放牧管理可以通过改变植物群落的特征来影响草地昆虫群落的结构和动态。然而，试图更好地了解植物，昆虫和大型食草动物之间的复杂关系仍然受到植物，昆虫和大型食草动物相互作用的影响。在这项研究中，我们测试了一个假设，即大型食草动物对昆虫丰度的影响是食草动物物种特异性和放牧前植物多样性依赖的，使用一个实验，操纵四个放牧处理（即，对照，牛，山羊和绵羊）在低，中，高植物多样性水平在中国东北草甸草原。我们发现，放牧显着增加了整个昆虫群落的丰度。各昆虫目的丰度对放牧处理的反应不同，绵羊放牧下直翅目和同翅目的丰度较高，牛放牧下鞘翅目和双翅目的丰度增加，半翅目的丰度减少，但山羊放牧下鳞翅目的丰度较高。因此，不同的处理深刻地改变了昆虫分类组成。其中以单色真雏蝗Euchorthippus unicolor、红角三角叶蜂Aelia nasuta、红角三角叶蜂Trigonotylus ruficornis、红角叶蜂A.lionidae sp.、（Coccinula quatuordecimpustulata和Cicadellidae sp.）大型食草动物的放牧反应不同，要么增加或减少其丰度。放牧对昆虫丰度的影响是由它们对植被的不同响应机制驱动的。更重要的是，放牧对昆虫丰度在两个命令和物种水平的影响可能取决于植物多样性水平的放牧前。研究结果表明，在不同的植物群落背景下，应使用不同的草食动物物种，以更好地保护管理草地的昆虫群落。
The structure and dynamics of insect community in grasslands can be influenced by grazing management via altered characteristics of plant community. However, attempts to better understand the complex relationships among plants, insects, and large herbivores is still hampered largely by the interactive effects of plants, insects, and large grazers on each other. In this study, we test the hypothesis that the effect of large herbivores on insect abundance is grazer species-specific and pre-grazing plant diversity-dependent using an experiment with manipulating four grazing treatments (i.e., control, cattle, goats, and sheep) at low, intermediate, and high plant diversity levels in a meadow steppe at northeast in China. We show that grazing significantly increased the abundance of the entire insect community. The abundance of each insect order responded differently to grazing treatments, with higher abundance of Orthoptera and Homoptera under sheep grazing, enhanced abundance of Coleoptera and Diptera under cattle grazing, and reduced Hemiptera abundance, but greater abundance of Lepidoptera under goats grazing. Thus different treatments profoundly changed insect taxonomic composition. The six most dominant species (Euchorthippus unicolor,Aelia nasuta,Trigonotylus ruficornis, Curculionidae sp.,Coccinula quatuordecimpustulata, and Cicadellidae sp.) responded differently to grazing by large herbivores, with either increased or decreased its abundance. The effects of grazing on insect abundance were driven by their differential responsive mechanisms for vegetation. More importantly, the effects of grazing on insect abundance at both order- and species-levels potentially depended on plant diversity levels of pre-grazing. Our results suggest that different herbivore species should be used in the background of different plant communities for better conservation of insect community in managed grassland.
