摘要
Ethnopharmacological relevance: The aim of the study was to document plants traditionally used to repel mosquitoes in the uMkhanyakude district, KwaZulu-Natal, South Africa. The specific objectives of the study were to: (1) identify plant species and their parts being used; (2) determine the condition of plant material used and the method of application. Materials and methods: Data was collected from 60 respondents in five villages in the district using standardised and pre-tested questionnaires. Results: Thirteen plant species are used in the study area to repel mosquitoes. These species belong to 11 genera from 9 families. Meliaceae and Anacardiaceae were the most represented families with two species each. The most frequently recorded species were Lippia javanica (91.67%), followed by Aloe ferox (11.67%), Sclerocarya birrea (5%), Melia azedarach (3%), Balanite maughamii (3%) and Mangifera indica (3%). Leaves were the most (38%) common plant part used. The majority (82%) of the plant parts were used in a dry state. Burning of plant materials to make smoke was the most (92%) common method of application. Nine plant species, namely: A. ferox, Calausena anista, Croton menyharthii, S. birrea, B. maughamii, Olax dissitiflora, Trichilia emetic, M. indica, and Atalaya alata are documented for the first time as mosquito repellents. Conclusion: This documentation provides the basis for further studies in developing new, effective, safe and affordable plant-derived mosquito repellents especially for Africa where malaria is highly prevalent. The study also plays a part in documenting and conserving traditional knowledge of mosquito repellent plants for future use.
