Base-line susceptibility of Busseola fusca for Bt maize in South Africa
(North-West University (South Africa), 2015)
Genetically modified maize that express insecticidal proteins (Bt proteins) have been
commercialized in South Africa for the control of Busseola fusca (Lepidoptera: Noctuidae). Busseola fusca has been reported to be ...
Bt maize and frogs : an investigation into possible adverse effects of Bt toxin exposure to amphibian larvae
(North-West University, 2012)
Genetically modified maize expressing the Bt-protein Cry1Ab (Bt maize) is planted widely in South Africa. Crop residues of Bt maize often end up in aquatic ecosystems where aquatic organisms are exposed to Cry1Ab protein. ...
Effects of Bt crop residues on the development, growth, and reproduction of the freshwater snail, Bulinus tropicus
(North-West University, 2014)
Genetically modified (GM) crops were introduced in South Africa in 1989 and commercially available by 1998. Legislation to control the use of GM crops was only implemented in 1999, with the genetically modified organisms ...
The role of gut microbes on the efficacy of Bt maize against lepidopteran stem borers
(North-West University, 2015)
The evolution of pest resistance to Cry proteins threatens the long-term use of Bt crops. Busseola fusca developed resistance to Bt maize in South Africa but the mechanism of resistance is not well understood. According ...
The response of lepidopteran pests to commercialised Bt maize in South Africa
(North-West University, 2015)
Bt maize expressing Cry1Ab was approved for release in South Africa for control of Busseola fusca (Fuller) (Lepidoptera: Noctuidae) and Chilo partellus (Swinhoe) (Lepidoptera: Crambidae) in 1998. During 2012, a stacked Bt ...
An investigation into the development and status of resistance of Busseola fusca (Lepidoptera : Noctuidae) to Bt maize
(North-West University, 2010)
Based on surface area, South Africa is currently ranked 8th in planting genetically modified (GM) crops in the world. The stem borer, Busseola fusca (Fuller) (Lepidoptera: Noctuidae) is of economic importance throughout ...
Response of selected non-target Lepidoptera, Coleoptera and Diptera species to Cry1Ab protein expressed by genetically modified maize
(North-West University, 2010)
The environmental impacts of genetically modified (GM) crop plants such as Bt (Bacillus thuringiensis) maize have not yet been fully assessed in South Africa. Bt maize designed to express Bt endotoxin for control of Busseola ...
Influence of vermicompost application on rhizospheric microbial communities and Arbuscular mycorrhizal fungal colonisation of BT and non-BT maize in agricultural soil
(North-West University, Potchefstroom Campus, 2018)
Increasing crop production to ensure future food security while reducing environmental pressure on agro-ecosystems requires improved nutrient and water use efficiency. The soil microbial community directly and/or indirectly ...
Busseola fusca (Lepidoptera: Noctuidae) moth and larval behaviour in Bt- and non-Bt maize: an IRM perspective
(North-West University (South Africa), 2020)
The African maize stemborer, Busseola fusca (Fuller) (Lepidoptera: Noctuidae) is one of the most damaging pest species of maize in Africa. Genetically modified (GM) Bt maize that expresses insecticidal Cry proteins could ...
The indirect effect of Bt maize (Cry1Ab) on Cotesia sesamiae (Hymenoptera : Braconidae)
(North-West University (South Africa), 2019)
Busseola fusca (Fuller) (Lepidoptera: Noctuidae), Chilo partellus (Swinhoe) (Lepidoptera: Crambidae) and Sesamia calamistis Hampson (Lepidoptera: Noctuidae) are major pests of maize and sorghum in sub-Saharan Africa. The ...
