草履蚧对林木的危害及防治

草履蚧寄主丰富,一年发生1代,大多数以卵在土中越夏和越冬,翌年1月下旬至2月上旬,在土中开始孵化,若虫出土后沿茎杆上爬至梢部、芽腋或初展新叶刺吸危害。造成树势衰弱生长量降低,危害严重时造成树木死亡。若虫2龄后虫体蜡质增厚,农药不易渗透,防治难度大。我们采用综合防治,针对不同的虫期采取不同的防治方法,取得较好效果。

Hazards and Prevention and Control of Meatbug on Forest Trees

There are abundant hosts in the grass, and one generation occurs each year. Most of them use eggs to cross the summer and winter in the soil. From late January to early February of the following year, they begin to hatch in the soil. After the nymphs are unearthed, they climb along the stem to the tip, Bud axils, or the initial development of new leaf stinging hazards. It causes the tree to weaken and grow less, causing the tree to die when the damage is serious. After the nymphs are 2 years old, the wax of the insect body is thickened, and the pesticides are not easy to penetrate, and the prevention and control is difficult. We adopt comprehensive control and adopt different control methods for different insect stages, and achieve better results.
