热烟雾杀灭德国小蠊的现场试验

Efficacy of hot fog against Blattella germanica

目的 :观察实施热烟雾技术现场杀灭德国小蠊的效果。方法 :现场用 6HYC— 2 5型热烟雾机、右旋苯氰菊酯、胺菊酯复配的烟雾制剂 ,间隔 30d 2次杀灭德国小蠊 ,粘捕法测定杀灭前后德国小蠊的密度情况 ;结果 :杀灭前的现场密度为 18 88只 /张·夜 ,灭后整体密度降为 0 0 1只 /张·夜 ,杀灭率达 99 4 9%。结论 :热烟雾技术灭效显著 。

Objective:To observe the efficacy of hot fog against Blattella germanica in the field. Methods: Using 6HYC 25 type hot smoke machine and d cyphenothrin, tetramethrin in the field. It took 30 days to kill Blattella germanica for 2 times. Results: Before experiment, the density of Blattella germanica was 18.88 insect/night. After the application of hot fog technique, the density declined to 0.01 insect/night. The mortality was 99.49%. Conclusion: The hot fog technique was of great efficacy against Blattella germanica and it should be further generalized.
