贵州雷公山国家级自然保护区金龟总科昆虫多样性初步调查

为了解贵州雷公山国家级自然保护区的金龟总科Scarabaeoidea昆虫资源状况,2011—2018年对保护区内的金龟总科昆虫开展了多次调查。共采获标本160号,隶属于9科38属63种,其中贵州省新记录4种。α多样性分析结果表明,落叶阔叶林中金龟总科昆虫的多样性和丰富度指数最高(0.365和6.897),但均匀度指数最低(0.107),亚热带针叶林最低(0.260和2.337),但均匀度指数最高(0.125),其他生境类型差异不明显。金龟总科昆虫多样性、丰富度指数在5月最高(0.359和7.313),6月次之(0.347和7.048),其余月份较低;在均匀度上,3月最高(0.198),其次为9月(0.147),其余月份相差不大。金龟总科昆虫多样性和均匀度指数在1500~1700 m最高(0.341和0.129),多样性和丰富度指数在1700 m以上最低(分别为0.123和1.116),均匀度指数在1300~1500 m最低(0.080),但丰富度指数最高(8.252),其余指数的差异不明显。群落相似性分析结果表明,马尾松阔叶混交林与落叶阔叶和常绿阔叶混交林之间相似性最高(0.429),其次是落叶阔叶林、落叶阔叶和常绿阔叶混交林(0.415)。

Primary Survey on Diversity of Scarabaeoidea Insects in the Leigong Mountain National Nature Reserve,Guizhou

From 2011 to 2018,multiple collecting trips for surveys on the Scarabaeoidea insects were carried out in the Leigong Mountain National Nature Reserve(Guizhou Province).A total of 160 specimens belonging to 63 species under 38 genera of 9 families were collected and identified.Among them,4 species are the new records of Guizhou Province.The results ofαdiversity analysis showed that the diversity and richness indices for Scarabaeoidea insects in the deciduous broadleaf forest are the highest(0.365 and 6.897,respectively),while evenness index for Scarabaeoidea insects is the lowest(0.107).The diversity and richness indices for Scarabaeoidea insects in the subtropical coniferous forest are the lowest(0.260 and 2.337,respectively),while the evenness index for Scarabaeoidea insects is the highest(0.125).Indices for Scarabaeoidea insects in other habitat types are not significantly different.From the aspect of Scarabaeoidea insects collected by month,the diversity and richness indices for Scarabaeoidea insects collected in May are the highest(0.359 and 7.313,respectively),and those of June(0.347 and 7.048,respectively)were higher.These indices for other months are not significantly different.The evenness index for Scarabaeoidea insects collected in March is the highest(0.198),followed by September(0.147).For altitude ranges,the diversity and evenness indices for Scarabaeoidea insects collected from 1500 m to 1700 m are the highest(0.341 and 0.129,respectively),and the lowest diversity and richness indices(0.123 and 1.116,respectively)were detected in the Scarabaeoidea insects collected above 1700 m.The evenness index for Scarabaeoidea insects collected from 1300 m to 1500 m is the lowest(0.080),but the richness index is the highest(8.252).Other indices are not significantly different.The results of community similarity analysis showed that the similarity of Scarabaeoidea insects collected from mixed forests of Masson s pine(Pinus massoniana)and broadleaf trees and mixed forests of evergreen broadleaved and deciduous broadleaved is the highest(0.429),followed by the deciduous broadleaved forest and the mixed forest of deciduous broadleaved and evergreen broadleaved(0.415).
