【Aim】 Blueberry gall midge, Dasineura oxycoccana (Johnson), is a important pest in buleberry. It has rapidly spread around the world. With increasing introduction and planting area of blueberry in China, the invasion and occurrence risk of D. oxycoccana in China increases. 【Method】 Following the pest risk assessment method, qualitative and quantitative analysis of invasion risk of D. oxycoccana were conducted, a comprehensive risk value (R) was calculated, and risk level was determined. 【Result】 D. oxycoccana is a great potential threat to the buleberry plantations in China with the risk value of 2.12. 【Conclusion】 D. oxycoccana is considered a high-risk pest. Available risk management measures must be established in order to prevent its introduction to China.
