摘　　要：为了有效监控永兴岛岛礁植物害虫发生与危害,系统开展8种危险性害虫在永兴岛的空间生态位与分布格局调查研究,首次发现木瓜秀粉蚧、扶桑绵粉蚧、椰心叶甲、榕蓟马、透翅天蛾与拟三色星灯蛾、蔷薇三节叶蜂、美洲斑潜蝇在永兴岛的空间生态位与分布格局存在显著差异。木瓜秀粉蚧、扶桑绵粉蚧、椰心叶甲、榕蓟马、透翅天蛾在永兴岛的东部、南部、西部、北部、中部均为聚集分布,聚集度指标均表现为I> 0、m^(*)/m>1、C> 1、K> 0和CA> 0;而拟三色星灯蛾、蔷薇三节叶蜂、美洲斑潜蝇在永兴岛的东部、南部、西部、北部、中部则均为均匀分布,聚集度指标均表现为I <0、m^(*)/m <1、C <1、K <0和CA <0。8种害虫在永兴岛的分布型均通过m^(*)-m回归法验证。结果表明,木瓜秀粉蚧、扶桑绵粉蚧、椰心叶甲、榕蓟马、透翅天蛾较三色星灯蛾、蔷薇三节叶蜂、美洲斑潜蝇聚集突发成灾概率大。To monitor the occurrence and damage of plant pests in Yongxing island,the spatial niche and distribution patterns of eight dangerous pests in Yongxing island were systematically investigated.It was found for the first time that the spatial niche and distribution patterns of Paracoccus marginatus,Phenacoccus solenopsis,Brontispa longissima,Gynaikothrips fi-corum,Cephonodes sp.,Utetheisa lotrix,Arge geei,and Liriomyza sativae were significantly different in Yongxing island.The spatial distributions of P.marginatus,P.solenopsis,B.longissima,G.ficorum,and Cephonodes sp.were aggregated.Their aggregation indexes of east,south,west,north,and central of Yongxing island were I>0,m^(*)/m>1,C>1,K>0,and CA>0,while the spatial niche and distribution patterns of U.lotrix,A.geei and L.sativae were well-distributed and their aggregation indexes of east,south,west,north,central of Yongxing island were I<0,m^(*)/m<1,C<1,K<0,and CA<0,respectively.The distribution patterns of the above eight pests in Yongxing Island were verified by the m^(*)-m regression method.The results above indicated that compared to U.lotrix,A.geei,and L.sativae,there might be a higher probability of sudden disas-ter of P.marginatus,P.solenopsis,B.longissima,G.ficorum,and Cephonodes sp.
