Preventing the introduction of new and harmful exotic species.
The introduction and spread of new and exotic species beyond their native range can have severe negative environmental consequences, and the drivers of invasion show little sign of abating. In Australia, for example, the recent arrival of the South American Fire Ant (Wylie & Janssen-May 2017) and myrtle rust (Carnegie et al. 2016) are clear examples of the ongoing risk of introduced species. The Fire Ant was introduced to South East Queensland in 2001 (Click here for more), and myrtle rust to NSW in 2010 (Click here for more). There are a number of invasive pathogens and insects that have the potential to significantly damage native biodiversity in Australia and elsewhere (McGeoch et al. 2015; Burgess & Wingfield 2017).
We are collaborating with the Invasive Species Council to identify future invasion risks and their associated pathways of introduction – for alien insects and plant pathogens of environmental native biodiversity and ecosystems concern. The project will adopt a comprehensive species by pathways assessment (Wingfield et al. 2015; McGeoch et al. 2016), and develop the structure for an information platform for sustainable ongoing delivery of data to support pre-border risk assessment.

Report lifts lid on Australia’s international bug superhighway
A new report has identified an international ‘bug superhighway’ capable of carrying a large variety of environmentally destructive overseas insects into Australia.
The study, led by the Monash University School of Biological Sciences, rated the environmental harm being caused by 100 of the worst overseas insect species and recommends a range of actions to keep them out of Australia.

Bug SuperHighways’ letting environmental pests into Australia – ABC Radio National
Australian and international researchers have analysed the world’s 100 most damaging environmental pests, and their pathways into Australia via so-called ‘Bug SuperHighways’. With pests like Yellow Crazy Ants and Fire Ants already here and proving difficult and expensive to eliminate, the lead author of the report, Melodie McGeoch, says that Australia is under extreme threat from invasive environmental species.

Global leaders in insect invasion ecology convened in March at Monash University for the Environmental Impact Classification Workshop for Alien Insects. The objective of this workshop was to apply a standardised approach to classify alien insect species according to the size of their environmental impacts, based on a suite of standard impact mechanisms. It forms part of a larger project focussed on assessing pre-border risks to Australia from invasive alien insects, but the workshop encompassed alien insects that cause environmental harm anywhere in the world. A special Q&A debate – titled “Ants, Bugs & Biters” – was also held as part of the workshop, in association with the Invasive Species Council.
