Тривалість життя в імаго Drosophila melanogaster Meig. за впливу мікрохвильового опромінювання
Aim. The purpose of investigation was to study the effect of microwave irradiation of varying intensity to lifespan in adults of Drosophila melanogaster Meig. Methods. Experiments were carried out on wild type Oregon-R strain. Two-day-old flies were irradiated by microwaves (frequency – 36.64 GHz, exposure time – 10 sec). The power density was 0.01, 0.1 and 1 W/m2. Lifespan was examined in the irradiated and non-irradiated (control) flies. Results. The females showed a reduction in life expectancy by power density of 0.01 and 1 W/m2, median decreased respectively by 6.0 % and 8.7 % (p < 0.05). In males, reduced life expectancy was found by microwave power density of 1 W/m2, the median fell by 11.8 % (p < 0.05). No effect was detected by irradiation intensity of 0.1 W/m2. Conclusions. Exposure to microwave irradiation can reduce the lifespan in Drosophila adults. The effect depends on the sex and power density of microwaves.
