With the rapid development of economic globalization, impacts of invasive alien insects on agriculture and forestry, ecological environment, socio-economy and human health are getting increasingly serious and of great concern. Over the last decade, risk assessment of invasive alien insects has become an important and fast-progressing research area in the invasive biology. The pest risk assessment is a comprehensive area of research, mainly involving invasion pathway, geographical distribution and climate- and host-suitable area, potential range of spread, and economic and ecological impacts, etc. The order-specific data reveal that Coleoptera is the largest taxon of insects with high risks, which accounts for 32.21% of the total studied species, followed by Diptera and Hymenoptera. Thysanoptera and isopteran are the least represented taxa, accounting for less than 2% of the risks. The analytical component of the assessment on the climate- and host-suitable area of invasive insects tends to be the most documented, accounting for 43.41% of the invasive risk assessment on insects. Further research on the risk assessment of invasive pests will be theoretically and practically important in preventing and interdicting the intrusion and spread of the alien pest insects.
