日本松干蚧新寄主植物调查

The Investgation on New Host Plants of Matsucoccus matsumurae(Kuwana)

日本松干蚧疫区引进树种时,应以该树种是否抗日本松干蚧为主要引进标准。通过对抚顺地区近年来引进的松属造林树种进行调查、鉴定,确定引进的3个树种中,有2个树种是日本松干蚧的寄主树种。同时找出了抚顺地区8个松属林木树种是否寄主植物的一般区别。林业部门应加强管理,避免引进的树种成为新寄主植物现象的发生。

When new genus Pinus species were introduced to the area where the Matsucoccus matsumurae has occurred,we should know whether the species resist Matsucoccus matsumurae.We investigated the new Pinus species which were introduced whether it were infected by Matsucoccus matsumurae in Fushun area,confirmed that there are 2species become new host plants in 3species.And then we compared the different characters whether it were infected by Matsucoccus matsumurae among 8Pinus species.The forestry department should consider the new species resistant level for Matsucoccus matsumurae,to avoid the Pinus species as new host plants.
