The movements of unwanted pests between different continents are being accelerated by the global climate change and ever-increasing international trades, which has also been facilitated by the recent increase of FTA and other trade agreements. Many invasive pests cause serious economic losses and ecological disturbance in invaded rural and natural areas. Since the uncertainty of potential impact of invasive pests, it would be extremely useful if the priority of invasive quarantine pests can be predicted for the efficient surveillance and eradication processes. We are initially analysed national and foreign examples to evaluate the current system of pest prioritization of national quarantine pests. Also here we suggests evaluation platforms for selecting high priority exotic pests.
