Diversity of gut–microorganisms in Bt–resistant and Bt–susceptible larvae of the maize stem borer (Busseola fusca) (Lepidoptera : Noctuidae)
(North-West University, 2012)
Maize is one of Africa’s main food sources. It is therefore important to protect this crop against pests such as the maize stem borer Busseola fusca. Genetically modified Bacillus thuringiensis (Bt) maize has been shown ...
Status of resistance of Helicoverpa armigera (Lepidoptera: Noctuidae) and Diparopsis castanea (Lepidoptera: Noctuidae) to Bt cotton in South Africa
(North-West University, 2011)
Genetically modified (GM) cotton expressing Cry1Ac proteins was released in South Africa in 1997 for control of the bollworm complex on this crop. No reports of the failure of Bollgard® cotton to control these pests have ...
Efficacy of Bt proteins and the effect of temperature on the development of spiny bollworm in South Africa
(North-West University (South Africa) , Potchefstroom Campus, 2016)
Genetically modified cotton expressing Bacillus thuringiensis (Bt) proteins has been cultivated in South Africa since 1998 for control of the bollworm complex. Spiny bollworms, Earias biplaga (Walker) (Lepidoptera: Noctuidae) ...
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 ...
Community structure of gut microbes in Busseola fusca (Lepidoptera : Noctuidae)
(North-West University, 2015)
Bt-maize is engineered to express insecticidal toxins derived from the bacterium Bacillus thuringiensis and has been shown to be very effective against pests like Busseola fusca.However, resistance of this pest against ...
Susceptibility of Spodoptera frugiperda (Lepidoptera : Noctuidae) to Bt maize in South Africa
(North-West University (South Africa)North-West University, 2020)
Spodoptera frugiperda, the fall armyworm (FAW), invaded Africa during 2016 and is now considered the number one maize pest in Africa. The destructive feeding habits of FAW larvae threaten maize production in Africa. Bt ...
