自1954年在加利福尼亚州首次发现热带绦虫果蝇以来，在该州330个城市的3348个地点共发现4属17种和11 386只（成虫/幼虫）。我们从历史捕获模式和建模的空间制图分析中得出结论，尽管州和联邦机构针对这些害虫进行了250多个紧急根除项目，但至少有五种，多达九种或更多的绦虫物种已经建立并广泛分布，包括地中海，墨西哥和东方果蝇，可能还有桃，番石榴和瓜类果蝇。我们概述并讨论了我们结论的证据，特别关注入侵的增量，慢性和潜伏性，涉及超小，几乎无法检测到的种群。最后，我们考虑了我们的研究结果对入侵生物学和基于科学的入侵政策的影响。
Since 1954, when the first tropical tephritid fruit fly was detected in California, a total of 17 species in four genera and 11 386 individuals (adults/larvae) have been detected in the state at more than 3348 locations in 330 cities. We conclude from spatial mapping analyses of historical capture patterns and modelling that, despite the 250+ emergency eradication projects that have been directed against these pests by state and federal agencies, a minimum of five and as many as nine or more tephritid species are established and widespread, including the Mediterranean, Mexican and oriental fruit flies, and possibly the peach, guava and melon fruit flies. We outline and discuss the evidence for our conclusions, with particular attention to the incremental, chronic and insidious nature of the invasion, which involves ultra-small, barely detectable populations. We finish by considering the implications of our results for invasion biology and for science-based invasion policy.
