樟树的白蚁危害及其防治初探

Preliminary study on the termite damage and control of Cinnamomum camphora

对中南林业科技大学校园绿化区内樟树的白蚁危害情况进行调查,采用喷液法和饵剂诱杀法对其进行防治并分析防治效果。结果表明:樟树的危害率为47.6%,危害种类为黑翅土白蚁和黄翅大白蚁。白蚁的发生情况呈现明显的季节变化,春秋季发生情况高于夏冬季节。喷液法处理操作简单,防治效果更优,但复发率较高;饵剂诱杀法的复发率较低,可回收利用,但防治效果低于喷液法。建议可采取两种方式交替处理白蚁,先以饵剂诱杀法处理。

This study investigated the termite damage of Cinnamomum camphora in the green land of Central South University of Forestry and Technology, and used spraying method and bait killing method to control the termites. The results showed that the damage rate of Cinnamomum camphora was 47.6%,and the damage species were Odontotermes formosanus and Maerotermes bavneyi. The occurrence of termites in spring and autumn was higher than that in summer and winter. The spraying method was simple and effective, but the recurrence rate was high. The recurrence rate of bait killing method was low and can be recycled, but the control effect was lower than that of spraying method;It is suggested that two methods can be used to treat termites alternately, while bait killing method should be used first.
