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 ...
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 ...
Migration patterns and survival of Busseola fusca larvae in maize plantings with different ratios of Bt and non–Bt seed
(2014)
The high-dose/refuge strategy is used globally to manage insect resistance development in genetically modified crops with insecticidal properties (Bt crops). The “refuge in a bag” (RIB) strategy is also being considered ...
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 ...
Efficacy of selected insecticides for control of stem borers in maize
(North-West University (South Africa), Potchefstroom Campus, 2016)
Lepidopteran stem borers are important pests of cereal crops in sub-Saharan Africa. The stem borer species Busseola fusca, Chilo partellus and Sesamia calamistis are the most widespread and important stem borer species, ...
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 ...
Response of Chilo partellus (Lepidoptera : Crambidae) to Bt maize in South Africa
(North-West University, 2018)
Maize is an important food resource for humans and their livestock. South Africa is one of the top maize producing countries and also one of the largest producers of genetically modified maize in the world. Maize pests ...
Epigeal arthropod diversity in conservation agriculture and the ecosystem services it provides
(North-West University, 2018)
Conventional agricultural practices, for example, deep ploughing and continuous tillage loosens the soil, disrupts soil structure and leaves the soil surface relatively bare without plant residues to protect it. Soil erosion ...
Busseola fusca and Chilo partellus survival on Bt and stacked-gene maize varieties
(North-West University (South Africa), Potchefstroom Campus, 2016)
Genetically modified Bt maize expressing Cry proteins are used to control lepidopteran pests of maize. Damage caused by these stemborer species Busseola fusca (Lepidoptera: Noctuidae) and Chilo partellus (Lepidoptera: ...
