摘要
为研究新疆昌吉市灯下昆虫群落结构及多样性,2018年5至9月份在昌吉市滨湖镇应用智能测报灯诱集昆虫,系统调查分析了灯下昆虫群落的结构组成、个体数量、群落特征参数及其时间动态。共收集到昆虫8847头,隶属7目19个类群,灯下植食性昆虫亚群落中,黑额喙丽金龟累计数量最大,而旋幽夜蛾在各月均为优势类群,灯下捕食/寄生性昆虫亚群落中,草蛉类累计数量最大,且在各月均为优势类群。6、7月份灯下昆虫群落个体数量、类群数量、多样性指数、丰富度指数较高,均匀度指数较低,8月份灯下昆虫群落多样性指数、均匀度指数、丰富度指数均较高,优势度指数最低,9月份灯下昆虫群落个体数量、类群数量、多样性指数、丰富度指数最低,优势度指数最高。灯下昆虫群落、植食性昆虫亚群落结构特征时间动态变化趋势相似,多样性指数、均匀度指数在6月下旬至7月上旬出现明显下降,优势度指数则明显上升。灯下捕食/寄生性昆虫亚群落结构特征时间动态波动较大。
In order to study the structure and diversity of insect communities under light-trap in Changji City,Xinjiang,the structure,individual number,community characteristic parameters and their temporal dynamics of insect community under light-trap were systematically investigated and analyzed in Binhu Town,Changji City,from May to September in 2018.A total of 8847 insects were collected,belonging to 19 groups of 7 orders.Among the phytophagous insect sub-community under light-trap,the cumulative number of Adoretus nigrifrons was the largest,while Discestra trifolii was the dominant group in each month.Among the predatory and parasitic insect sub-community under light-trap,the cumulative number of lacewings was the largest,and it was the dominant group in each month.In June and July,the numbers of individuals and groups,diversity index and richness index of insect community under light-trap were higher and the evenness index was lower.In August,the diversity index,evenness index and richness index of insect community under light-trap were higher,and the dominance index was the lowest.In September,the numbers of individuals and groups,diversity index,richness index of insect community under light-trap were the lowest and the dominance index was the highest.The temporal dynamic change trends of the structure characteristics of insect community under light-trap was similar to those of phytophagous insect sub-community.The diversity index and evenness index decreased obviously from late June to early July,while the dominance index increased obviously.The temporal dynamics of structure characteristics of predatory and parasitic insects’sub-community under light-trap fluctuated greatly.
