用灰色系统分析法和生态位分析法对安徽省潜山县高、中、低3种海拔茶园中2种主要害虫与其天敌在数量和空间上的相互关系进行研讨,经综合排序得出:低海拔茶园假眼小绿叶蝉的主要天敌是锥腹肖蛸、茶色新圆蛛和鞍型花蟹蛛,中海拔茶园为八点球腹蛛、锥腹肖蛸和鞍型花蟹蛛,高海拔茶园为锥腹肖蛸、茶色新圆蛛和草间小黒蛛。低海拔茶园柑橘粉虱的主要天敌是八点球腹蛛、茶色新圆蛛和异色瓢虫,中海拔茶园为鞍型花蟹蛛、八点球腹蛛和茶色新圆蛛,高海拔茶园为锥腹肖蛸、八点球腹蛛和斑管巢蛛。上述几种天敌与2种主要害虫在数量和空间上有显著的追随关系。不同海拔高度茶园中2种主要害虫的主要天敌种类存在差异。
The relationship between quantity and space of two main pests and their natural enemies in high, medium and low altitude tea plantations of Qianshan County in Anhui Province was studied by using gray system analysis and niche analysis. The comprehensive ranking showed that low The main natural enemies of the small green leafhoppers at the tea plantation are Cone-bellied jackals, New-colored brown spiders and Saddle-shaped spider spiders. The mid-elevation tea plantations are eight-point ball spiders, The tea plantation is cone-shaped Shagao, brown new spider and small grasshopper spider. The main natural enemies of citrus whitefly in low altitude tea plantation are eight-point spider spider, new spider spider and heterophorous ladybug, middle-altitude tea plantation saddle spider spider, eight-point spider spider and brown spider spider, For the conical abdomen Xiao, eight-point ball spider and spotted nest spider. The predators and two main pests had significant follow-up in quantity and space. There were differences in the main natural enemies of the two main pests in tea gardens at different altitudes.
