摘　　要：水椰八角铁甲Octodonta nipae(Maulik)是一种危险性林业检疫性害虫,主要危害棕榈科植物,对棕榈科植物的苗木繁育、生态环境和城市绿化等均具有严重危害。自2001年入侵我国以来,先后对水椰八角铁甲的入侵特性、生物生态学特性、免疫响应及其机制等进行系统研究,并取得了一定的研究成果:水椰八角铁甲具有较高的种群遗传多样性,最适的温度范围为26~29℃,对极端温度的耐受能力不强,但其耐寒性具有一定的可塑性;金山葵、加拿利海枣和银海枣是其比较喜爱的棕榈科寄主植物,多次交配是水椰八角铁甲常见的繁殖策略,当水椰八角铁甲入侵后面临不良因素时,其细胞和体液免疫可积极响应,因此,水椰八角铁甲具有较强的适应能力和繁殖能力,能够入侵我国长江以南大部分地区。本文主要总结了这些工作的研究进展。Octodonta nipae(Maulik),a dangerous quarantine pest for forestry,mainly attacks palm plants,which has caused serious damage to nursery stock for palm plants,ecological environment,and city afforestation.Since this invasive pest was first discovered in 2001 in China,numerous works have been done in the fields of invasive characteristics,biological and ecological characteristics,immune response and the underlying mechanisms,and some results have been achieved.O.nipae has a high population genetic diversity.It develops and grows optimally at the temperature range of 26~29℃.It shows no tolerance to extreme temperatures but to some extent owing a plasticity in cold resistance.Syagrus romanzoffiana(Cham.)Glassman,Phoenix canariensis Hort.ex Chabaud and P.sylvestris Roxb.are its favorite host plants.O.nipae usually adopts multiple mating strategy for reproduction;when encountering an improper environment,O.nipae responds quickly with activating cellular and humoral immunity.Therefore,O.nipae has characteristics of strong adaptability and reproductive ability,which can help them toinvade most south areas of the Yangtze River in China.In this review,we summarized these related progress in China based on published thesis and papers.
