PURPOSE: To investigate the effects of microwave frequency electromagnetic fields (EMF) on the development of Drosophila melanogaster.
MATERIALS AND METHODS: Larvae of D. melanogaster were exposed to 10 GHz EMF continuously (3 h, 4 h and 5 h) and discontinuously (3 h exposure + 30 min interval + 3 h exposure). The percentages and times of transition from larvae to pupae and from pupae to adults were determined, and the mean offspring number was examined using the offspring of the females which had been exposed as larvae.
RESULTS: No differences were found in the transition percentages from larvae to pupae and from pupae to adults (p>0.05). However, it was found that the mean pupation time was delayed linearly with an increasing electromagnetic field (EMF) exposure period (p<0.05). In the 3 + 3-h exposed group (E3 + 3), the mean offspring number was significantly less than that of the control (p<0.05).
CONCLUSIONS: 10 GHz EMF can cause developmental delay and decrease the number of offspring in D. melanogaster.
