Деякі онтогенетичні аспекти впливу фізичних факторів на показники життєздатності у Drosophila melanogaster
Aim. The aim of this work was to study the effects of electromagnetic factors at preembryonic and embryonic stages on viability of aging parents’ progeny in Drosophila. The infl uence of microwave irradiation (MW, f = 36,64 GHz, surface power density at the level of the object — 120 ± 0,05 mW/cm2...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Aim. The aim of this work was to study the effects of electromagnetic factors at preembryonic and embryonic stages on
viability of aging parents’ progeny in Drosophila. The infl uence of microwave irradiation (MW, f = 36,64 GHz, surface
power density at the level of the object — 120 ± 0,05 mW/cm2
; 15 cm from antenna edge; exposure time — 30 s), magnetic
fi eld (MF; 25mT; exposure time 5 min) and their combinations (MW+MF and MF+MW) on rate of development; fecundity,
embryonic and pupal lethality in Drosophila melanogaster stock Canton-S was investigated. Methods. The methods of
recording of quantitative traits (rate of development; fecundity, embryonic and pupal lethality) and variation statistics
were used. Results. The exposure to physical factors at embryonic stages the increase of Drosophila rate development
was shown. MW also induced increasing pupal lethality being applied at embryonic stages. The MW+MF and MF+MW
exposure of young fl ies raised embryonic lethality in progeny of the oldest parents. Exposure of imagoes to MW only
resulted in increasing of pupal lethality of progeny. Conclusions. Electromagnetic factors that have been studied in this
work signifi cantly modify the viability of Drosophila. These effects depend on both developmental stage at which the
irradiation was applied and on parental age.
