Research Interest

Broadly varied research interests in the areas of integrated pest management and biological control of stored product insect pests. Specifically my research interests are centered on investigating the biology, behaviour, and population dynamics of stored-product arthropod pests and their natural enemies and to use the information acquired to optimize pest management strategies. Dr. Adarkwah is also interested in applying biology and as well as physical control in agricultural crop production and pest management in a manner that is consistent with environmental protection, something that will be increasingly important especially in developing countries as well as Europe. Dr. Adarkwah’s research also addresses important postharvest issues in the field of agricultural and sustainable food development that can have positive impact on food security and agricultural economies of developing countries in particular.

Biography

Dr. rer. agr. Charles Yaw Adarkwah became the second Dean and the first Head of Department of Horticulture and Crop Production of the School of Agriculture Technology (SOAT) of the University of Energy and Natural Resources, Dormaa-Ahenkro Campus. Dr. Adarkwah has previously been involved in teaching, research and extension for more than 18 years. He worked at the Ghana Cocoa Research Institute, Akim Tafo, Ghana, Leibniz-Institute of Vegetable & Ornamental Crops, Großbeeren, Germany, Humboldt Universität zu Berlin, Germany, Morden Research and Development Centre for the Agriculture and Agri-Food Canada, Winnipeg-Manitoba, Canada, Central Science laboratory in York, York, United Kingdom and the Julius Kühn-Institut, Bundesforschungsinstitut für Kulturpflanzen/Federal Research Centre for Cultivated Plants (JKI) Institute for Ecological Chemistry, Plant Analysis and Stored Product Protection. He joined the University of Energy and Natural Resources from the University for Development Studies, Tamale Ghana where he served as a Senior Lecturer of the Faculty of Agriculture, Department of Agronomy. He also previously served as visiting Lecturer, Research Scientist and Head of Stored Product Protection Section of the Faculty of Life Sciences, Division Urban Plant Ecophysiology, Humboldt-Universität zu Berlin, Berlin, Germany. He has led and participated in international research, teaching and administrative activities across Europe and North America. He has over 40 scientific publications in International peer-reviewed Journals and conference proceedings.

Dr. Adarkwah is a fellow of the Entomological Society of America, the Deutsche Phytomedizinische Gesellschaft e.V. and Member Ghana Institute of Biologists. Dr. Adarkwah has won many Research Awards from Deutscher Akademischer Austauschdienst – DAAD (German Academic Exchange Service), Federal Ministry of Education and Research – BMBF, International Migration and Development – CIM, Rosa Luxemburg Foundation, Schweisfurth Foundation, Katholische Studentengemeinde all from Germany and many more.

Dr. Adarkwah  Ph.D. in Agricultural Sciences and M.Sc. in International Agricultural Sciences, both from the Humboldt Universität zu Berlin, Berlin, Germany. He obtained his BSc degree honours in General Agricultural Sciences from the School of Agriculture, University of Cape Coast, Cape Coast, Ghana. Born in Koforidua in the New Juaben Municipality of the Eastern Region of Ghana. Dr. Adarkwah had his early education at the Presbyterian Junior High School. He then continued at the Koforidua Senior High Secondary School before proceeding to the University of Cape Coast, Cape Coast Ghana for his undergraduate degree. Whiles a student he worked at the Cocoa Research Institute of Ghana, CRIG-Tafo and researched into the effect of days after harvesting pod (pod-age) and the depth of sowing on germination and initial seedling development of cocoa.

Immediately after his first degree Dr. Adarkwah won the DAAD and the International Association of Exchange of Students for Technical Experience (IAESTE) scholarship and worked at the Leibniz-Institute of Vegetable & Ornamental Crops, Großbeeren, Germany where he investigated the influence of different plant nutrient strategies on tomato and nutrient uptake patterns in the greenhouse. Dr. Adarkwah’s has ability for scientific leadership in different academic settings and an unusual drive towards discovering and initiating new knowledge and skills. He enrolled into the M.Sc. program in the International Agricultural Sciences at the Humboldt-Universität zu Berlin, Germany. He successfully carried out his master’s thesis at the Modern Research Centre for Agriculture and Agri-Food Canada, the Julius Kühn-Institut, Berlin, Germany. Dr Adarkwah investigated the mechanism of resistance towards diatomaceous earth of three stored product beetles.

In the Ph.D. thesis Dr. Adarkwah focused on the biological control of some stored product insect pests by use of parasitic wasps partially in combination with neem. Dr. Adarkwah also investigated the ecology of various parasitoid wasp species that attack stored grain beetles. He applied the wasps for control of the pest insects. He also integrated the application of biopesticides like neem oil and parasitoid wasps for insect control, Dean Adarkwah has adequate knowledge and experience in insect science (taxonomy, biology, behaviour and physiology) as well as in general zoology, molecular biology, ecology, microbiology, evolution and statistics. These facts clearly lend credence to the Dr. Adarkwah’s scientific capabilities and put him on a strong platform to succeed in any related research involving naturally occurring products for integrated pest management.

Dr. Adarkwah as an astute scholar has travelled extensively as visiting scholar. He has conducted research and participated in numerous national and international scientific conferences in Africa, Europe and Canada. As a distinguished Researcher, he has published widely and has over 40 publications in internationally reputable refereed journals, books and several technical reports and conference proceedings.

Dr. Adarkwah has been a visiting Lecturer of several Universities in Europe and North America. He has won several academic awards including the best presenter of the postgraduate forum of the Royal Entomological Society of England. Dr. Adarkwah has so far successfully supervised over 40 undergraduate dissertations, 5 MPhil and 3 Ph.D. theses. He reviews scientific manuscripts for publication in over 10 scholarly journals worldwide. He is a member of many scientific and professional bodies. Since 2010, he has taught several courses in insect biology, agricultural entomology, insect ecology and control, stored product entomology, vertebrate pest management, post-harvest technology, pesticide science as well as plantation and industrial crop production at the diploma, undergraduate and graduate levels. Dr. Adarkwah is a confirmed Presbyterian and married to Dr. Vivian Asante and they are blessed with three children, Crystal, Jayson and Mary. Dr. Adarkwah has superb interpersonal skills, and is amiable, affable and a great team player. He is emotionally and physically very fit, and likes Christian fellowship, reading and travelling. He enjoys the goodwill of God and persons.
