介壳虫是我县柑桔的重要害虫之一,尤以矢尖蚧为害普遍而猖獗。由于介壳虫具有较厚实的腊质外壳大多数药剂对介壳虫防治效果都较差。我县农牧局使用瑞士生产的新农药——速扑杀,防治柑桔多种介壳虫的防效高达90％以上。 Scale insects is one of the most important pests of citrus in our county, especially the common and rampant infestation of arrowhead scale. As the scale insects have a thicker waxy shell most pesticides on scale control effect is poor. Our County Bureau of Agriculture and Animal Husbandry use of new pesticides produced in Switzerland - speed culling, prevention and control of citrus variety of scale insects, the anti-efficiency as high as 90%.
