目的系统了解青岛港前湾港区入境国际航行船舶携带输入性医学媒介生物的情况,为制定有效的控制措施提供科学依据。方法在检疫锚地对入境的国际航行船舶携带输入性的鼠类、蚊类、蝇类、蜚蠊类进行调查,对采集的样本进行计数、分类和制作,并对结果进行统计分析。结果 2014年共调查323艘次入境国际航行船舶,输入性蚊类阳性率平均为19.8%(20/101);已鉴定确认的蚊种5种。输入性蝇类阳性率平均为83.0%(268/323);已鉴定确认的蝇种8种。输入性蜚蠊阳性率平均为16.4%(53/323);已鉴定确认的蜚蠊3种。输入性鼠类阳性率平均为0.93%(3/323);已鉴定确认的鼠种3种。结论调查证实入境国际航行船舶携带输入性医学昆虫的情况严重,具有阳性率高,种类多,风险大等特点,对此应给予高度关注。
Objective To understand the situation of imported medical vectors carried by international vessels entering the port of Qianwan in Qingdao Port and to provide a scientific basis for the formulation of effective control measures. Methods The imported rodents, mosquitoes, flies and cockroaches carried by imported ships were investigated at the quarantine anchorage. The collected samples were counted, classified and produced. The results were statistically analyzed. Results A total of 323 immigrant international vessels surveyed in 2014 showed an average positive rate of imported mosquitoes of 19.8% (20/101) and 5 species of mosquitoes identified. The average positive rate of imported sex flies was 83.0% (268/323). Eight species of flies were identified. The positive rate of imported cockroaches was 16.4% (53/323) on average; three cockroaches were identified. The positive rate of imported mice was 0.93% (3/323) on average; three species of rodents were identified. Conclusion The investigation confirmed that imported medical insects on international voyage ships are seriously ill with high positive rate, many kinds of diseases and high risk. Therefore, great attention should be paid to this.
