松干蚧是松树的毁灭性害虫。它蔓延迅速。据初步统计,我区七个县松林受害面积约达25万余亩。这种害虫是当前我区林业大跃进的拦路虎,是林业战线上落实毛主席“备战、备荒、为人民”的伟大战略方针的大敌。多年来,一直没有找到有效的防治方法,致使危害面积日益扩大,危害程度越来越重,有的松林成片枯死。因此,各级领导均很重视松干蚧的防治。我们遵照毛主席关于“要认真总结经 Matsubara is a devastating pest of pine trees. It spread rapidly. According to preliminary statistics, the affected area of ​​Songlin in seven counties in our region is about 250,000 mu. This pest is a stumbling block to the Great Leap Forward in forestry in our region today. It is also the enemy of implementing the great strategic principle of “preparing for and preparing for the poor and for the people” of Chairman Mao on the forestry front. Over the years, no effective prevention and control measures have been found. As a result, the harms of the area are becoming more and more serious, and the damage is becoming more and more serious. Therefore, leaders at all levels attach great importance to the prevention and cure of pine cercariae. We follow Chairman Mao’s statement that “we should conscientiously sum up.”
