Cirad - icipe: ON-GOING COLLABORATIONS Physical control of
Cirad - icipe: ON-GOING COLLABORATIONS May 5 - 2015 Physical control of insect pests in the horticultural crops The global objective is to reduce the use of chemical pesticides in horticultural crops in Sub Saharan Africa. The aim is first to develop insect proof nets with smallholder growers for the protection of horticultural crops to reduce pesticide use and, secondly, to combine this technology with biological control methods in a push pull strategy. Research on the biological efficacy of the nets on insects (as a visual and physical barrier), on their combination with other biological control methods (i.e. repellent companion plant), on their effect on various crops (micro-climate, water consumption, plant physiology, diseases, yield and quality of production), on their management, and on the socio-economic aspects linked to their adoption (labour demand, cost/profit analysis), or promotion (impact on the environmental and public health). Common projects BionetAgro (Hort CRSP USAID, 2012-2015), one PhD student funded by Cirad on red spider mite behavior and interaction with predatory mites Trips IPM (African Union, 2012-2015), one PhD student funded by AgTrain EU on repellent plants against thrips NatProtect (Fondation Mutavie, 2011-2014), one PhD student funded by the project on repellent plants against whiteflies Other partners: Institut National de Recherches Agricoles du Bénin and Université Abomey-Calavi (Bénin), IRD UMR Mivegec, CNRS UMR Cefe and USDA-Montpellier (France), GTZ (Germany), KALRO, Real IPM and Egerton University (Kenya), AtoZ (Tanzania), Michigan State University (USA) Significant publications 2015 E.

Common projects CHIESA (Finland, 2011-2015), Climate Change Impact on Ecosystem pest management and pollination AFS4Food (EU, 2012-2015), Coffee Pest and Disease Impact and Management in the Kenyan Agroforestry Context SAFSE (AIRD, 2013-2015), Shade management and its impact on the natural enemies of the coffee berry borer (Hypothenemus hampei): towards shading recommendations for the biological control of coffee pests in agroforestry systems in Kenya.
