吡虫啉打孔注药防治光肩星天牛成效分析

Analysis of the Effectiveness of Imidacloprid Drilling and Injection in Controlling the Anoplophora glabripennis

为了筛选出对光肩星天牛有效的防治药剂,试验选用10%吡虫啉原液和10%高效氯氰菊酯两种药剂,采用打孔注药的方法,进行光肩星天牛防治效果对比分析。结果表明,采用10%吡虫啉原液连续防治3年,被害株率从76.67%下降到0.95%,平均单株虫孔数从3.97个下降到0.29个,胸径20 cm以下的被害树木可达到完全消除危害的效果。

In order to screen effective control agents for Anoplophora glabripennis,10%imidacloprid stock solution and 10%high-efficiency cypermethrin,were selected for the experiment.The control effect of Anoplophora glabripennis was compared and analyzed by using a method of drilling and injection.The results showed that using 10%imidacloprid stock solution for consecutive 3 years,the rate of damaged plants decreased from 76.67%to 0.95%,and the average number of insect holes per plant decreased from 3.97 to 0.29.Damaged trees with a diameter of less than 20 cm and the height below 1.3 meter can be completely cured.
