Problem Prospective is the study of such an artificially grown Basidiomycete as Pleurotus ostreatus, which has pronounced antibacterial, antiviral and antioxidant activity, neuroprotective and antitumor effect. Drosophila melanogaster is a very convenient test object to assess the effects of biologically active substances obtained from P. ostreatus fruit bodies. It is convenient to examine the main indicators of viability and ontogenetic adaptation, such as fertility, reproductive activity, life expectancy, etc. for a short period of time on the fruit fly.Purpose The aim of the work was to study the effect of the biologically active substances of the powder from the P. ostreatus fruit bodies on the adaptability indicators of Drosophila melanogaster, such as fecundity, longevity and reproductive activity of flies.Results The fertility indices in the control and in the experiment on powdered oyster mushroom in nutrient medium in young and aging flies were studied. An increase in the fertility by the number of pupae in the experiment by 53 % compared to the control was observed in 15-18 day flies.Fertility of the Canton-S line flies increased from the second generation by 12-17 %, when powder from P. ostreatus fruit body was added to the nutrient mixture for 5 generations.Sexual behavior of flies was studied by the indicators of male sexual activity and sexual receptivity of females in the experiment and control in the parent forms F0 and descendants F1. An increase in the number of matings by 20 % was established, both for males and females.The lifespan of flies that fed on a nutrient mixture with the addition of powder from the fruit bodies of P. ostreatus over five generations increased more in females than in males.Conclusions Powder from P. ostreatus fruit bodies produces a tonic effect on the flies of the Canton-S line and improves the performance of all systems, which contributes to an increase in the longevity, fertility and reproductive activity of flies.
