| 摘 要： | 云杉树叶象是白龙江林区森林苗辅的主要地下害虫，以云杉属苗木为寄主，在该地区1年发生1代。幼虫在苗木根系周围的土壤中越冬，以越冬幼虫在每年春季取食苗木根系而造成主要危害。该虫发生与苗龄、海拨、坡向等因素有关。防治应采取苗木检疫、虫情测报、对苗木进行土壤处理及化学防治等措施。

| Abstract: | Phyllobius sp. one of main underground pest in Bailongjiang forest nursery, parasitical in Picea seeding. It occurred 1 generation per year and its larva survived the winter in soil around the root of Picea seeding. In spring the seedling damages was caused mainly by the larva feeding the root of Picea. Its occurrence was related to seedling ages, altitude, and face of slope. It should be controlled by seedling quarantine, pest insect forecast, soil disinfections and chemicals. |
