云南松干蚧是云南松(Pinus yunnanensis Franch.)的一种主要害虫,解放前美国蚧虫分类学家G.F.Ferris首先在云南安宁温泉云南松上采到,定名为云南松干蚧(Matsucoccus yunnanensis Ferris)隶属同翅目珠蚧科(Margarodidas),以若虫寄生于松树树干的翘皮下或皮层缝隙内,吸食树液,使松树生长衰弱或整株死亡。我们于1977年开始在昆明金殿林场对云南松干蚧的发生规律及防治进行了研究,现将2年来的初步成果介绍如下: Pinus yunnanensis is a major pest of pinus yunnanensis Franch. Before liberation, the American scale insect taxon GFFerris was first collected on Yunnan pine, Yunnan hot spring, and named as Matsucoccus yunnanensis Ferris, In order to Marjacididae (Margarodidas), nymphs parasitized in the trunk of the pine tree under the skull or cortical gap, take the tree liquid, the growth of the pine weak or whole plant died. We started in 1977 in Kunming Golden Temple Forest on the rules and control of Yunnan pine scale research, the initial results of the past two years are as follows:
