Abstract
Control effects of imidacloprid,beta-cypermethrin and buprofezin on Pseudophacopteron canarium were analyzed by the method of life table.The results showed that population trend indexes(I) of imidacloprid,beta-cypermethrin,buprofezin and the control were 0.414 8,0.832 8,4.990 8 and 6.392 5 respectively,which indicated the population of Pseudophacopteron canarium declined in the plots treated by imidacloprid and beta-cypermethrin,but that in the plots treated by buprofezin and the control rose by 4.990 8 and 6.392 5 times respectively.The interference index of population control(IIPC) of imidacloprid,beta-cypermethrin and buprofezin were 0.064 9,0.130 3 and 0.780 7 respectively,which indicated that the population in the plots treated by imidacloprid and beta-cypermethrin were only 6.49% and 13.03% of that in the control plots,so the control effects were good;population in the plots treated by buprofezin was 78.07% of that in the control plots,so its control effect was not ideal.
