星天牛和光肩星天牛是阔叶树的两个重要蛀干害虫。它们的幼虫在树干钻蛀孔道,影响树木生长和木材工艺价值,被害严重的树木常风折、死亡,给林业生产造成很大损失。以往防治这两种害虫常使用滴滴涕、六六六、一○五九等农药。由于这些农药会造成环境污染,正在被逐步限制和停止使用。为了寻找高效、低毒、低残留的新农药代替它们,使用辛硫磷、螟铃畏、杀虫脒和杀虫净进行了防治星天牛成虫的试验;用辛硫磷、氧化乐果、害扑威进行了防治光肩星天牛幼虫的试验。结果如下:
Asteraceae and Shine Asclepias are two important pests of the broad-leaved tree. Their larvae drillage holes in the trunk, affecting the growth of trees and the value of the timber craft. The severely damaged trees often wind up and die, causing great losses to forestry production. In the past, these two kinds of pests were often used as pesticides such as DDT, 666 and 1059. As these pesticides can cause environmental pollution, they are being gradually restricted and stopped being used. In order to find a new pesticide with high efficiency, low toxicity and low residue to replace them, the test of adults of Asterius was carried out by using phoxim, insecticidal amidine and insecticidal net. Using phoxim, omethoate, Preventing the loopholes carried out prevention and treatment of light Shijiazhuang Tian Tian larvae test. The result is as follows:
