目的 :观察滞留性喷洒灭蝇技术的灭蝇效果、一年中不同时期采取滞留性喷洒灭蝇的效果和滞留性喷洒与空间喷洒效果及成本比较。方法 :在中小饭店、居民区垃圾箱和饲养场采用滞留性喷洒方法灭蝇 ,以粘蝇纸、捕蝇笼和目测法观察灭蝇效果。结果 :在中小饭店、居民区垃圾箱和饲养场采用滞留性喷洒技术灭蝇不仅可以有效降低试验现场的苍蝇密度 ,灭蝇效果至少可维持 1.5个月 ,而且垃圾箱灭蝇还可以降低周围居民室内的苍蝇数量 ;在苍蝇繁殖高峰前施用滞留性喷洒 ,可以取得更佳的灭蝇效果 ;在获得相同灭蝇效果的情况下滞留性喷洒可以比空间喷洒节省人力和药费。结论 :滞留性喷洒是蝇类防制中值得推荐的灭蝇方法
OBJECTIVE: To observe the effects of decontamination by spraying decontamination technique, the effects of decontamination spraying and spraying at different times of the year, and the comparison of the effectiveness and cost of decontamination and space spraying. Methods: The stagnant spraying method was used to kill flies in small and medium-sized hotels and residential areas, and the fly-killing effect was observed with fly-fly paper, catching fly cage and visual inspection method. Results: In small and medium-sized hotels, residential dwellings and farms using decontamination spray technology to fly not only can effectively reduce the test site flies density, the effect of killing flies can be maintained for at least 1.5 months, and dustbin trash can also reduce the surrounding residents The number of flies in the house; the use of retention spraying prior to the peak of flies breeding resulted in better flies-killing effects; and the retention spraying could save manpower and medication more than space-spraying with the same flies-killing effect. CONCLUSION: Retention spraying is a recommended method of fly suppression in the control of flies
