全球气候变化和外来生物入侵是威胁全球生物多样性的重要因素。气候变化如何影响外来植物入侵目前已成为生态学研究的一个热点问题。现有的研究局限于气候变化对入侵植物本身的影响;而气候变化如何影响天敌昆虫等多级营养关系,从而间接影响植物入侵,目前尚无报道。空心莲子草是我国首批公布的入侵物种之一。我国于1986年引进专一性生防天敌莲草直胸跳甲控制该草。但该虫目前仅成功控制了南方水生生境中空心莲子草,而对陆生生境中空心莲子草防效甚微。前期研究表明,陆生生境中空
Global climate change and invasive alien species are important threats to global biodiversity. How climate change affects exotic plant invasion has now become a hot issue in ecology. The existing research limited to the impact of climate change on invasive plants itself; and how climate change affects natural enemies and other multi-level nutritional relationships, which indirectly affect plant invasion, has not been reported. Alternanthera philoxeroides is one of the first published invasive species in China. China in 1986 to introduce a special natural enemy of natural enemies of larvae straight chest control of the grass. However, at present, the pest has successfully controlled the alligator weed in the southern aquatic habitat and has little control effect on the native lotus seed in the terrestrial habitat. Preliminary studies have shown that terrestrial habitats hollow
