1High-nickel insects and nickel hyperaccumulator plants: A review显示文摘昆虫能在整个身体的元素的集中极大地变化。与 Ni 亢奋的蓄电池植物联系的昆虫的最近的调查与相对提高的整个身体的 Ni 层次识别了昆虫。可得到的有限数据的评估显示 500 μg Ni/g 的整个身体的 Ni 集中是非凡的:我建议有一个平均数的昆虫种 500 μg Ni/g 珍视或更大在幼虫 /nymph 或成年的阶段,被认为“一只 high-Ni 昆虫”。用 500 μg Ni/g 标准, high-Ni 昆虫的 15 种类在 Mpumalanga (南非) 从研究被识别了到日期,新喀里多尼亚和加利福尼亚(美国) 。Ni 集中报导了的最高的平均数是为南非的 Stenoscepa 种的美女的 3 500 μg Ni/g (直翅目:Pyrgomorphidae ) 。high-Ni 昆虫(66%) 的多数是 heteropteran 草食动物。high-Ni 昆虫主人偏爱的研究显示他们是 monophagous (或将近这样) 在特别 Ni 亢奋的蓄电池植物种上。许多在这些昆虫的身体的 Ni 在他们的勇气(多达 66%75%) ,但是提高的层次也被发现了在肾小体小管,为处理一本 high-Ni 食谱作为一策略建议有效消除。Ni 的织物层次通常比内脏集中低得多,但是多达 1200 μg Ni/g 从脱下的皮被报导了,建议 molting 可以是 Ni 消除的另一条小径。这些昆虫的高 Ni 集中的一生态的功能可以是对生来的敌人保卫他们,但是标明日期仅仅一试验性的测试支持了“这元素的防卫”假设。社区级的研究显示 high-Ni 昆虫动员 Ni 进食物网,但是 Ni 的简历累积不发生在植物草食动物或草食动物食肉动物步。Unsurprisingly, Ni 简历累积索引为与另外的昆虫种类相比的 high-Ni 昆虫是更大的在 Ni 亢奋的蓄电池植物上喂。有进由 Ni 亢奋的蓄电池植物,而是没有 high-Ni 昆虫的花的昆虫来宾的食物网的 Ni 动员的一些证据花的来宾被报导了。Robert S.

3Stress response of Lymantria dispar asiatica(Lepidoptera:Erebidae)larvae and its gut microbiota to manganese ion显示文摘To study the effect of manganese exposure on the herbivorous insect Lymantria dispar asiatica,fourthinstar larvae were fed a MnCl_(2)-amended diet(LdMn)for 84 h(0.40 mmol MnCl_(2)/g diet).Larvae were weighed before and after the diet administration to assess larval gain in mass under manganese exposure.The whole bodies of half of the survivors were ground in liquid nitrogen for measuring enzyme activities and total antioxidant capacity(T-AOC).The intestinal tracts of the remaining survivors were collected and immediately frozen in liquid nitrogen for 16S rDNA sequencing of gut microbiota.Larvae under manganese stress lost significant mass(p<0.05).The activities of digestive and antioxidant enzymes and T-AOC,but not trehalase and polyphenol oxidase,were significantly higher after Mn exposure,(p<0.05).A Venn diagram illustrated that the gut microbial OTU composition in the larvae also changed.Community pies and correlation heatmaps also showed different relative abundances of gut microbes.In other words,species quantity and relative abundance of gut microbes agreed with PCoA visualization and indicated that the gut microbial community in L.dispar asiatica larvae differed significantly between control and LdMn.Functional classification also suggested that exposure to manganese stress significantly decreased gut microbial coenzyme transport and metabolism in L.dispar asiatica larvae.These results further our understanding about stress response of L.dispar asiatica larvae.Jianyong Zeng Jiaxing Guo Jianghong Shi Zhongbin Shi Guocai Zhang Jie Zhang 2021Journal of Forestry Research2021,32,3:0
