地磁场（GMF）是一种环境线索，为动物提供方向信息。GMF的强度随空间和时间而变化。转基因食品强度的变化会影响动物的导航及其生理。本文研究了迁飞性昆虫稻飞虱Nilaparvata lugens（N.lugens）和稻褐飞虱（Nilaparvata lugens）的趋光性。通过使用不同强度的磁场研究了细胞铁稳态和铁-硫簇组装所需的线粒体蛋白质褐变蛋白（Nl-fh）。结果表明，N.当在强磁场下的行为竞技场中饲养和测试时，Lugens表现出趋光性降低。除了性能降低之外，强磁场条件的伴随效应是Nl-fh-信使RNA水平降低，并且Nl-fh敲低确实损害了昆虫测试样品中的趋光行为。这导致的结论是，表达的frataxin是依赖于周围磁场的强度和功能frataxin促进趋光行为在N。lugens。
The geomagnetic field (GMF) is an environmental cue that provides directional information for animals. The intensity of GMF is varied over space and time. Variations in the GMF intensity affect the navigation of animals and their physiology. In this study, the phototaxis of the migratory insect rice planthopperNilaparvata lugens(N.lugens) and frataxin inN. lugens(Nl‐fh), which is a mitochondrial protein required for cellular iron homeostasis and iron‐sulfur cluster assembly, were investigated by using different intensities of magnetic field. From the results, individuals ofN. lugensshowed decreased phototaxis when reared and tested in a behavioral arena under a strong magnetic field. Besides the reduction in performance, an accompanying effect of the strong magnetic field condition was a reduced level ofNl‐fh‐messenger RNA, and aNl‐fhknockdown indeed impaired the phototactic behavior in a tested sample of insects. This leads to the conclusion that the expression of frataxin is dependent on the strength of the surrounding magnetic field and that functional frataxin facilitates phototactic behavior inN. lugens.
