Purpose: Extremely low frequency (ELF) magnetic fields are essential
ecological factors which may induce changes in many organisms. The aim
of this study was to examine the effects in Drosophila subobscura
exposed for 48 h to ELF magnetic field (50 Hz, 0.5 mT) at different
developmental stages.
Materials and methods: Egg-first instar larvae developmental stage of D.
subobscura isofemale lines was exposed to ELF magnetic field, and
fitness components (developmental time, developmental dynamics,
viability and sex ratio) and locomotor activity of three-day-old males
and females were monitored. Also, just eclosed D. subobscura isofemale
adults were exposed to ELF magnetic field and their locomotor activity
was monitored just after.
Results: ELF magnetic field shortens developmental time, increases
viability and does not affect sex ratio of D. subobscura. No matter
which developmental stage is exposed, ELF magnetic field significantly
decreases locomotor activity of adult flies, but after exposure of just
eclosed adults observed change lasts longer.
Conclusions: Applied ELF magnetic field modifies fitness components and
locomotor activity of D. subobscura. Observed effects can be attributed
to the influence of magnetic field on different stages of development
where the hormonal and nervous systems play important role in the
control of examined parameters.
