黄斑星天牛 (Anoplophoranobilis)硫酰氟熏蒸的毒力试验结果说明 ,当熏蒸时间为2 4h ,4.4℃、1 0 .0℃、1 5.5℃和 2 1 .1℃条件下推算出死亡机率值 9要求的CT值分别为70 0 4.2 0、3 2 96.97、974.63和 52 7.0 4g .h/m3;当熏蒸时间为 48h ,4.4℃和 2 1 .1℃分别为 2 82 8.2 2和 50 5.45g .h/m3。室内验证试验中 ,1 5.5℃和 2 1 .1℃投药剂量为 1 0 4g/m3,能够全部杀灭杨树携带的黄斑星天牛幼虫、蛹 ,以及芳香木蠹蛾东方亚种 (Cossuscossusorientalis)和杨干透翅蛾 (Spheciasiningensis)幼虫 ;而在 1 0℃以下 ,黄斑星天牛或芳香木蠹蛾东方亚种和杨干透翅蛾幼虫没有完全死亡。
The virulence test results of fumigating with sulfuryl fluoride from Anoplophoranobilis showed that when the fumigation time was 24 h, 4.4 ℃, 10.0 ℃, 11.5 ℃ and 21.1 ℃, the probability of death was calculated 9 required CT values were 70 0 4.2 0,3 2 96.97,974.63 and 52 7.0 4g .h / m3 respectively; when the fumigation time was 48 h, 4.4 ℃ and 21.1 ℃ were 2 82 8.2 2 and 50 5.45g respectively .h / m3. In the indoor validation test, the larvae, pupae of Populus cydiae lanceolata carried by poplar trees and the Cossuscossus orientalis species were all killed at 1 5.5 ℃ and 21.1 ℃ at a dose of 104 g / m3. And the larva of Spheciasiningensis. However, the larvae of Asclepias aurantiacus or Codonopsis pumila were not completely dead below 10 ℃.
