江西赣州地区花生田昆虫群落结构及多样性研究

Structure and Diversity of Insect Community in Peanut Fields in Ganzhou

为阐明江西赣州花生田昆虫群落结构及多样性,2014年5~12月利用马来氏网收集法对该地区花生田昆虫进行了调查。结果表明:赣州市花生田共获得昆虫样本55243头,分属于15目、135科。双翅目、半翅目和膜翅目为优势类群,其中蝇科、潜蝇科(双翅目)、茧蜂科、姬蜂科(膜翅目)、叶蝉科(半翅目),为科级优势类群。多样性分析的结果显示,赣州地区花生田的昆虫群落结构丰富度、多样性指数、均匀度指数都较高,三者呈一致趋势,说明赣州花生田昆虫群落具有较高稳定性。

In order to clarify the structure and diversity of insect communities in peanut fields in Ganzhou, Jiangxi Province, we investigated the insect community structure in peanut fields by using malaise trapping from May 2014 to December 2014.The results showed that a total of 55243 insects in 15 orders and 135 families were collected throughout the year.The main orders were Hymenoptera, Diptera, Hemiptera, Coleoptera and Lepidoptera, and the dominant families in each order were Aphididae (Hymenoptera), Muscidae (Diptera), Aphididae (Hemiptera), Coleoptera (Coleoptera), and Coleoptera (Lepidoptera).The results of diversity analysis showed that the diversity, evenness, and richness indices were consistently high in peanut fields.These results indicate that the insect community structure in Ganzhou peanut fields has high stability.
