马尾松毛虫是广西松树的主要害虫。本文通过总结三十多年来的防治实践,结合当前区情,提出我区防治松毛虫中开展综合治理的必然性、理论基础及其途径。 从目前防治松毛虫工作现状及存在问题看到,我区自从1971年推广白僵菌防治松毛虫工作以来,取得一定成绩,但也存在一些问题,致使有些地方盲目大量使用化学农药,使松毛虫产生了抗药性,引起了虫口回升和林内次要害虫猖獗等“农药恶性循环”,虫害始终未能解决。 第二部分提出综合防治理论和指导思想,确定它是一种以生态学为基础的防治策略,采
Masson pine caterpillar is the main pest of Guangxi pine. This article summarizes the prevention and control practices over the past thirty years, combined with the current situation in the region, puts forward the inevitability, theoretical basis and approach of comprehensive prevention and control of pine caterpillars in our district. From the present status of the prevention and control of pine caterpillars and the existing problems, we have made some achievements since the promotion of Beauveria bassiana in 1971. However, there are also some problems that lead to the blind use of chemical pesticides blindly in some places, Resulting in resistance to pesticides, causing a rebound in insects and rampant secondary pests in the forest “vicious cycle of pesticides,” pests have not been resolved. The second part puts forward the theory and guiding ideology of comprehensive prevention and control to make sure that it is a kind of ecology-based prevention and control strategy.
