为了解辽宁东部地区飞航蜘蛛的群落组成及特点,于2009年5—9月,采用吸虫塔对辽宁岫岩地区的飞航蜘蛛进行了调查。共采集蜘蛛标本549头,隶属于14科。对飞航蜘蛛的群落组成、时间动态、体型大小、发育阶段及性别比例等进行了分析。结果表明:辽宁东部地区飞航蜘蛛多样性丰富,皿蛛科(58.29%)和园蛛科(11.84%)是该地区飞航蜘蛛的优势类群;在成熟蜘蛛个体中,皿蛛科(74.02%)和肖蛸蛛科(11.02%)占有较大比例。蜘蛛飞航行为贯穿于整个调查时期,方差分析表明,8月上旬—9月上旬飞航蜘蛛的个体数量显著高于其他时期。飞航蜘蛛体型均<8mm,体长<3mm的达91.44%。χ2检验显示,飞航的幼蛛个体数量显著高于成蛛;而成蛛中,雄性个体数量显著高于雌性。
In order to understand the community composition and characteristics of flight spiders in eastern Liaoning, a survey was conducted on the flight spiders in Xiuyan, Liaoning from January to September in 2009. A total of 549 spider specimens were collected, belonging to 14 families. The spider community composition, time dynamics, body size, stage of development and sex ratio were analyzed. The results showed that the spiders in the eastern part of Liaoning Province were rich in diversity, and the spiders (58.02%) and the spider spiders (11.84%) were the dominant species in the region. Among the mature spiders, the spiders (74.02% ) And Shaddock (11.02%) accounted for a large proportion. Spider flight throughout the investigation period, analysis of variance showed that in early August - early September flight spiders individuals significantly higher than the number of other periods. Flight spider body size <8mm, body length <3mm of 91.44%. The χ2 test showed that the number of young spiders was significantly higher than that of adult spiders, while the number of male individuals in spiders was significantly higher than that of females.
