In order to control of Stephanitis pyriodes which is the main pest of Rhododendron simsii,37% beta-cyper-methrin malathion,1.8% avermectin,5% imidacloprid·cypermethrin and 10% imidacloprid were selected for toxico-logical test and laboratory experiments on Stephanitis pyriodes. The results showed that,all of the four pesticides were suit for controlling of Stephanitis pyriodes,the control effect of four pesticides were 100% after 5 days sprayed. The control effect of 5%imidacloprid and cypermethrin mixtures EC diluted by 1 000 times were 93.3%,98.9%and 100%after 1 day,2 days and 3 days sprayed respectively. The toxicity of four pesticides was 5% imidacloprid·cypermethrin>37%beta-cypermethrin malathion>1.8% avermectin>10% imidacloprid.
