Plant and arthropod diversity of maize agro–ecosystems in the Highveld and Lowveld regions of South Africa
(North-West University, 2011)
Surveys of plant and selected insect species was conducted in Highveld and Lowveld
agro–ecosystems of four provinces of South Africa, namely North–West, Mpumalanga,
KwaZulu–Natal and Limpopo. The objectives of the study ...
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 ...
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) ...
Implementation of the push–pull strategy for Eldana saccharina control on sugarcane in KwaZulu–Natal, South Africa
(North-West University, 2013)
The aim of the research presented in this dissertation was to further the implementation of push-pull for control of Eldana saccharina on sugarcane in the Midlands North region, KwaZulu-Natal, South Africa. Eldana saccharina, ...
Pest risk assessment for regulatory control of Bactrocera invadens (Diptera : Tephritidae) in the Musina area (Limpopo Province)
(North-West University, 2013)
Fruit flies (Tephritidae) can enter and establish in new territories due to the movement of fruit from one area to another through trade or tourism, which can negatively impact on fruit production and market access. An ...
Bt maize and frogs : an investigation into possible adverse effects of Bt toxin exposure to amphibian larvae
(North-West University, 2012)
Genetically modified maize expressing the Bt-protein Cry1Ab (Bt maize) is planted widely in South Africa. Crop residues of Bt maize often end up in aquatic ecosystems where aquatic organisms are exposed to Cry1Ab protein. ...
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 ...
The effect of a cabbage-carrot intercropping system on the incidence of cabbage pests
(North-West University, 2007)
Cruciferous crops comprise one of the major crop divisions and contribute
significantly to global crop production. Insect pests associated with cruciferous crops have the potential to destroy harvests. The diamondback ...
Efficacy of Bt proteins and the effect of temperature on the development of spiny bollworm in South Africa
(North-West University (South Africa) , Potchefstroom Campus, 2016)
Genetically modified cotton expressing Bacillus thuringiensis (Bt) proteins has been cultivated in South Africa since 1998 for control of the bollworm complex. Spiny bollworms, Earias biplaga (Walker) (Lepidoptera: Noctuidae) ...
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 ...
