This paper reviews entomophagy as practised in Africa within the context of food and nutritional security by providing an inventory of the various species of insects that are consumed on the continent and suggests a research for development (R4D) agenda for sustainable utilisation of insects for food and feed. Our survey showed that over 470 species of insects are eaten in Africa. The Central African region remains the most important hotspot of having a culture of entomophagy. The insects mostly eaten in the continent are dominated by the orders Lepidoptera, Orthoptera and Coleoptera. Commonalities were observed across the majority of the insects consumed across Africa, providing opportunities for related R4D activities. An R4D agenda and pathways for using edible insects suggest that socio-economics and marketing studies should address issues of communities’ perceptions, based on their cultural background, income and beliefs. Cost-effective rearing, harvesting and processing technologies are required to prevent depletion and ecological perturbations while ensuring continuous availability of insect-based products. Indigenous reports assert that some edible insects harbour medicinal properties; thus, the need to undertake nutritional and bioactive chemical characterisation of main edible insects along the value chain and to investigate food safety issues such as diseases, allergies, and toxicological and chemical hazards. The use of insects for waste conversion into animal feed and fertiliser requires judicious choice of substrate in view of concerns regarding contaminant loads and pathogens occurrence. Responding to these research needs and opportunities,icipe has recently established an Insects for Food, Feed and Other Uses Programme with well-defined work packages oriented towards attainment of its Vision and Strategy 2013-2020 document, with a strong orientation towards R4D and a focus on activities that lead to adoption and impact on end users, through broad based complementary linkages and partnerships with agriculture and livestock extension services, Food and Agriculture Organization of the United Nations, Consultative Group on International Agricultural Research and advanced research institutes, non-governmental organisations and the private sector.
