Abstract

As international trade and travel increase around the world, invasive species detections and incursions are increasing in frequency. Here we document the first detection and incursion within Australia by the Polyphagous shot-hole borer (PSHB), Euwallacea fornicatus (Eichhoff, 1868) (Coleoptera: Curculionidae: Scolytinae), an ambrosia beetle, and two of the associated fungal species; Fusarium sp. [AF18], and Graphium euwallaceae. All three exotic species were detected in a confined region within Perth, Western Australia, and represent a co-invasion. This multispecies incursion into one of the world’s most remote cities highlights the rapid increase in biological invasions globally and the pressures that urban, agricultural, and native environments face from invasive species.
