Abstract: The life table grouped by various factors and the interference index of population control were used as the basic sampling parameters to evaluate the controlling effects of compounds of foliage fertilizer mixed with imidacloprid and Lambda-cyhalothrin respectively on Pseudophacopteron canarium. Results showed that the population indices of P.canarium were all smaller than 1 in the six test areas, which are Lambda-cyhalothrin and imidacloprid mixed with micro-nucleotide respecitively, Lambda-cyhalothrin and imidacloprid mixed with 15% green vitriol respecitively, Lambda-cyhalothrin and imidacloprid treated separately. Besides, the trends of population numbers are declining in all six test areas. In the contrast, the population numbers increased tremendously with the speed of 6.39 times in the control area. Comparing to the control area, the interference indices of population control for the six test areas were 3.18%,3.71%,3.85%,4.75%,6.23% and 6.49%, respectively. It is suggested that mixture with foliage fertilizer displayed better insect-control effect than the single insecticides applied on the trees.
