Prof. Heikki Hokkanen is a professor of agricultural zoology at the Faculty of Agriculture and Forestry, University of Helsinki. He holds a Lic. Phil. degree in ecology and natural resource management (1978, Univ. Jyväskylä, Finland), and a PhD in applied entomology (1983, Cornell University, Ithaca, NY, USA). After his PhD Hokkanen stayed for extensive periods as a visiting scholar at the Institute of Biological Control (Darmstadt, Germany), CABI Institute of Biological Control (Silwood Park, UK), University of Kiel, Germany, and at the OECD Directorate for Agriculture (Paris, France). In Finland his main work has been carried out first at the University of Kuopio (deputy professor), then at the Agricultural research center of Finland (Jokioinen), and since 1990 as a professor at the University of Helsinki.

His main interest and focus of work has been on all aspects of biological control, with emphasis on insect control. In recent years his interests have also covered pollinators, and plant-derived bioactive compounds with an aim at plant protection applications. He has a long track record of coordinating international collaborative research, e.g. over ten years at the OECD Directorate for Agriculture (Paris). He coordinated the EU-project ERBIC (FAIR5), coordinated the FP7 project ‘ForestSpeCs’, and has participated in five other EU-RTD projects. Hokkanen is member of the national Plant Protection Advisory Board, Ministry for Agriculture and Forestry. Hokkanen is an active player in scientific publishing: Editor-in-Chief of BioControl (1997-2006); Founding EiC of Arthropod-Plant Interactions (2006-), editor of book series ‘Progress in Biological Control’, all by Springer. He is the only Finnish entomologist so far, who has published two papers in the Annual Review of Entomology (1991, 2006). Professor Hokkanen has experience in organizing large scientific meetings, as he was the Chair of the Organizing Committee for the Society of Invertebrate Pathology Annual Meeting in 2004 in Helsinki. This congress gathered around 350 experts to Helsinki, and has been credited as one of the most successful SIP meetings in recent times. In 2012 the International Organization for Biological Control (IOBC-Global) selected Hokkanen as its Honorary Member.

Dr. Econ. Ingeborg Menzler-Hokkanen is a senior postdoctoral project researcher at the Department of Agricultural Sciences, University of Helsinki. After a solid research and publication record within economics, she has focused first on the socioeconomic aspects of plant biotechnology, and then of pest management. She was a workpackage leader in the EU-project MASTER, which investigated the incentives and constraints of farmers to adopt IPM technologies. She also contributed to the EU-project REBECA on the regulation of biopesticides, was a researcher and WP-leader in the EU-FP7 project ‘ForestSpeCs’, and a Task leader in the EU-FP7 project AMIGA. Dr. Menzler-Hokkanen has a MSc-degree in agricultural economics from Georg-August University, Göttingen, Germany; a MSc-degree in agricultural economics  from Cornell University, USA; an Econ. Lic. -degree from the Swedish School of Economics (Helsinki), and a PhD from the Helsinki School of Economics.

She contributes as managing editor to the Springer-Nature journal Arthropod-Plant Interactions, and has managed for 25 years the small consulting firm Aasatek Oy Ltd, which was the first company in Finland to introduce entomopathogenic nematodes for greenhouse growing. Dr. Menzler-Hokkanen is a pioneer in developing entomovectoring techniques for plant protection, and contributed to the development of first commercially used inoculum dispensers for honey bee hives. She was a key member in the Organizing Committee for the large congress of the Society for Invertebrate Pathology, held in 2004 in Helsinki, and is a co-chair, 2020 International Congress of Entomology.
