvation. A statistically significant effect of factors, such as the allelic state of the white locus, the genetic background, the age of the parents, and the duration of starvation, on all studied parameters was established.
