摘要
针对沙棘木蠹蛾的生物学特性 ,采用干基喷雾、浇根、排粪孔注药、熏蒸等化学防治方法防治其幼虫 ,进行了大量野外试验。试验结果表明 ,在这些防治方法中 ,只有磷化铝熏蒸可称得上是一种经济、有效、可行的防治方法。夏季日均温在 2 1～ 2 5℃时 ,以每株树 1丸 ( 3 2 g)的剂量进行根部熏蒸 ,防治效果可达 82 61 % ,防治成本为 1 91 4元 /hm2 。
According to the bionomics of Holcocerus hippophaecolus,chemical control experiments were done in the field.Among the control methods of trunk spray,stem injection,irrigation and fumigation,fumigating with aluminium phosphide was proved to be economic,effective and feasible.When the (average daily) temperature reached 21～25 ℃ in summer,the control effect was 82.61% at the dose of (1 pill)(about 3.2 g) of aluminium phosphide per tree and the control cost was only 191.4 yuanhm^2.
