The story of Prostephanus truncatus in Africa is described from its original outbreak in Tanzania in the late 1970s to the present day. Information is given on the differing control methods put in place by infested countries and how co-ordination of local programmes and inputs from technical assistance agencies was approached by an agencies. The influence of changes in development thinking on the management of storage pests is considered. The current status of P. truncatus is addressed, inlcuding its impact on the international maize trade, particularly that provided for famine relief. The introduction of Teretrius nigrescens as a biological control agent is described. We also provide some milestones in efforts to manage the pest, describe the effectiveness of pest management in terms of cost benefit and suggest some new avenues that may lead to a sustainable reductioning in P. truncatus in Africa. |
