()
Abstract:
Different attenunant multiples of KKY were used to investigate the disturbance on the characteristic parameters of arthropod community at plum orchards. The result shows that KKY has effectual inhibition on arthropod community, and the execution in spider arthropod sub-community is small.Therefore,it is a suitable pesticide from plant.
