摘要
松突圆蚧Hemiberlesia pitysophila Takagi是重要的检疫性有害生物,严重影响松树生长。纵带间伐套种相思类阔叶树改变了沿海黑松林的生境条件,增强林木抗性,阻隔了松突圆蚧的传播途径,使林间的松突圆蚧虫口密度由间伐前(2002年)的4.58头/针束,降低到次年的0.82头/针束,虫口减退率为82%,平均防治效果达85.68%,到2005年平均防治效果达94.23%。
Hemiberlesia pitysophila Takagi was an important quarantine pest causing great harm to pines. The forestation measures of interlogging and replanting broadleaf trees such as acacia in longitudinal stripes in pine forests could transform the habitat condition of Pinus tkunbergii, enhance the resistance of pines and impede the dissemination way of Hemiberlesia pitysophila. And the mean population density of Hemiberlesia pitysophila reduced from 4.58 per needle bunch before interlogging （2002） to 0.82 per needle bunch after interlogging （2003）, the receding rate was 82 %, the average control effect was 85.68% in 2003 and 94.23% in 2005.
