| 摘 要： | 根据对白三叶草草坪地的系统调查,研究了中黑盲蝽(Adelphocoris saturalis Jakovlev)及其天敌种群动态,并用相关系数分析法寻找控制中黑盲蝽数量变动的关键天敌因素。结果表明:中黑盲蝽(Adelphocoris saturalis Jakovlev)、蜘蛛(spider)、龟纹瓢虫Pyopylaea japonica(Thun-berg)]、丽草蛉(Chrysopa formosa Brauer)在白三叶草草坪地均为聚集分布;控制中黑盲蝽数量的主要天敌是蜘蛛,其相关系数为0.9269。

| Abstract: | Based on the data obtained from the triforlium lawn,the population dynamics of Adelphocoris saturalis Jakovlev and its natural enemies were studied.In order to find the key factors which effected the population of Adelphocoris saturalis Jakovlev,the regression analysis was used.The result showed that Adelphocoris saturalis Jakovlev,spider,Propylaea japonica(Thunberg)and Chrysopa formosa Brauer all distributed spatially in the triforlium lawn.The correlation coefficient of the three natural enemies are 0.9269,while the spider is the most import-ant factor which effected the population dynamics of Adelphocoris saturalis Jakovlev. |
