ABSTRACT

Sydney has a high plant biosecurity risk due to the volume of international freight and postal items. Additionally, a high number of tourists enter Australia through Sydney. In 1995, an array of fruit fly surveillance traps was established to monitor for exotic fruit fly incursions. Here, the number of detections of the fruit fly subfamily Dacinae (Insecta, Diptera, Tephrididae) was reviewed for the period between 2010 and 2019. The results revealed that no exotic fruit flies were detected during this period. However, many established species were detected and species present were placed into international standards. Bactrocera tryoni, B. cacuminatra, Dacus absonifacies, and D. aequalis were classified as established due to a large number of specimens trapped. Sydney was likely to be an area of low pest prevalence for B. neohumeralis in some years and pest free in other years. Low numbers of B. bancrofti, B. brunnea, B. jarvisi, and B. mayi were trapped, and Sydney was likely to be classified free from these species based on international standards. Also, trapping records indicated that Sydney was free from D. newmani however this species was known to occur in inland NSW. Bactrocera bryoniae and B. endiandrae were likely to be incursions that did not establish in most years.

摘要

由于国际货运量和邮政量的大量增加，悉尼的植物生物安全风险很高。此外，大量游客通过悉尼进入澳大利亚。1995年，建立了一系列果蝇监视陷阱，以监视外来果蝇的入侵。在此，我们回顾了2010年至2019年期间发现的果蝇亚科（昆虫科，昆虫科，双翅目，天蛾科）的数量。结果表明，在此期间未检测到外来果蝇。但是，发现了许多已建立的物种，并将存在的物种列入了国际标准。昆士兰实蝇，B. cacuminatra，Dacus absonifacies和D.麦娘由于捕获了大量标本而被归类为已建立。在某些年份，悉尼可能是新肱虫的有害生物低发地区，而在另一些年份则是无虫害的地区。数量少B.氏丝虫，B.褐斑，B. jarvisi和B.马邑人被困，和悉尼很可能基于国际标准，这些品种可以自由地进行分类。另外，诱捕记录表明悉尼没有纽曼氏梭状芽胞杆菌，但是已知该物种存在于新南威尔士州内陆。Bactrocera bryoniae和B.endiandrae可能是大多数年来未建立的入侵。
