Conservation ecology of Frithia humilis, an endangered succulent of sandstone outcrops in Mpumalanga, South Africa
(North-West University, 2015)
Translocation involves the movement of organisms, by human intervention, from one area to other suitable (receptor) habitats. In a conservation context, translocation can be employed to support species preservation, ...
Dynamics of Napier stunt phytoplasma between the cultivated and wild graminae in East Africa
(North-West University, 2015)
Cultivation of Napier grass, Pennisetum purpureum, the most important livestock crop in East Africa is severely constrained by Napier Grass Stunt (NGS) disease. The disease spreads via an insect vector or vegetative ...
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 ...
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 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 ...
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 ...
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 ...
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, ...
Effect of glyphosate applications on growth responses of various glyphosate tolerant maize hybrids
(North-West University (South Africa), Potchefstroom Campus, 2016)
Glyphosate is a highly effective non-selective, broad-spectrum, post-emergence herbicide used to control a broad spectrum of grasses and broad-leaf weeds. Glyphosate was initially largely used as a burn-down herbicide to ...
