摘要: 2006年5-9月,采用枝条套袋取样技术对浙江省舟山市松材线虫病Bursaphelenchus xylophilus疫区内黑松Pinus thunbergii冠层节肢动物群落的组成和结构进行了研究。结果表明:供调查的黑松冠层中,共有节肢动物12目45科95种,共计3 077个个体。其中捕食性昆虫类群有10科17种89头,食叶害虫类群11科16种1 477个,枝梢害虫类群8科18种1 186个,蜘蛛类群11科33种287只,游走性类群5科13种38个。主要害虫种类有浙江黑松叶蜂Nesodiprion zhejiangensis,草履蚧Drosicha corpulenta,松沫蝉 Aphrophora flavipes,松褐天牛 Monochamus alternatus等。各功能集团主要分布在树冠的中下层,除捕食性昆虫外,总群落及其他各类群对方位的选择性较小,捕食性昆虫主要分布在向阳的东部、南部和西部。以食叶害虫和枝梢害虫为主的害虫类群在5月份的优势集中性最高,在7月物种丰富度最高,6-8月危害最为严重。而蜘蛛类和捕食性昆虫等捕食性类群在调查的各个月份中的优势集中性均比较稳定,仅在8月有所降低。图3表1参23Abstract: From May to September 2006,the composition and structure of canopy arthropods in Pinus thunbergii were studied in Zhoushan City,Zhejiang Province using the branch bagging technique. Results in the pooled samples showed a total of 3 077 individuals from 95 species belonging to 45 families and 12 orders composed of predaceous insects:89 individuals from 17 species in 10 families,leaf-eating insects:1 477 individuals from 16 species in 11 families,branch and top-eating insects:1 186 individuals from 18 species in 8 families,spiders:287 individuals from 33 species in 11 families,and tourists:38 individuals from 13 species in 5 families. The main species included Nesodiprion zhejiangensis,Drosicha corpulenta,Aphrophora flavipes,and Monochamus alternatus. All functional groups were mostly distributed in the mid and lower layers of the canopy. Except for predaceous insects that preferred staying in the sunny parts of the canopy (the east,south,and west sides),all other groups were not selective as to orientation. The predominance of pests,including the leaf-eating group and the branch and top-eating groups,was highest in May with species richness highest in July. The greatest damage occurred between June and August with the predaceous group,including insects and spiders,dominant in every month.[Ch,3 fig. 1 tab. 23 ref.]
