“…The occurrence of genotoxicity dropped in the appliance, which is good because it is more important and related to daily life. No effect was detected on fecundity in our test, while in D. melanogaster females, Gonet et al [ 41 ] reported egg reduction by a 50 Hz magnetic field. Panagopoulos [ 42 ] demonstrated the influence of microwaves from mobile telephone radiation on the ovary, and hence reproduction ability [ 43 , 44 , 45 ], and Kesari et al [ 46 ] warned the risk of sperm decrease of males using the Wister rat under mobile-phone level radiation.…”

The physiological and behavioral influences of 2.45 GHz microwaves on Drosophila melanogaster were examined. Standing waves transitioned into heat energy effectively when passing through the insect body. On the contrary, travelling waves did not transit into heat energy in the insect body. This indicated that there was no concern regarding the thermal effects of microwave irradiation for levels of daily usage. However, we detected genotoxicity and behavioral alterations associated with travelling wave irradiation, which can be attributed to the non-thermal effects of the waves. Electron spin resonance (ESR) revealed that fruit flies possessed paramagnetic substances in the body such as Fe3+, Cu2+, Mn2+, and organic radicals. The temperature dependent intensities of these paramagnetic substances indicated that females possessed more of the components susceptible to electromagnetic waves than males, and the behavioral tests supported the differences between the sexes.

“…Embryonic development of invertebrate and vertebrate species can be disturbed by a variety of chemical and environmental stressors; therefore, it is not surprising that the possible influence on ELF EMF on embryogenesis was a subject of several studies (e.g. MA and CHU, 1993;MICHEL and GUTZEIT, 1999;GRAHAM et al, 2000;GONET et al, 2009;PANAGOPOULOS et al, 2013;DIMITRIJEVIĆ et al, 2014). Gametogenesis (especially oogenesis) and embryogenesis are a far more sensitive biological phase than the later developmental stages in all animals.…”

“…Gametogenesis (especially oogenesis) and embryogenesis are a far more sensitive biological phase than the later developmental stages in all animals. It was shown in experiments on D. melanogaster that ELF EMF exposure of developing follicles resulted in elimination of numbers of them, and a corresponding decrease in oviposition, while exposure of fertilized embryos (eggs) to the same fields did not cause a significant effect (PANAGOPOULOS and MARGARITIS, 2003;GONET et al, 2009). Similarly, we did not have significant differences between the control and the exposed group in early fecundity and egg-to-adult viability, when fertilized embryos were exposed to ELF EMF, but other studies with different experimental protocols detected a reduction in fecundity (GONET et al, 2009;PANAGOPOULOS et al, 2013;LI et al, 2013).…”

Over the past century, man-made electromagnetic fields (EMF) have changed the natural environment, representing one of the most common and rapidly increasing environmental factors as technology advances. Numerous studies of biological effects of exposure to EMF have been performed on Drosophila during the last 30 years, showing contrasting results. In an attempt to determine whether EMF exposures might affect the development of Drosophila, the present study examines phenotypic variations through direction and range of changes in several fitness components and wing length and width, of Drosophila subobscura isofemale lines, affected by 50 Hz EMF. Embryonal and early post-embryonal stages were exposed to homogeneous sinusoidal 0.25 mT EMF of 50 Hz. The EMF exposure caused a significantly prolonged developmental time and significantly increased the wing size with the opposite direction of directional asymmetry compared to the control group. These results shows that even such a weak EMF has the potential to modulate, through developmental pathways, some of the fitness-related traits, wing size, and wing asymmetry in D. subobscura even after one generation of exposure, showing that extremely low frequency (ELF) EMFs have relevant consequences on development, adult morphology, and fitness.

“…The effects of EMF exposure on insect morphology, physiology and behavior have been proved previously. The EMF exposure induced changes in: mosquito egg hatching (Pan and Liu 2004 ), ovipositon in Drosophila (Gonet et al 2009 ), locomotor activity of desert locust and American cockroach (Wyszkowska et al 2006 , 2016 ) or antioxidant defense in Baculum extradentatum (Todorović et al 2012 ). EMF exposure has been also shown to induce a release of octopamine—an insect ‘stress hormone’ in American cockroach (Wyszkowska et al 2006 ), whereas the static electric field exposure elevated octopamine levels in Drosophila brain (Newland et al 2015 ).…”

Exposure to electromagnetic field (EMF) induces physiological changes in organism that are observed at different levels—from biochemical processes to behavior. In this study, we evaluated the effect of EMF exposure (50 Hz, 7 mT) on cockroach’s response to noxious heat, measured as the latency to escape from high ambient temperature. We also measured the levels of lipid peroxidation and glutathione content as markers of oxidative balance in cockroaches exposed to EMF. Our results showed that exposure to EMF for 24, 72 h and 7 days significantly increases the latency to escape from noxious heat. Malondialdehyde (MDA) levels increased significantly after 24-h EMF exposure and remained elevated up to 7 days of exposure. Glutathione levels significantly declined in cockroaches exposed to EMF for 7 days. These results demonstrate that EMF exposure is a considerable stress factor that affects oxidative state and heat perception in American cockroach.
