The most severe outcome of the widespread interspecific competition that occurs between invasive organisms and their local congeners is species displacement. The western flower thrips, Frankliniella occidentalis (Pergande), which originated from western North America, has invaded much of the agricultural world since the 1970s, and in so doing, has become a dominant thrips species in many of the areas it has invaded. Its invasion success and the extent of its distribution in the regions it has invaded can be largely attributed to its superiority in interspecific competition. In some instances, however, F. occidentalis has been less successful in its invasion attempts and has not become dominant in its new environment. Thrips species displacements often arise from interactions of different mechanisms that are mediated by numerous biotic and abiotic factors. In this review, we summarize competitive interaction events that have been documented between F. occidentalis and several species of other locally present thrips, their interaction mechanisms and mediating factors. This review will help to better understand displacement events of thrips species in some areas and to develop management strategies for thrips species with high invasion potential.

入侵生物与其本地同源物种之间发生的广泛种间竞争的最严重后果是物种流离失所。西方花蓟马Frankliniella occidentalis（Pergande）起源于北美西部，自1970年代以来已入侵了许多农业世界，因此，已成为它入侵的许多地区的主要蓟马种类。它的入侵成功及其在其入侵地区的分布范围很大程度上可以归因于其在种间竞争中的优势。然而，在某些情况下，西洋参在入侵尝试方面不太成功，在新环境中也未占主导地位。蓟马种类的移位通常是由许多生物和非生物因素介导的不同机制的相互作用引起的。在这篇综述中，我们总结了西洋参和其他几种当地蓟马的竞争相互作用事件，它们的相互作用机制和中介因子。这篇综述将有助于更好地了解某些地区蓟马种类的迁移事件，并为具有高入侵潜力的蓟马种类制定管理策略。
