Water-filled barriers are ubiquitous throughout Australia and are used primarily for pedestrian traffic delineation use on work areas, detours, sporting events, construction projects, parking areas, airports etc. Even though barriers are emptied of water for their return to the hiring depot, desiccation resistant eggs of Aedes could be a convenient system for extending the range of dengue mosquitoes. At present, we have no idea of the distances which orders of barriers may travel, and whether (for example) Aedes aegypti, the primary dengue vector, could be transported from positive towns such as Injune, Roma and Emerald to presently negative towns and cities such as Toowoomba, Ipswich and Brisbane. Could they travel further afield? Thus, knowledge of transportation pathways for exotic mosquitoes Aedes aegypti and Aedes albopictus is critical for vector-borne disease control and for the development of prevention strategies.
