茶园蜘蛛与广翅蜡蝉的时间和空间关系

  目的  探讨蜘蛛类天敌与广翅蜡蝉科Ricanidae的时间和空间关系，为利用和保护自然天敌提供科学依据。  方法  应用地统计学方法、灰色系统分析方法和生态位分析法对‘安吉白茶’‘Anjibaicha’、‘黄山大叶种’‘Huangshandayezhong’、‘龙井43’‘Longjing 43’、‘农抗早’‘Nongkangzao’、‘平阳特早’‘Pingyangtezao’和‘乌牛早’‘Wuniuzao’等6种茶园盛发期的广翅蜡蝉及11种蜘蛛种群动态进行分析，研究11种蜘蛛与广翅蜡蝉时间和空间关系的密切程度。  结果  根据空间关系密切指数之和可知:6种茶园与广翅蜡蝉空间关系密切的前5位蜘蛛依次是鞍型花蟹蛛Xysticus ephippiafus (5.7415)、斜纹猫蛛Oxyopes sertatus (5.6942)、草间小黑蛛Erigonidium graminicolum (5.6886)、八点球腹蛛Theridion octomaculatum (5.6502)和粽管巢蛛Clubiona japonicola (5.5373)；根据时间关系密切指数之和可知:6种茶园与广翅蜡蝉时间关系密切的前5位蜘蛛依次是草间小黑蛛 (5.6026)、三突花蟹蛛Misumenops tricuspidatus (5.4279)、八点球腹蛛 (5.3519)、鳞纹肖蛸Tetragnatha squamata (5.0791)和锥腹肖蛸Tetragnatha maxillosa (5.0686)。  结论  综合分析得出，与广翅蜡蝉时间和空间关系密切的前3位蜘蛛依次是草间小黑蛛 (11.2912)、八点球腹蛛 (11.0021)和三突花蟹蛛 (10.9935)。表10参27

Temporal and spatial relationship between spiders and Ricanidae in tea gardens

  Objective  The objective is to exlore the temporal and spatial relationship between natural enemies of spiders and Ricanidae, so as to provide scientific basis for the use and protection of natural enemies.  Method  Geostatistics, grey system analysis and niche analysis were used to analyze the population dynamics of Ricanidae and 11 spiders during their blooming period in 6 kinds of tea gardens, including ‘Anjibaicha’, ‘Huangshandayezhong’, ‘Longjing 43’, ‘Nongkangzao’, ‘Pingyangtezao’ and ‘Wuniuzao’. The close degree of temporal and spatial relationship between 11 species of spiders and Ricanidaein was studied.  Result  According to the sum of spatial closeness indices of the 6 tea plantations, the top 5 spiders closely related to the space of Ricanidae were Xysticus ephippiafus (5.7415), Oxyopes sertatus (5.6942), Erigonidium graminicolum (5.6986), Theridion octomaculatum (5.6502) and Clubiona japonicola (5.5373) in descending order. According to the sum of time relationship index, the top 5 spiders closely related to the time of Ricanidae were E. graminicolum (5.6026), Misumenops tricuspidatus (5.4279), Theridion octomaculatum (5.3519), Tetragnatha squamata (5.0791) and Tetragnatha maxillosa (5.0686).   Conclusion  According to the comprehensive analysis, the top 3 spiders closely related to the time and space of Ricanidae from large to small are E. graminicolum (11.2912), Theridion octomaculatum (11.0021) and M. tricuspidatus (10.9935).
