我国口岸小条实蝇属截获情况分析

Analysis of Ceratitis interceptions in Chinese ports

【目的】小条实蝇属害虫原产非洲,在我国无分布且具有一定的入侵风险。分析该虫在我国口岸的截获情况,能更好地利用已知实蝇截获数据防范实蝇人为传播。【方法】经动植物检验检疫信息资源共享服务平台查询,统计小条实蝇属的有害生物类别、截获途径及截获地区等。【结果】全国口岸共截获8种共计524批次的小条实蝇属害虫;地中海实蝇的截获批次数最多,为415批次,为小条实蝇属截获率的79.2%;截获的种类最多的国家来自尼日利亚,5种;截获批次最多的国家为南非,71批次;截获方式最多的为旅客携带物,占总批次的68.3%;在我国口岸中,广东口岸截获批次最多,占总数的57.4%。【结论】从今后防控的重点种类、加大查验力度、推广新技术在鉴定上的应用、应急预案等几个方面,加强针对该类有害生物的检验检疫措施。

【Aim】As quarantine officers,better use of the intercepted data to prevent the artificial transmission is the urgent task at present.No species of the genus Ceratitis,which is native to Africa,is currently present in China,while there have been border interceptions,so there is a certain risk of invasion.In this paper,we analysed interception data on Ceratitis charcterise propagule pressure.【Method】The data on species,interception modes and interception locations were acquired from the Chinese animal and plant inspection and quarantine information resources platform.【Result】A total of 8 species and 524 batches of Ceratitis have been intercepted,most frequently individuals of C.capitata(415 batches,79.2%of the total).The country with the most intercepted species was Nigeria,with 5 species.The country of origin with most of the intercepted batches was South African(71 batches).Most interceptions were made during passanger inspection(68.3%of all cases).Most interceptions were made at Guangdong(57.4%).【Conclusion】There exists a considerable propagule pressure by species of Ceratitis,so inspection should be strengthened,the application of new technology in identification recommended,and an emergency plan should be developed.
