〔目的〕了解输入性媒介昆虫携带病原体情况,为卫生检疫执法提供技术依据,采取有针对性的卫生处理措施,保障国境口岸卫生安全。〔方法〕采用生理盐水直接涂片法,对捕获的媒介昆虫逐一进行寄生虫虫卵检测。〔结果〕从韩国釜山港来的“凯越”号(KAIYUE)货轮上捕获89只苍蝇,从2只大头金蝇中分别检测出肝吸虫卵和蛔虫卵。〔结论〕我国国境口岸首次从入境媒介昆虫中检测到寄生虫虫卵,提示今后应加大依靠技术手段进行检疫执法的力度,保障国境口岸卫生安全。 [Objective] To understand the situation of imported vectors carrying pathogens and provide technical basis for health quarantine and law enforcement and take targeted health measures to ensure the health and safety of border crossings. [Method] The direct smear method of physiological saline was used to detect parasite eggs one by one on the captured media insects. [Results] Eighty-nine flies were captured from the KAIYUE freighter coming from Busan Port, South Korea, and hepatic and ascaris eggs were detected from the two goldfly, respectively. [Conclusions] Parasitic eggs were firstly detected from the imported media insects at the border crossings of our country at the border crossings, suggesting that efforts should be made to enforce quarantine and law enforcement by means of technical means in the future so as to ensure the health and safety of cross-border ports.
