Effect of pyrimethamine on gametocytogenesis, exflagellation and asexual growth in southern African isolates of Plasmodium Falciparum.
(1995)Pyrimethamine efficacy was investigated in vitro on the blood asexual stages, the sexual stages and exflagellation in Plasmodium falciparum. Gametocytogenesis was stimulated following the standard methods on five isolates ... -
Epidemiology of human intestinal parasites in Qwa-Qwa, South Africa.
(1995)This study investigated the prevalences and intensity of intestinal parasites and aspects of their epidemiology among children in the Qwa-Qwa region of the eastern Free St~te. Faecal samples of 1180 children differing ... -
Factors affecting millipede, centipede and scorpion diversity in a savanna environment.
(2000)Millipedes, centipedes and scorpions are an important component of the ground-dwelling invertebrate fauna, and may have value as bioindicators of ground-dwelling invertebrate diversity. However, some level of understanding ... -
Field ecology and impact of the seed-feeding beetle Acanthoscelides macrophthalmus, a biological control agent of the invasive tree Leucaena leucocephala, in the KwaZulu-Natal coastal region.
(2014)Introduced for agroforestry, the Mexican tree Leucaena leucocephala (Fabaceae) has become invasive in several tropical and subtropical regions worldwide. In South Africa, the most notable infestations are located in the ... -
The impact of soil water and nitrogen variability on the fitness and performance of Neolema abbreviata Larcordaire (Chrysomelidae) a biological control agent for Tradescantia fluminensis.
(2018)Tradescantia fluminensis Vell. (Commelinaceae) is a plant of Neotropical origin native to the southern parts of Brazil bordering Argentina. In South Africa, it is classified as a category 1B invader species in the National ... -
Impact of the biological control agent Aceria lantanae (Cook) (Acari: Trombidiforms: Eriphyidae) on the invasive weed Lantana camara L. (Verbenaceae) in South Africa.
(2015)This study was conducted to determine the establishment, dispersal, performance and impact of a recently introduced flower-galling mite, Aceria lantanae (Cook) (Acari: Trombiformes: Eriophyidae) on the inflorescence and ... -
An investigation into the robustness of insectary-reared Anopheles Arabiensis for use in the Sterile Insect technique for controlling malaria.
(2018)Human malaria is one of the deadliest vector-borne diseases in the world and is caused by parasites of the genus Plasmodium that are transmitted via mosquitoes of the genus Anopheles. The highest impact of malaria can be ... -
Investigation of the biology and cross-breeding of populations of Pareuchaetes insulata (Lepidoptera : Arctiidae) and the implications for the biological control of Chromolaena odorata (Asteraceae) in South Africa.
(2008)Larvae of Pareuchaetes insulata were released in South Africa for the biological control of the invasive weed Chromolaena odorata. Pareuchaetes insulata has proved to be a difficult agent to establish in the field in South ... -
Malaria vector populations associated with the agricultural development at Mamfene, Northern KwaZulu-Natal, South Africa.
(1995)The irrigation farming methods on the Makhathini Flats are thought to be responsible for recent increase in malaria cases in the Mamfene area of northern KwaZulu-Natal despite ongoing malaria control activities. ... -
Molecular diagnostics and phylogenetics of white grubs in sugarcane.
(2008)Scarabaeid pests in South Africa and especially KwaZulu-Natal are characterised by a very long larval life cycle and short pupal and adult periods. However, it has nearly always been the adults of the species that have ... -
