Abstract: Vector biology is a rapidly developing branch of life science, and vector insects of medical and agricultural importance are important research targets. This article reviews the research progress in vector biology and vector insects, including the research background and significance, and research history and current status worldwide, and proposes the key areas and questions for further research, aiming to provide a basic information frame in vector biology and vector insects, to promote the research and technology development in the field, and to enhance the control level of vector organism and vector-borne diseases.

Key words: Vector biology, vector insects, virus, vector-borne disease, prevention and control
