The cowpea is a high-protein food staple in parts of Africa, particularly in the growing countries of Nigeria, Niger, and Burkina-Fasso. Production is predominantly on small holder farms.  Production is threatened by the pod borer, the larvae of a moth referred to as Maruca, that limits yields and causes farmers to apply large amounts of insecticide to protect their crops.  Dr. TJ Higgins and his team from CSIRO have worked with African scientists to develop a Bt-expressing cowpea.  These lines produce the protein that targets maruca larvae, decreasing insecticide use and producing higher yields in field trials. This innovation is now available to Nigerian farmers and represents a major step forward in sustainability and food security.
