近年来,在北方地区蛀干害虫猖獗发生,我省多种林木及果树受杨大透翅蛾、芳香木蠹蛾、光肩星天牛、桃红颈天牛等害虫严重为害,造成树木枯梢、风折、枯死,已成为一些地区造林成败的关键因素之一。当前,防治蛀干害虫幼虫主要采用药泥、药棉塞孔,药水注射等方法,由于虫道较深且弯曲,虫粪堵塞等原因,药剂难及虫体,因而杀虫效果不够理想,野外操作不方便也不安全。鉴此,我们试制了一种成本低、杀虫率高、使用方便而且安全的熏蒸毒鉴。从1981-1983年对四种蛀干性害虫幼虫进行了近100亩的防治
In recent years, rampant pests of borers occur in northern China. Many kinds of trees and fruit trees in our province are severely damaged by pests such as Populus euphratica, aphid, Coccinella septempunctata, Withered, has become one of the key factors in the success of afforestation in some areas. At present, the main methods for preventing and controlling borer larvae are insecticide, insecticide effect and insecticidal effect, which are mainly due to the methods of medicinal mud, cotton wool plug hole and syrup injection because of the deep and curved wormhole and insect blockage, Inconvenient or unsafe In view of this, we trial-produced a low cost, high insecticidal rate, easy to use and safe fumigation. From 1981 to 1983, nearly four hundred species of stem borer larvae were treated and controlled
