打孔注药防治蛀干害虫打孔注药防治蛀干害虫是一种行之有效省工、省时、省钱的技术，同时还有效地兼防了枝叶害虫，对环境无污染，对树木产生的药害也很轻微。有科技人员在山东菏泽防治泡桐大袋蛾中，连续几年使用此方法，取得较好效果。近两年在济南市对受光肩星天牛危害的400余株垂柳和受桑天牛危害的毛白杨进行注药防治，灭虫率在95%以上，取得了很好的效果。具体防治方法如下：1．防治时间：准确掌握防治时间是保证防治效果的关键，要根据各地区蛀干害虫的羽化期和卵期来确定防治期。如在山东、河南、河北、辽宁、天津、北京等省市，光肩星天牛和桑天牛羽化高峰期是在7月下旬，卵期分别为10天和13天，这样注药防治期以7月下旬的初期和中期幼虫出现的时间为最佳防治时期。这时如果不下雨可全天候防治。2．药具准备：准备一根长30至40厘米，直径12至20毫米的钢钎，一把铁锤，一支10至15毫升的吸药器或医用注射器。准备药品如久效磷或吡虫啉等或其他内吸型农药。3．打孔注药方法(1)用钢钎在受害树的横根基部垂直打一个深入木质部3至4厘米孔，每株树打2至4孔，较大树可适当增加孔数。(2)根据不同直径的树木注入不同量的药液。如：直径10至15厘米，可注入久效磷原液5至7毫升，直径11至20厘米注入7至10毫升，直径21至30厘米注入10至15毫升。用其它种药可参照久效磷的原液注入量酌情使用。注药后用一片树叶盖在孔上并压上土。4．防治次数：一年两次，除7月下旬一次外，在8月中下旬再注一次。通过这两次防治完全可以达到有虫不成灾的目的。——摘自《中国花卉报》2002.9/28
