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 ... -
Basis of host recognition by the larval endoparasitoids : Cotesia sesamiae Cameron and Cotesia flavipes (Cameron) (Hymenoptera : Braconidae)
(North-West University, 2009)Host recognition behaviour of two braconid larval parasitoids Cotesia sesamiae and Cotesia flavipes was studied using suitable stemborer hosts [i.e. Busseola fusca for C. sesamiae, and Chilo partellus for C. flavipes] and ... -
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: ... -
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 ... -
Comparative phenology of Lepidoptera on genetically modified BT- and non-BT maize
(North-West University, 2006)The maize stem borers, Busseola fusca (Fuller) (Lepidoptera: Noctuidae) and Chilo partellus (Swinhoe) (Lepidoptera: Pyralidae) are economically important pests of maize in South Africa. Genetically modified Bt maize ... -
Density dependence and temporal plasticity of competitive interactions during utilisation of resources by a community of lepidopteran stemborer species
(Wiley, 2017)Interactions within and between species sharing the same resources are characterised by competition or facilitation, and can be influenced by factors such as larval numbers and phenotypic plasticity of the interactions. ... -
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 ... -
Ecological genetics and host range expansion by Busseola fusca (Lepidoptera: Noctuidae)
(Oxford Univ Press, 2015)The host plant range of pests can have important consequences for its evolution, and plays a critical role in the emergence and spread of a new pest outbreak. This study addresses the ecological genetics of the indigenous ... -
Ecology of maize stemborers in irrigated subsistence farming systems in the Limpopo Province
(North-West University, 2006)Stemborer ecology in South Africa has been studied well but largely in maize in commercial monoculture production systems. Stemborers are important pests of maize in resource-poor farming systems at the Tshiombo irrigation ... -
The effect of Busseola fusca infestation, fungal inoculation and mechanical wounding on Fusarium ear rot development and fumonisin production in maize
(Elsevier, 2017)Fusarium verticillioides and Busseola fusca are among the most significant biotic constraints to maize production in South Africa. In this study, the effect of B. fusca damage and mechanical wounding to maize ears on ...
