| 摘 要： | 青海云杉的种实害虫有十几种，危害严重的有三种，即云杉球果小卷蛾、云杉蛀果斑螟和云杉梢斑螟，主要发生在甘肃祁连山林区。本文经过调查，根据青海云杉和种实害虫的生物学特性，提出加强青海云杉林的经营管理，尽量减少广谱性化学药剂的大面积使用；尽可能多的应用营林技术为主的、不杀伤天敌的防治措施，以达到青海云杉种实害虫综合治理的良性循环；并提出青海云杉种实害虫综合治理的策略、原则以及评价青海云杉种实害虫综合治理的步骤和方法。

| Abstract: | There are over 10 kinds of Picea crassifolia seed pests,among them Psevdotomoides strobilellus, Dioryctria schuetzeella and Assara tere-brella are mainly occuring in Qilian mountain forest zone in Gansu and seriously damaging the trees.Based on biological characteristics of Picea crassifolia and its seed pests,some efficient measures to control the seed pests are put forward,including to strengthen forest manage-ment,minimize widespread use of chemical pesticides,and apply control ffleasures as much as possible by focusing on afforestation techniques and pretection of nature enemies. In addition,this paper also put forward the strategy and principle of integrated control of the seed pest, as well as steps and methods of evaluating integrated control. |
