预防介壳虫最有效的方法是用溴化甲烷熏蒸栽植材料。根据害虫的死亡率确定熏蒸的效率。不久以前还是根据熏蒸后15—20天测定谷象死亡率或干缩的介壳虫体的方法来确定死亡的梨圆介壳虫,对此所采用测定喙搏动(1964.H.Fieher),以碘溶液染虫体及中性溶液染马氏管等方法,既费力且不便推广使用。七十年代初期乌克兰科学院动物所与赫尔松检疫实验室一起拟定了用比色法确定介壳虫的死亡率,即在熏蒸3—5天后判断其效率。用 PH 值相当于10.5的乙二醇缓冲液配
The most effective way to prevent scale insects is to fumigate the planting material with methane bromide. According to the mortality of pests to determine the efficiency of fumigation. Not long ago, the death of Pest Pest was also determined on the basis of the mortality of cereal grains or the shrinking scale insects 15-20 days after fumigation. For this purpose, beak beetles were used to measure Beak Beat (1964.H.Fieher) Solution of infected insects and neutral solution with Markov tube and other methods, both laborious and inconvenient to promote the use. In the early 1970s, the Institute of Zoology of the Academy of Sciences of Ukraine together with the Kherson Quarantine Laboratory developed a colorimetric method for determining the mortality of scale insects, ie, determining the efficiency after fumigation for 3-5 days. Use a pH equivalent to 10.5 in ethylene glycol buffer
