In recent years, Drosophila suzukii, has become an important fruit pest worldwide. The pest has been introduced into many countries in Europe and Americas during the recent years. This pest caused serious harm to the local fruit production. Meanwhile, the damage caused by this pest in China has been becoming more and more serious. According to the research progress on D.suzukii, the invasion process, the invasion characteristics, and management measures including physical control, biological control, and chemical control of the pest were reviewed. The research progress showed that D.suzukiihas strong ecological adaptability, rapid spreading ability, and can cause severe damage. The future research on the invasion biology of this fruit fly is needed, which will be helpful to the integrated management of this pest.
