合肥不同茶园广翅蜡蝉与蜘蛛空间、数量和时间关系

Spatial,quantitative and temporal relationships between ricanidae and spiders in different tea plantations in Hefei

文章运用地学统计学方法、灰色关联度分析法及生态位分析方法,研究合肥地区黄山大叶种茶园、龙井43茶园、农抗早茶园和平阳特早茶园中与广翅蜡蝉数量、时间和空间维度上关系密切的天敌种类。根据密切指数之和得出,与广翅蜡蝉(Ricanidae)在数量、时间和空间维度上关系密切的前4位天敌,黄山大叶种茶园依次是鞍型花蟹蛛(Xysticus ephippiafus)、三突花蟹蛛(Misumenops tricuspidatus)、锥腹肖蛸(Tetragnatha maxillosa)及八点球腹蛛(Theridion octomaculatum);龙井43茶园依次是鞍型花蟹蛛(Xysticus ephippiafus)、草间小黑蛛(Erigonidium graminicolum)、三突花蟹蛛及黑色跳蛛(Plexippus paykulli);农抗早茶园依次是八点球腹蛛(Theridion octomaculatum)、三突花蟹蛛、草间小黑蛛及粽管巢蛛(Clubiona japonicola);平阳特早茶园依次是草间小黑蛛、锥腹肖蛸、三突花蟹蛛以及八点球腹蛛。根据密切指数之和、位次序号总和及在前4位天敌中出现次数综合分析得出,与广翅蜡蝉在数量、时间和空间维度上关系密切的前4位天敌依次是三突花蟹蛛、草间小黑蛛、八点球腹蛛及鞍型花蟹蛛。研究结果可为广翅蜡蝉生物防治提供参考。

To explore the natural enemy species of ricanidae that are closely related in number,time and spatial dimensions,and to provide a reference for biological control of ricanidae.Geostatistics,grey system analysis and niche analysis were used to that the natural enemy species closely related to ricanidae in number,time and spatial dimensions in Huangshandayezhong,Longjing 43,Nongkangzao and Pingyangtezao tea plantations in the Hefei area was studied.The top four natural enemies that were closely related to the Ricanidae in quantitative,temporal and spatial dimensions,as derived from the sum of closeness indices. In the Huangshandayezhong tea plantation were theXysticus ephippiafus, Misumenops tricuspidatus, Tetragnatha maxillosa and Theridion octomaculatumin descending order. In the Longjing 43 tea plantation were the Xysticus ephippiafus, Erigonidiumgraminicolum, Misumenops tricuspidatus and Plexippus paykulli in descending order. In the Nongkangzao tea plantation were the Theridion octomaculatum, Misumenops tricuspidatus, Erigonidiumgraminicolum and Clubiona japonicola in descending order. In the Pingyangtezao tea plantation werethe Erigonidium graminicolum, Tetragnatha maxillosa, Misumenops tricuspidatus and Theridionoctomaculatum in descending order. Based on the sum of the closeness index, the sum of the rankorder numbers and the number of occurrences among the top four natural enemies, the top four naturalenemies that were closely related to the ricanidae in numerical, temporal and spatial dimensions werethe Misumenops tricuspidatus, Erigonidium graminicolum, Theridion octomaculatum and Xysticusephippiafus in descending order. The results could provide a reference for the conservation andutilization of natural enemies in the biological control of the ricanidae.
