Aflatoxins in maize : can their occurrence be effectively managed in Africa in the face of climate change and food insecurity?
(MDPI AG, 2022)The dangers of population-level mycotoxin exposure have been well documented. Climate-sensitive aflatoxins (AFs) are important food hazards. The continual effects of climate change are projected to impact primary agricultural ... -
Density dependence and temporal plasticity of competitive interactions during utilisation of resources by a community of lepidopteran stemborer species
(Wiley, 2017)Interactions within and between species sharing the same resources are characterised by competition or facilitation, and can be influenced by factors such as larval numbers and phenotypic plasticity of the interactions. ... -
The effect of Busseola fusca infestation, fungal inoculation and mechanical wounding on Fusarium ear rot development and fumonisin production in maize
(Elsevier, 2017)Fusarium verticillioides and Busseola fusca are among the most significant biotic constraints to maize production in South Africa. In this study, the effect of B. fusca damage and mechanical wounding to maize ears on ... -
The effects of cultivar and prophylactic fungicide spray for leaf diseases on colonisation of maize ears by fumonisin producing Fusarium spp. and fumonisin synthesis in South Africa
(Elsevier, 2016)Fumonisins are mycotoxins produced primarily by Fusarium verticillioides and Fusarium proliferatum on maize. These are secondary, carcinogenic metabolites and have been reported on maize worldwide. Field trials were conducted ... -
Fungal mycoflora associated with Busseola fusca frass in maize plants
(BioOne, 2020)Busseola fusca and Fusarium verticillioides are considered the most important pest and pathogen, respectively, of maize in South Africa. Busseola fusca tunnels into stems and ears of maize plants, whereas F. verticillioides ... -
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 ... -
Nematode pests of maize and other cereal crops
(Springer, 2017)Maize is the most important cereal crop grown in South Africa, followed by wheat and grain sorghum. Yields of grain crops usually vary considerably between years, mainly due to highly variable rainfall. The most widespread ... -
The potential global distribution of Chilo partellus, including consideration of irrigation and cropping patterns
(Springer, 2017)Chilo partellus is a major crop pest in Asia and Africa, and has recently spread to the Mediterranean region. Knowledge of its potential distribution can inform biosecurity policies aimed at limiting its further spread and ... -
Telenomus remus, a candidate parasitoid for the biological control of Spodoptera frugiperda in Africa, is already present on the continent
(MDPI, 2019)The fall armyworm, Spodoptera frugiperda, a moth originating from tropical and subtropical America, has recently become a serious pest of cereals in sub-Saharan Africa. Biological control offers an economically and ... -
The use of mass trapping to suppress population numbers of Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae) in small-scale farmer granaries in Mozambique
(ESSA, 2018)This study evaluated the potential of mass trapping to reduce Prostephanus truncatus population numbers in granaries and hence its possible utilisation as pest management tool. Universal moth traps (Uni-traps) were used ...
