Dispersal of harmful fruit fly pests by international trade and a loop-mediated isothermal amplification assay to prevent their introduction.


Global trade of plant products represents a major driving force for the spread of invasive insect pests. This visualisation illustrates the problem of unintended dispersal of economically harmful fruit fly pests (Diptera: Tephritidae) using geospatial tools and a time series of interception data from the Swiss import control system. Furthermore, it reports the development of a molecular diagnostic assay for rapid identification of these pests at points of entry (POEs) such as sea- and airports as a prevention measure. The assay reliably differentiates between target and non-target species within one hour and has been successfully evaluated for on-site use at a Swiss POE.
