Prof. Zeyaur Khan
  • Principal Scientist and Programme Leader

Prof. Zeyaur R. Khan is a Principal Scientist at icipe. He has dedicated his 30 year career as an international agricultural scientist to advancing the science and practice of agriculture by studying and applying chemical ecology, behavior, plant-plant and insect-plant interactions to improve farm productivity to combat poverty and food insecurity in Africa. He is responsible for the discovery and wide scale implementation of a pro-poor scientific innovation for enhancing food security and environmental sustainability in Africa. This was achieved through the biologically-based IPM technology called ‘Push-Pull’ (www.push-pull.net), developed for small-holder cereal-livestock African farmers. Prof. Khan’s work is a wonderful example demonstrating that creativity and innovation in science can provide practical solutions for the real problems of thousands of small-holder poor farmers and promote their food security and sustainable livelihoods. Prof. Khan obtained his Ph.D. from Indian Agricultural Research Institute, New Delhi in 1980. Before joining icipe, he worked with International Rice Research Institute (1983-1991), University of Wisconsin, Madison (1985-1986) and Kansas State University, Manhattan (1991-1993). Prof. Khan also holds a position of Visiting Professor at Cornell University. Prof. Khan is Fellow of Entomological Society of America and Fellow of Royal Entomological Society, London. In 2009 Prof. Khan was awarded the International IPM excellence award, a plenary speaker at during XXIII International Congress of Entomology in 2008 and the 2010 winner of the Nan-Yao Su Award for Innovation and Creativity in Entomology. He has authored/co-authored over 100 scientific papers in referred journals, over 10 book chapters, five books and several booklets and brochures.

Dr. Charles Midega, a Marquis Who’s Who in the World biographee, is a senior research scientist at icipe. He holds an MSc (2002) and PhD (2005) in Agricultural Entomology from Kenyatta University (Kenya), and two postdoctoral fellowships, from icipe (Kenya) and Kyushu University (Japan). He is directly involved in implementation of the Push-Pull technology in East Africa while adapting it to different agro-ecologies, cereal systems and farmer profiles. He is also involved in the chemical ecology research on plant to plant communication and plant-insect interactions and their exploitation for pest management in cereal and cotton production systems. He evaluates the technology’s impacts on ecological integrity of the agro-ecosystems, specifically its impacts on pests’ generalist and specialist natural enemies, as well as above and below ground arthropod diversity. He has extensive experience on biostatistics as well as development of IPM approaches, biodiversity evaluation and sustainable exploitation in different ecosystems, tritrophic interactions in both cropping and forest systems, and chemical ecology, having been involved in similar work in Kenya, South Africa and Japan. He has authored/co-authored over 40 scientific papers in refereed journals, book chapters, books and educational materials in these fields.

Dr. Amanuel Tamiru
  • Research Scientist

Dr. Amanuel Tamiru is a scientist at icipe's ‘Push-Pull’ Programme currently working on smart cereals project. He is interested in understanding the underlying mechanisms of insect–plant and plant-plant interactions, above-below ground, with the aim of developing innovative, ecologically sound and affordable solutions to manage crop pests that threaten food security.He conducts cutting-edge research on plant signaling and insect-plant ecology where he employs latest techniques in behavioral and chemical ecology and molecular biology. He is involved in collaborative research with scientists around the world including the Rothamsted Research (UK), Martin Luther University of Halle-Wittenberg (Germany), Cornell University (USA), ICRISAT and CIMMYT. Dr. Tamiru is recipient of several highly competitive awards including the prestigious Rothamsted International Award, UK (2010) and German Academic Exchange Service (DAAD) Award, Germany (2011) and icipe's Governing Council Award for Best Published Science Paper (2011). He has authored and co-authored over 15 scientific publications including in high impact journals such as ‘Ecology Letters’. Previously, Dr. Tamiru worked as an associate researcher in Entomology at Ethiopian Institute of Agricultural Research (EIAR) where he was actively engaged in designing and executing various pre-and post harvest crop protection researches aimed at integrated management of major crop pests.
