哀牢山西坡地表蚂蚁资源调查

The investigation of ground ants resources on the west slope of mountain ailao

采用样地调查法调查了哀牢山西坡4个地段28块样地140个样方地表蚂蚁资源。调查结果为:采集地表蚂蚁标本共3592号,分属110种37属7亚科,且蚂蚁密度高达25.7头/m2;优势类群优势明显,其中切叶蚁亚科地表蚂蚁种类最多,占总物种数的47.3%;广布种为黄足厚结猛蚁、爪哇厚结猛蚁和菱结大头蚁;特有种较多,单种属有16属,仅在1个样地中出现的蚂蚁有61种,在2个样地中分布的蚂蚁有33种;部分蚁类个体数量极少,个体数低于10头的蚂蚁有70种,其中31种蚂蚁只有1头个体。

This paper dealed with the ground ants of Mt.Ailao,based on investigation method of sample plot.Numerically,140 sample plots in 28 sample stands at 4 different sections on west slope were investigated.The results were as follows：（1） the total number of ground ants specimen was 3 592 individuals which belongs to 110 species,37 genera and 7 subfamilies.Density of ground species was up to 25.7 inviduals/m2;（2）The richness of dominant species was high because 47.3% of total species number was the ground ants belonging to Myrmicinae take up;（3） Widespread species were Pachycondyla luteipes,P.javana,P.rhombinoda all belonging to pachycondyla genus;（4）The number of endemic species were rich because there were 16 species belonging to monotypic genera,61 species occurred only in one of 28 sample plots,and 33 species occurred in two of 28 sample plots;（5）Quantity of some ants species was low because there were 70 species of ground ants whose number was lower than 10 individuals,and 31 species of which had only an individual.
