Busseola fusca (Lepidoptera: Noctuidae) moth and larval behaviour in Bt- and non-Bt maize: an IRM perspective
(North-West University (South Africa), 2020)The African maize stemborer, Busseola fusca (Fuller) (Lepidoptera: Noctuidae) is one of the most damaging pest species of maize in Africa. Genetically modified (GM) Bt maize that expresses insecticidal Cry proteins could ... -
Efficacy of Bt Maize for control of Spodoptera frugiperda (Lepidoptera: Noctuidae) in South Africa
(Oxford Univ Press, 2019)Spodoptera frugiperda (J.E. Smith) is an invasive pest species that threatens maize production by small holder farmers in Africa. Bt maize that express Cry proteins have been used effectively for control of this pest in ... -
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 ... -
Monitoring resistance to Bt maize in field populations of Busseola fusca (Fuller) (Lepidoptera: Noctuidae) from smallholder farms in the Eastern Cape Province of South Africa
(Entomological Society of Southern Africa, 2017)Post-release monitoring of transgenic Bt maize fields for resistant pest populations is an important activity that will contribute to early identification and mitigation of resistance evolution by target pests. An effective ... -
No fitness costs associated with resistance of Busseola fusca (Lepidoptera: Noctuidae) to genetically modified Bt maize
(Elsevier, 2014)A concern regarding planting of Bt crops is that their widespread cultivation could lead to evolution of insect resistance to Bt toxins. In South Africa, the noctuid maize stem borer (Busseola fusca [Fuller]), is resistant ... -
Preference of Bt‐resistant and susceptible Busseola fusca moths and larvae for Bt and non‐Bt maize
(Wiley, 2019)The sustainability of genetically engineered insecticidal Bacillus thuringiensis Berliner (Bt) maize, Zea mays L. (Poaceae), is threatened by the evolution of resistance by target pest species. Several Lepidoptera species ... -
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 ... -
Susceptibility of Spodoptera frugiperda (Lepidoptera : Noctuidae) to Bt maize in South Africa
(North-West University (South Africa)North-West University, 2020)Spodoptera frugiperda, the fall armyworm (FAW), invaded Africa during 2016 and is now considered the number one maize pest in Africa. The destructive feeding habits of FAW larvae threaten maize production in Africa. Bt ... -
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 ...
