摘要
对吉林省西部地区蜻蜓目(Odonata)昆虫资源进行了连续调查。调查发现,吉林省西部地区蜻蜓目昆虫共有47种,隶属于9科28属。其中,差翅亚目(Anisoptera)的各级别水平明显高于束翅亚目(Zygoptera);属数和物种数最多的是蜻科(Libellulidae);春蜓科(Gomphidae)、蜻科、蟌科(Coenagrionidae)和丝蟌科(Lestidae)是该地区的优势类群。吉林省西部地区蜻蜓目昆虫成虫群落的演变随着季节的变化而变化。5月份,蜻蜓种群数量缓慢抬升,6至7月份,种群数量显著增加,8至9月份,物种数和个体数量都呈现出下降趋势;不同月份优势种不同。
A successive investigation on the resource of Odonata was conducted in western Jilin. There are 47 species of Odonata in the western region of Jilin,belonging to 9 families and 28 genera. Among them,the levels in the Anisoptera are significantly higher than those in the Zygoptera,the genus number and species number are maximum in Libellulidae,and Gomphidae,Libellulidae,Coenagrionidae and Silk Coenagrionidae are the dominant groups in the region. The evolution of Odonata adult communities in the western region of Jilin changes with the seasons. In May,the number of dragonfly communities increases slowly,significantly from June to July,and both the number of species and the number of individuals show a declining trend from August to September,and the dominant species is different in May to September.
