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.
电磁场（EMF）暴露会引起生物体的生理变化，这些变化可以在不同的水平上观察到，从生化过程到行为。在这项研究中，我们评估了电磁场暴露（50Hz，7mT）对蟑螂对有害热的反应的影响，以从高温环境中逃脱的潜伏期来衡量。我们还测量了脂质过氧化和谷胱甘肽含量作为暴露于电磁场的蟑螂氧化平衡的标志物。我们的结果表明，暴露于电磁场 24、72 小时和 7 天显著增加了从有害热中逃脱的潜伏期。丙二醛（MDA）水平在暴露于电磁场 24 小时后显著增加，并在暴露 7 天内保持升高。暴露于电磁场 7 天的蟑螂中谷胱甘肽水平显著下降。这些结果表明，电磁场暴露是一个相当大的应激因素，它会影响美洲蟑螂的氧化状态和对热的感知。
