Interrelationships between Diglyphus isaea, Phaedrotoma scabriventris and endophytic fungi in the control of Liriomyza leafminers
(2013)
Horticulture is a major foreign exchange earner in Kenya and provides employment to approximately 75% of the population. However, the growth of the horticultural industry is constrained by pests such as the leafminer flies, ...
Migration patterns and survival of Busseola fusca larvae in maize plantings with different ratios of Bt and non–Bt seed
(2014)
The high-dose/refuge strategy is used globally to manage insect resistance development in genetically modified crops with insecticidal properties (Bt crops). The “refuge in a bag” (RIB) strategy is also being considered ...
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 ...
The indirect effect of Cry 1Ab protein expressed in Bt maize, on the biology of Chrysoperla pudica (Neuroptera: Chrysopidae)
(2014)
Genetically modified (GM) maize was developed mainly to control lepidopteran pests such as the maize stem borer (Busseola fusca) (Lepidoptera: Noctuidae). Since the first commercialization of GM crops with insecticidal ...
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 ...
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 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 ...
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, ...
