摘要
摇蚊幼虫广泛分布于各种类型的水体底部或水生植物间。由于种类多,且多数种类的个体数量大而成为淡水水体中主要的一类动物。摇蚊幼虫是重要的水生生物资源,对维持和促进渔业发展,关系重大。又因其区系组成与环境性能有密切关系,其群落组成和变化能反映环境质量的变动情况,已被广泛应用于监测和评价水质。世界各国,特别是欧美和日本,对摇蚊科昆虫的研究十分重视。我国该领域的研究起步较晚,截止1986年年底,仅报道176种m。
Larvae of Chironomids are important aquatic animals in both lentic and lotic freshwaters. Their significance as food of fish has not always been sufficiently emphasised, partly because of problems of identification encountered by scientists and fishermen. Chironomid larvae are also used in environmental protection as monitoring of water quality. Before the end of 1986, the number of Chironomid species reported in China was 176. This paper reports 40 species of larvae belonging to 29 genera of 4 subfamilies which were obtained from rivers, lakes and other waterbodies of Liaoning province in recent years and were new records in China. Information was given on the distribution and ecology of these species.
