About the Author: Professor Yulin Gao is a Professor and Extension Entomology Specialist of the Institute of Plant Protection at Chinese Academy of Agricultural Sciences, Beijing, China. He is international known for his research on integrated pest management in potato and vegetable crops. He serves as the Vice President of APRS-IOBC and also serves as the Executive Editor of the well-known international journal Pest Management Science. Furthermore he serves as an editorial board member for a number of journals including Journal of Economic Entomology, Environmental Entomology and Journal of Pest Science.

Professor emeritus Heikki M.T. Hokkanen is a leading authority on biological control and integrated pest management. Currently he is affiliated with the University of Eastern Finland, Department of Environmental and Biological Sciences, as well as with the Southwest University, College of Plant Protection, Chongqing, China. He is the Founding Editor-in-Chief of the Springer book series "Progress in Biological Control", and of the Springer journal "Arthropod-Plant Interactions".
Dr. Ingeborg Menzler-Hokkanen works as a university researcher at the University of Eastern Finland, Department of Environmental and Biological Sciences, Kuopio campus, Finland. She has over 20 years of experience in entomological work with focus on biological control, integrated pest management, and pollinators. In addition, she has expertise in socio-economic questions (with a PhD in Economics), including regulation of new technologies, adoption of new technologies by end-users, and ethical questions.
