Abstract

The control effects of Matsucoccus matsumurae in the forest with eleven different insecticides(Emamectin Benzoate-chlorfenapyr,Imidacloprid,Omethoate,Imidacloprid +Abamectin,DDVP+Omethoate)were studied by the method of trunk injection.The results showed that the control effect of all the insecticides was good,and which was related with the insecticide kinds,the doses and the applying time.Imidacloprid,Emamectin Benzoate+Omethoate(2%+20%)and Imidacloprid+Abamectin(4%+0.15%)had better control effects.The control effects reached 88.73%,86.98% and 93.03% within 19 days after a trunk injection(2mL/cm,respectively).The experiment showed that both the insecticides could be used in the control of Matsucoccus matsumurae.
