高黎贡山百花岭瓢虫群落结构及物种多样性研究Ⅳ——农耕区不同植被类型瓢虫的物种多样性

Community Structure and Species Diversity of Ladybugs in Baihualing of Gaoligong Mountain

[目的]了解高黎贡山百花岭农耕区不同植被类型瓢虫的物种多样性。[方法]对高黎贡山百花岭农耕区农田、板栗林、核桃林和咖啡林4种植被类型上瓢虫种类及数量进行了调查。[结果]在高黎贡山百花岭农耕区共采集到瓢虫3亚科17属30种1 027头,瓢虫群落多样性从高到低依次为板栗林、农田、核桃林和咖啡林。物种多样性在6～10月间较高但波动大,6和9月多样性最高,冬季最低。咖啡林与板栗林瓢虫群落为中等不相似,农田与核桃林间极相似,其余植被间中等相似。[结论]为高黎贡山百花岭地区瓢虫多样性的保护提供了理论依据。

[Objective] The aim was to understand the species diversity of ladybugs from different types of vegetation in agricultural area in Baihualing of Gaoligong Mountain.[Method] The species and amount of ladybugs from different types of vegetation in agricultural area in Baihualing of Gaoligong Mountain were investigated.[Result] There were 1 027 ladybugs in agricultural area in Baihualing of Gaoligong Mountain,and they belonged to three subfamilies,17 genera and 30 species.The diversity of ladybugs community decreased in the following sequence: Chinese chestnut forest,farmland,walnut forest and coffee forest.There was a higher diversity of ladybug community with big fluctuation form June to October,and the highest diversity of ladybug community appeared in June and September,while it was the lowest in winter.The similarity coefficient between ladybug community of coffee forest and Chinese chestnut forest was moderate dissimilar level;it was very similar between walnut forest and farmland,and it was moderate similar level among other types of forest.[Conclusion] The research provides theoretical basis for the diversity protection of ladybugs in Baihualing of Gaoligong Mountain.
