African armyworm (Spodoptera Exempta) is a serious migratory pest of pasture and grain crops in Africa. Two novel control technologies are described to replace environmentally damaging and expensive synthetic chemical pesticides. The first is a process for local mass-production and formulation of S. exempta nucleopolyhedrovirus (SpexNPV), a naturally occurring biological control agent. The second is the validation of neem extracts, a locally available botanical agent. These approaches have now been adopted as national policy in Tanzania. This technology should be of interest to other African countries where armyworm epidemics are a problem (Kenya, Uganda, Mozambique, South Africa, etc.).
