“金属离子在包括昆虫在内的生物体中扮演着独特的角色。其中一些，如钠和钾，在渗透调节和“血液和肠道”运输生理中起着核心作用，并与寒冷适应有关。钙作为第二信使和结构元素是一个关键角色。其他金属，特别是那些具有多种氧化还原状态的金属，可以是许多金属酶的辅助因子，但过量会对生物体造成毒性氧化应激。这篇简短的综述选择了一些经典知识被最新进展补充的例子，以强调金属作为昆虫生存所必需的营养物质的重要性。
'Metal ions play distinct roles in living organisms, including insects. Some, like sodium and potassium, are central players in osmoregulation and 'blood and guts' transport physiology, and have been implicated in cold adaptation. Calcium is a key player as a second messenger, and as a structural element. Other metals, particularly those with multiple redox states, can be cofactors in many metalloenzymes, but can contribute to toxic oxidative stress on the organism in excess. This short review selects some examples where classical knowledge has been supplemented with recent advances, in order to emphasize the importance of metals as essential nutrients for insect survival.
