| Abstract: | The occurrence and damage of Asemum amurense in Fengning County,Hebei Province were briefly discussed and the control advices were given.A.amurense caused great damage on Pinus tabulaeformis.The attack rate of the pest was over 50% and the population density was about 126 insects per tree.Poor site condition,continuous drought and the lack of the knowledge about the insect's biological and ecological characters and monitoring techniques account for the serious damage. |
| Keywords: | Asemum amurense Pinus tabulaeformis attack rate population density |
