Abstract: Objective To compare on the biological diversity of mosquitoes at different altitude Mengshan mountains.Methods Apply human-bait net trap,human-bait landing catches,cow-bait landing catches,human-bait net catches and whipping net methods to obtain adult mosquitoes,and the larvae was counted gaining by 50-500 ml spoons,and record the environmental.The indexes of abundane and diversity(SAD),ralative rate species(RR),relative extreme amount species(RA),community uniformiry(CU),biomass and probability of inter-specific encounter(PIE),the Dmax and species density(SD) were investigated and compared.The similarity indice between different connunities were derived statistically.Results Total 2 013 mosquitoes were collected,of which 1 724 were at 200-300 m,accounting for 85.6%,257 at 700-800 m,accounting for 12.8%,and only 32 at 1 156 m,the top of the mountains.The seven index are 13,16.67,76.92,0.272,0.310,0.71,1 724 at 200-300 m;12,58.33,16.67,0.443,0.417,0.69,157 at 700-800 m,and 9,22.22,0.00,0.845,0.750,0.25,32 at 1 156 m.The RA was more at 200-300 m,and the RR was more at 700-800 m.Conclusion The biological diversity of community structures of mosquioes depend on their habitat,the SAD and SD of mosquito communities in higher altitude are lower than those in lower altitude,but the CU and PIE are hight.When the RA is higher,the PIE is lower,then the D. is higher also.
摘要: 目的 对蒙山不同海拔高度处的蚊虫群落进行多样性的比较研究。方法 使用人帐诱捕法、动物诱捕法、挥网法等采集成蚊,用勺捞取蚊幼虫带回实验室待羽化后鉴定蚊种并计数。运用丰富度、相对稀有种类数(%)、相对极低种类数(%)、种间相遇概率(PIE)、均匀度、最优势种、种群密度等7个指标对采集的蚊虫进行数据处理,并对蒙山不同海拔高度的蚊虫进行多样性的比较研究。结果 调查中共捕获成蚊及由幼虫孵化来的成虫计2 013只,其中在海拔200~300 m处捕获1 724只,占85.6%;700~800 m处257只,占12.8%,而在1 156 m的山顶处仅32只,占1.6%。7个多样性指标在200~300 m处分别是13、16.67、76.92、0.272、0.310、0.71和1 724;在700~800 m处分别是12、58.33、16.67、0.443、0.417、0.69和157;在1 156 m处分别是9、22.22、0.00、0.845、0.750、0.25和32。在200~300 m处的相对极低种类数较多,700~800 m处的相对稀有种类数较多,两者在1 156 m处均不明显。结论 不同海拔高度处蚊虫群落的多样性有明显的不同,越是接近蒙山底部,蚊虫的丰富度、种群密度增大,种间相遇概率和均匀度因有优势蚊种的存在而逐渐降低。当相对极低种类数值越高时,种间相遇概率越低,最大优势种的指数值则越高。
