浅圆仓准低温低氧状态低剂量硫酰氟熏蒸杀虫试验

LOW DOSE SULFURYL FLUORIDE FUMIGATION AND INSECTICIDAL TEST UNDER QUASI LOW TEMPERATURE AND LOW OXYGEN IN SQUAT DEPOT

采用低剂量硫酰氟在准低温且低氧小麦仓中进行杀虫试验,研究硫酰氟熏蒸杀虫效果。结果表明:低剂量硫酰氟在准低温且低氧环境中对谷蠹、玉米象、锈赤扁谷盗等常见储粮害虫成虫F_(0)代致死率达100%,对其F_(1)子代抑制效果为100%;对小麦质量指标及食品安全指标无影响。

The insecticidal effect of sulfuryl fluoride fumigation was studied by using low-dose sulfuryl fluoride in quasi low temperature and low oxygen wheat barn. The results showed that low-dose sulfuryl fluoride in the quasi low temperature and low oxygen environment had 100% mortality rate of F_(0) generation and 100% inhibition effect on F_(1) generation of common stored grain pests such as bark beetle, corn weevil, rust red flat grain thief, etc;it had no effect on wheat quality index and food safety index.
