Exploiting early herbivory-induced defense traits in Zea species for the management of Chilo partellus in East Africa
(North-West University, 2014)
Maize, a genetically diverse crop, is the third largest cereal crop in the world and the most important staple cereal in sub-Saharan Africa, supplying 50% of the calorie intake in this region. The stemborer Chilo partellus ...
Efficacy of Bacillus thuringiensis spray applications for control of lepidopteran pests
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 ...
Migration patterns and survival of Busseola fusca larvae in maize plantings with different ratios of Bt and non–Bt seed
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 ...
The indirect effect of Cry 1Ab protein expressed in Bt maize, on the biology of Chrysoperla pudica (Neuroptera: Chrysopidae)
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 ...
Arthropod and plant diversity of maize agro–ecosystems in the grassland and savanna biomes of South Africa
Maize (Zea mays L.) is the most important grain crop in the country. Approximately 12 million tons of maize grain is produced annually on approximately 2.5 million ha of land. However, increased farming intensity can lead ...
