Fusarium ear rot and fumonisins in maize kernels when comparing a Bt hybrid with its non-Bt isohybrid and under conventional insecticide control of Busseola fusca infestations
(Elsevier, 2018)Maize production in South Africa is negatively affected by Fusarium verticillioides, an endophytic maize pathogen, as well as by Busseola fusca larval damage. Fusarium verticillioides causes ear, stem and root rot, and ... -
Genetic studies of Busseola fusca (Lepidoptera : Noctuidae)
(North-West University (South Africa), 2017)Genetically modified (GM) Bacillus thuringiensis (Bt) Berliner (Bacillales: Bacillaceae) crops have been adopted widely in many countries around the world due to its success in reducing pest damage to crops and the ... -
Insect resistance management in Bt maize: wild host plants of stem borers do not serve as refuges in Africa
(Oxford Univ Press, 2017)Resistance evolution by target pests threatens the sustainability of Bt maize in Africa where insect resistance management (IRM) strategies are faced by unique challenges. The assumptions, on which current IRM strategies ... -
The potential effect of Bt maize on Chrysoperla pudica (Neuroptera: Chrysopidae)
(Oxford Univ Press, 2017)Previous studies into third trophic level exposure of Chrysoperla spp. (Neuroptera: Chrysopidae) to Cry1Ab proteins produced by Bt crops yielded contradicting results. These contradictions were largely ascribed to differences ... -
Resistance status of Busseola fusca (Lepidoptera: Noctuidae) populations to single- and stacked-gene Bt maize in South Africa
(Oxford Univ Press, 2019)Transgenic Bt maize expressing Cry insecticidal δ-endotoxins of Bacillus thuringiensis has been cultivated in South Africa for the control of Busseola fusca since 1998. Busseola fusca is resistant to Cry1Ab Bt maize at ... -
Transcriptome and differentially expressed genes of Busseola fusca (Lepidoptera: Noctuidae) larvae challenged with Cry1Ab toxin
(Elsevier, 2019)Busseola fusca (Fuller) (Lepidoptera: Noctuidae), a major insect pest of maize in sub-Saharan Africa, has de-veloped high levels of non-recessive resistance to Cry1Ab toxin expressed in genetically modified Bt maize.Multiple ...
