三种控制因子对湿地松粉蚧联合控制作用的模拟分析

Control Effect of Predator Nephus ryuguus Combined with Entomogenous Fungi Cladosporium cladosporioides and Verticillium lecanii against Oracella atuta

利用虫生真菌蜡蚧轮枝菌、芽枝状枝孢霉和圆斑弯叶毛瓢虫对湿地松粉蚧的自然种群进行控制试验,在湿地松粉蚧自然种群连续生命表的基础上,通过以空间状态方程为分析手段,就圆斑弯叶毛瓢虫、芽枝状枝孢霉和蜡蚧轮枝菌对湿地松粉蚧联合作用进行了模拟分析,结果表明各种组合比较单独因子更能有效地控制湿地松粉蚧。

The entomogenous fungi had a good control effect on the population of Oracella atuta(Lob-dell). On the base of the life table of the O.atuta,analyzed the result of Nephus ryuguus,Cladosporium cladosporioides(Fres.) and Verticillium lecanii on the O.atuta.The result indicated that using more than two kinds step had more effect than using one kind step.
