摘要
目标:为明确太原市汾河景区不同生境蚧虫种类及相关性。2016年—2018年采用样线法、样方法、访谈法对山西省太原市汾河景区蚧虫种类、分布和寄主等做了全面调查。结果显示太原市汾河景区蚧虫共计5科14属14种,其中桑白盾蚧、朝鲜毛球蚧、矢尖蚧为优势种;景区寄主共计3门3纲11目13科19属22种;碧桃受害最多;草本及花卉未发现蚧虫;蚧虫天敌共计2纲6目7科8种;汾河东西两岸的寄主中等相似,蚧虫中等不相似;湿地东西两岸、汾河东岸与湿地东岸均为寄主中等不相似,蚧虫中等相似;湿地公园东西两岸之间、湿地公园与汾河公园之间均无显著差异;汾河东西两岸的蚧虫种类有显著差异。结论:蚧虫种类与寄主、生态环境有关,相对干旱的汾河公园物种相对不丰富,虫口密度大,湿润的湿地环境适宜植被及昆虫生长发育,寄主多,蚧虫种类多,但植被树势优、抗性强、天敌多、生物多样性丰富,所以蚧虫数量少,虫口密度小,有害不成灾。
[Aim]To clarify the species and correlation of scale insects in diff erent habitats of Fenhe scenic spot in Taiyuan City.[Methods]From 2016 to 2019,the species,distribution and hosts of scale insects in Fenhe scenic spot of Taiyuan City,Shanxi Province were investigated comprehensively.[Results]There were 14 species of scale insects belonging to 14 genera and 5 families in Fenhe scenic spot,of which Pseudaulacaspis pentagona,Didesmococcus koreanus and Unaspis yanonensis were dominant species;the host of the scenic spot totaled 13 orders,11 orders,19 genera and 22 species;Amygdalus persica suff ered the most;no scale insects were found in herbs and fl owers;and the scale insects were found on both sides of Fenhe scenic spot.The natural enemies of scale insects are 2 classes,6 orders,7 families and 8 species;There is no signifi cant diff erence between the eastern and Western banks of wetland parks,wetland parks and Fenhe parks,and there are signifi cant diff erences in the species of scale insects between the eastern and Western banks of Fenhe River.[Conclusion]The species of scale insects are related to the host and ecological environment.Compared with the arid Fenhe Park,the species are relatively less abundant,the population density is high,the wet wetland environment is suitable for vegetation and insect growth and development.There are many hosts and kinds of scale insects,but the vegetation is superior,the resistance is strong,the natural enemies are large,and the biodiversity is rich,so the number of scale insects is small,the population density is small,and the harmfulness is not disastrous.
