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 ... -
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 ... -
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 temperature on the development and reproduction of Busseola fusca (Lepidoptera: Noctuidae)
(North-West University, 2015)Busseola fusca is an indigenous lepidopteran pest species in tropical Africa, attacking several grain crops. Crop loss caused by this pest can be as high as 100% depending on conditions. Despite it being a major pest in ... -
The effect of water volume and dosage rate on the efficacy of Break-Thru S240 for stem borer control
(North-West University, 2008)The two most prominent stem borer species responsible for damage to maize in South Africa are the African maize stem borer, Busseola fusca (Fuller) (Lepidoptera: Noctuidae) and spotted stem borer, Chilo partellus (Swinhoe) ... -
Efficacy of Bacillus thuringiensis spray applications for control of lepidopteran pests
(2014)Organic insecticides play a big role in reducing the usage of chemical insecticides and their negative impact on the environment. Bacillus thuringiensis (Bt) spays are the only tool that organic farmers are allowed to use ...
