小木蠹蛾是我市行道树及庭院绿化树种的主要蛀干害虫,受其危害后,树木枝干干枯,常遇风折,甚至枯死,严重地影响了城市绿化和市容的整洁。多年来,我们采用多种农药,多种方法进行防治,效果均不理想。1980年我们在饲养木蠹蛾观察其生活史的过程中,发现此虫有害怕氨水的习性。因此,我们6月份用20%的氨水进行试验,结果效果很理想,氨水不仅能杀死木蠹蛾的幼虫,而且也能杀死蛹。与此同时,对馒头柳上的光肩星天牛也进行了试验,取得了同样的效果。
It is the main pest of pest-killing tree and courtyard afforestation species in our city. After being harmed by it, the branches of trees are withered, often suffer from wind-blown or even dead, seriously affecting the urban greening and the cleanliness of the cityscape. Over the years, we use a variety of pesticides, a variety of methods for prevention and treatment, the effect is not satisfactory. In 1980, we observed the life history of Lindgard moth and found that the worm was afraid of the habit of ammonia. Therefore, we tested with 20% ammonia in June and the result was very good. Ammonia not only killed the larva of the codling moth, but also killed the pupa. At the same time, the light on steamed bread willow star antelope has also been tested and achieved the same effect.
