Distribution of Mantodea in South Africa and biological studies of selected species
(North-West University (South Africa), 2020)
Despite human fascination with the Mantodea or praying/preying mantids over millennia, very little is known about of their diversity, biology and ecology, especially in South Africa. Praying mantids are not only important ...
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 ...
Comparative diversity of arthropods on conventional and genetically modified Bt soybean plants in field trials in South Africa
(North-West University (South Africa), 2020)
Genetically modified soybean expressing Cry1Ac toxins derived from the soil bacterium Bacillus thuringiensis (Bt), have been approved for experimental cultivation in South Africa. Helicoverpa armigera is the target species ...
Host suitability of poaceous and broad leaf plants for Fall armyworm (Spodoptera frugiperda) (Lepidoptera: Noctuidae)
(North-West University (South Africa), 2020)
Spodoptera frugiperda is native to the Americas but invaded the African continent in 2016, causing damage to maize and sorghum. Reports from literature indicate that larvae of S. frugiperda can feed on 353 different host ...
Biology and ecology of Ceratitis rosa and Ceratitis quilicii (Diptera: Tephritidae) in citrus
(North-West University (South Africa), 2020)
Ceratitis rosa Karsch s. l. (Diptera: Tephritidae), an indigenous pest of commercial fruit including citrus in South Africa, belongs to a complex of cryptic species (Ceratitis FAR). Ceratitis rosa s.l. was recently split ...
Diversity of non-crop plants and arthropods in soybean agro-ecosystems in South Africa
(North-West University (South Africa)North-West University, 2020)
Soybean is widely cultivated in the Grassland Biome of South Africa (>700 000 ha per annum). Yet the possible effects large-scale cultivation of soybean has on biodiversity in adjacent habitat is not fully understood. It ...
Relationship between Spodoptera frugiperda (Lepidoptera: Noctuidae) damage and yield loss in maize
(North-West University (South Africa)North-West University, 2020)
Fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) feeding on maize results in extensive foliar damage if plants are attacked during the pre-flowering stages. Infestation during late plant ...
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 ...
