Abstract: Objective To prevent the transmission of diseases by the breeding vectors and their carried pathogens on an entry international navigation container ship. Methods In October 2016, an entry international container ship seriously infested with vectors in the phase II dock of Nansha port in Guangdong, China was disinsectized based on the breeding status of vectors and the structure of ship. Sulfuryl fluoride fumigation was applied at a concentration of 8 g/m³ for 24 h in the cargo compartment and living areas. Cypermethrin insecticide spray (40 mg/m², 30 min) was applied twice (before unloading and before fumigation) in the areas where it was unsuitable for fumigation, such as main engine room, deck, storeroom, anchor chain room, and lifeboat. Results The mortality rates of test insects and test rodents, which were used to evaluate the effect of sulfuryl fluoride fumigation, were 100% after 24 h of sulfuryl fluoride fumigation. No living vectors were observed in the spray areas by vector monitoring before departure. Conclusion The effect of sulfuryl fluoride fumigation on the entry international navigation container ship is satisfying, providing a valuable experience for the fumigation of large international navigation ships.

摘要： 目的 防止某入境国际航行货轮上孳生泛滥的病媒生物及其携带的病原体入境传播疾病。方法 根据病媒生物侵害情况及货轮结构，2016年10月在广东省南沙港二期码头对入境的一艘大型集装箱运输船舶实施除虫处理，对其货舱和生活区采取硫酰氟8 g/m³进行熏蒸24 h；对主机舱、甲板面、物料间、锚链间和救生艇等不便于熏蒸部位，在卸货前和熏蒸前分别实施1次喷洒除虫，采用氯氰菊酯杀虫剂进行喷洒处理，药剂浓度为40 mg/m²，作用时间为30 min。结果 采用硫酰氟熏蒸24 h后，用于进行熏蒸效果评价的试虫、试鼠死亡率均为100%；喷洒区域在船舶离港前，经过病媒生物监测，未发现活体病媒生物。结论 对国际航行货轮的硫酰氟熏蒸处理效果理想，为以后国际大型船舶的熏蒸处理提供了宝贵经验。
