摘　　要：调查了无量山4个垂直带21个样地7种植被类型的猎蝽群落多样性,共采集猎蝽标本168号,分属于7亚科22属32种,其中种类最多的真猎蝽亚科有13属20种,丽勺猎蝽和彩纹猎蝽数量最多、分布最广;有4亚科为单属单种,另有8种猎蝽仅在1个样地中出现,7种猎蝽只发现1头个体。整体上无量山猎蝽各项群落指标南段与北段、东坡与西坡的差异不大,属中等相似水平;不同植被类型中却表现为云南松林、针阔叶混交林、季风常绿阔叶林和思茅松林的群落多样性明显优于其他植被类型;不同海拔高度上的群落指标也表现为2 000 m和1 750 m群落多样性优于其他海拔高度,具有明显的垂直地带性规律。The composition of assassin bug communities and species diversity of 4 vertical zones 21 sample plots 7 vegetation types in Wuliang mountain were studied.168 Reduviidae specimens were collected,which belonged to 32 species,22 genera and 7subfamilies.The first dominant subfamily was Harpactorinae,which included 13 genera 20 species.The largest number species and the most widespread species were Cosmolestes pulcher and Euagoras plagiatus.There were 4 subfamilies,which possessed only 1 genus and 1 species each subfamily.There were 8 species distributed only 1 plot,and the individual number of 7 assassin bug species was only 1.As a whole,the average assassin bug community indexes of all plots between southern region and northern region,east slope and west slope in Wuliang mountain were medium similar level.But in the different vegetation types,the average assassin bug community indexes of all plots of pinus yunnanensis forest,theropencedrymion,monsoon evergreen broad-leaved forest and pinus kesiya were superior to that of other vegetation types.On different altitudes,the average assassin bug community indexes of all plots on 2 000 m and 1 750 m were better than that on the other altitudes,and all community indexes showed obviously the vertical regional regularity.
