The effect of urbanization and agriculture on predacious arthropod diversity in the Highveld grasslands
(2015)
Biodiversity provides vital ecosystem services and more diverse ecosystems are known to be more stable and resilient in the face of disturbance. Predacious arthropods provide a valuable ecosystem service to control pest ...
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 ...
The role of gut microbes on the efficacy of Bt maize against lepidopteran stem borers
(North-West University, 2015)
The evolution of pest resistance to Cry proteins threatens the long-term use of Bt crops. Busseola fusca developed resistance to Bt maize in South Africa but the mechanism of resistance is not well understood. According ...
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 ...
Estimating the impacts of climate change on interactions between different lepidopteran stemborer species
(North-West University, 2015)
The production of cereals, especially maize, which is a staple food in sub-Saharan
Africa, is challenged by pests and diseases. In addition, climate change will exacerbate
the magnitude of these challenges and agriculture ...
The effect of glyphosate and Cry1Ab proteins on the growth and survival of tadpoles of two amphibian species
(2015)
Studies have shown that pesticides have negative effects on non-target organisms. Lately more studies are focusing on amphibians due to their rapid world-wide decline. This study addressed the potential effects of glyphosate ...
