利用扫网,黄盘和巴氏罐诱法对三江平原典型环形湿地周围三个不同类型树林(岛状林,杨树林,松树林)的昆虫进行采集,经初步整理和鉴定,共采集标本24212号,其中昆虫20948号,分属于14目。其他的属于蛛形纲和多足纲。昆虫中种类最多的是双翅目和膜翅目,其次是弹尾目,同翅目,鞘翅目和缨翅目。在高的分类阶元(目)Shannon-wiener指数在松树林最高,杨树林最低。昆虫数量在各个林型中没有明显的不同。在这三个林型里面发现了长翅目蝎蛉,丰富了我国对于蝎蛉分布北限的记录,表明三江平原湿地区是我们昆虫多样性保护的一个重要区域。
The insects of three different types of forests around the typical annular wetland in the Sanjiang Plain were collected by scanning network, yellow disk and pasteurized canopies. After initial sorting and identification, a total of 24212 specimens were collected , Of which insects 20948, belonging to 14 orders. Other belong to the arachnoid and multi-foot program. The most common species of insects are Diptera and Hymenoptera, followed by Phasianidae, Homoptera, Coleoptera and Thysanoptera. The Shannon-wiener index in the highest taxonomic order (highest) was the highest in the pine forest and lowest in the poplar forest. The number of insects is not significantly different in each forest type. In these three forest types found in the Pipistra Scorpio, enriched our northern distribution of scorpionfly records the records, indicating that the Sanjiang Plain wetlands is an important area of insect diversity protection.
