A concern regarding planting of Bt crops is that their widespread cultivation could lead to evolution of insect resistance to Bt toxins. In South Africa, the noctuid maize stem borer (Busseola fusca [Fuller]), is resistant to Bt maize (Zea mays L.; M

Based on surface area, South Africa is currently ranked the eighth in planting genetically modified (GM) crops in the world. Bt maize (MON810) has been grown to control lepidopterous stem borers in South Africa since its first release during 1998. Th

The lepidopteran stemborers Busseola fusca (Fuller) (Lepidoptera: Noctuidae), Sesamia calamistis (Hampson) (Lepidoptera: Noctuidae), and Chilo partellus (Swinhoe) (Lepidoptera: Crambidae) are effectively controlled by Bt maize that expresses the Cry1

Research that focused on maize production on the central Highveld of South Africa was traditionally, since the early twentieth century, dealt with by the Department of Agriculture at Potchefstroom. During the 1970s the Highveld Region at Potchefstroo

Bt maize has been grown at the Vaalharts irrigation scheme in South Africa since its first release during 1998. Interest in Bt maize refuge compliance, pest incidence and production practices at Vaalharts were recently stimulated by the first report

Maize, expressing Cry1Ab insecticidal proteins produced by the bacterium Bacillus thuringiensis (Bt), was introduced for control of Busseola fusca (Fuller) (Lepidoptera: Noctuidae) and Chilo partellus (Swinhoe) (Lepidoptera: Crambidae) in South Afric

Reports of severe damage caused by the African stem borer, Busseola fusca (Fuller) to Mon810-transgenic maize (Bt) prompted a study in which the survival of progenies of diapause larvae collected from both a Bt and non-Bt planting were compared when

Stem borer resistant inbred lines Mp704 and Mp706 of Mississippi origin were used as donor parents in a recurrent selection programme, to develop locally adapted germplasm with improved resistance to the stalk borer Busseola fusca. The segregating pr

The objective of this study was to evaluate the adaptation of 10 maize genotypes across five locations and three years in Ethiopia. Grain yield of 10 maize genotypes, tested in a randomised block design with four replications across the named environ

The inheritance of resistance to the African stem borer, Busseola fusca, in maize was investigated by means of line x tester analyses in the F1 to F4 generations of crosses between 18 susceptible inbred lines and two resistant testers of common genet
