The Insect Resistant Maize for Africa (IRMA) Project aims at increasing maize production and food security through the development and deployment of insect resistant maize. Bt maize utilizes genes that encode delta-endotoxins; proteins derived from the soil bacterium Bacillus thuringiensis (Bt). Suitable genes have been acquired or synthesized and backcrossed into elite maize germplasm. Clean Bt gene events containing only the gene of interest and no antibiotic or herbicide resistance markers have been developed. maize leaves have been introduced into Kenya, insect bioassays carried out and the effective cry proteins against major maize stem borers identified. Insect resistant maize varieties are being developed using conventional breeding and locally adapted as well as exotic germplasm. To ensure safe dissemination of Bt maize, studies on their impacts on target and non-target arthropods mainly through their characterization and quantification have been done. Insect resistance management strategies are being developed and studies on gene f1ow are under way. Impact studies have revealed factors in the society that will hinder or enhance adop1ion of Bt maize as well as establish baseline data that will form the basis of monitoring and evaluation. Technology transfer and capacity building, creating awareness and communications are important activities in the project. These activities address the various concerns that surround the use of genetically modified organisms. This paper provides a general overview of the IRMA project, presents brief results from various activities and examines how the various concerns about GMOs are addressed within the project activities.Collection: CIMMYT Staff Publications Collection
