摘要: 着重分析植物多样性影响害虫发生为害及种群数量的生态学机制,综合评述了关于这种机制的两种主要假说,即天敌假说和资源集中假说。同时总结了植物多样性增大和减少对害虫控制的有利和不利因素。研究表明农田生态系统中植物多样性的增大在多数情况下能导致某些害虫种群数量的下降,但是目前很难就不同栖境中所有类型的害虫形成一般性的结论.

Abstract: In this paper, the ecological mechanism about the effect of plant diversity on insect pest development and its population dynamics was analyzed. Natural enemy hypothesis and food source concentration hypothesis, the two main prevailing hypotheses concerning this ecological mechanism, were reviewed, and the advantages and disadvantages of plant diversity for insect pest control were summarized. Empirical data show that increased plant diversity in agroecosystems may, at many cases, reduce the populations of certain insect pests, but at present, it is difficult to draw a general conclusion about the effect of plant diversity on populations for all types of insect pests in different habitats.
