[The age-dependent changes of reproductive function in offspring Drosophila melanogaster.].

It was analyzed a comparative study of age-dependent changes in the parameters of reproductive function and embryonic development of offspring from adults w1c-s, w1Or mutant strains and Canton-S, Oregon-R wild-type strains D. melanogaster. In investigation three age groups of adult drosophila: 3, 10 and 20-days old were used.

[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.
