虽然对荒漠蝗虫和东亚飞蝗等模式蝗虫的特定相变机制已有较好的了解，但在其他非模式蝗虫物种中密度依赖的相多表现性的表达还不是很清楚。本文试图回顾和综合我们对这些非模式蝗虫的认识。根据已有的资料，我发现不同种类的蝗虫有不同的表现形式，并确定了蝗虫物种通常属于大的分类群的模式，其中大多数是非群居的蝗虫物种。虽然蝗虫相多物性在蝗科内已经进化了多次，但我认为应该从系统发育的角度来研究它的进化，因为我在密切相关的物种中发现了类似的依赖密度的表型可塑性。最后，笔者强调了比较分析在理解蝗虫阶段演化中的重要性，并提出了一个基于系统发育的研究框架。
Although the specific mechanisms of locust phase transformation are wellunderstood for model locust species such as the desert locust Schistocerca gregaria and the migratory locust Locusta migratoria, the expressions of density-dependent phase polyphenism in other nonmodel locust species are not wellknown. The present paper is an attempt to review and synthesize what we know about these nonmodel locusts. Based on all available data, I find that locust phase polyphenism is expressed in many different ways in different locust species and identify a pattern that locust species often belong to large taxonomic groups which contain mostly nonswarming grasshopper species. Although locust phase polyphenism has evolved multiple times within Acrididae, I argue that its evolution should be studied from a phylogenetic perspective because I find similar density-dependent phenotypic plasticity among closely related species. Finally, I emphasize the importance of comparative analyses in understanding the evolution of locust phase and propose a phylogeny-based research framework.
