云南省华宁县3种柑橘幼园昆虫多样性研究

Diversity of Insects in Citrus Orchards in Huaning County,Yunnan Province

于2010年8月-2011年4月使用陷阱法调查了云南省华宁县盘溪镇荒地改造型柑橘园(Ⅰ)、农田改造型柑橘园(Ⅱ)和传统型柑橘园(Ⅲ)的昆虫群落多样性。样地Ⅰ中采集标本212号,在样地Ⅱ中采集标本313号,在样地Ⅲ中采集标本431号。鞘翅目(Coleoptera)、双翅目(Dipter-a)、膜翅目(Hymenoptera)蚁科(Formicidae)为优势类群,占59.5%。3种类型柑橘幼园中蚂蚁常见种及蚂蚁物种组成有差异;样地Ⅲ的昆虫多度及物种丰富度S值最高,样地Ⅰ昆虫多度最低,样地Ⅱ昆虫物种丰富度S值最低;3种类型柑橘幼园昆虫群落结构不相似;3种类型橘园蚂蚁指示物种也不同。研究表明,前期土地利用方式的差异以及周边生境影响了柑橘幼园内昆虫群落物种组成、多样性、群落结构及指示物种。

To reveal the effects of different land use types in early stage on insects community diversity in the Citrus orchard,an investigation of insect community diversity in 3 plots（the Citrus orchard remade from wastelandⅠ,the Citrus orchard remade from farmland Ⅱ and the traditional Citrus orchard Ⅲ）,was carried out by pitfall trapping in Panxi Township,Huaning County,Yunnan Province of China.There were 212 insect individuals collected from the plot Ⅰ,313 insect individuals collected from the plot Ⅱ and 431 insect individuals collected from the plot Ⅲ.The dominant groups were Coleoptera,Diptera and Formicidae（Hymenoptera）,which accounted for 59.5%.There were differences in common species and composition of ants in the three types Citrus orchards.The plot with the highest insect abundance and species richness was plot Ⅲ,the plot Ⅰ had the lowest insect abundance,and the plot Ⅱ has the lowest species richness.There were lower similarity of insect community in the three types Citrus orchards.The indicator species of ants were different in the three types Citrus orchards.The results showed that the insect composition,diversity,community and indicator species in Citrus orchards were affected by the land use types in early stage and the habitats surrounding the Citrus orchard.
