| 摘 要： | 对秦岭林区针叶树蚜虫区系成分和物种多样性进行了研究.结果表明:秦岭林区以针叶树为寄主的蚜总科昆虫共计2科8属28种.区系成分包括古北种、东洋种、跨两界分布的广布种及特有种4种类型.其中,东洋种所占比例最大,占总数的32.2;古北种和广布种比例次之,各占总数的28.5;特有种占总数的10.8.秦岭不同生境针叶树蚜虫的物种丰富度、多样性指数和均匀度指数有显著差异.

| Abstract: | The species composition and diversity of needle aphids in the Qinling Mountains were studied. 28 species, belonging to 2 families and 8 genera, were recognized, including 9 oriental species (accounting for 32.2 %), 8 northern species (accounting for 28.5%), 8 wide distributing species (accounting for 28.5 %) and 3 endemic species (accounting for 10.8%).The diversity measurement of needle aphids in different habitats showed that degrees of species abundance D MA range from 0.600 2 to 3.301 1, species diversity indexes H from 0.985 to 1.615 and evenness indexes J SW from 0.649 9 to 0.908 9. |
