Different mango cultivars are commercially grown in South Africa with the most important production areas in Mpumalanga and Limpopo Provinces. The South African mango growers would like to access new export markets, but fruit flies (Ceratitis species) (Diptera: Tephritidae) and the mango seed weevil, Sternochetus mangiferae L. (Coleoptera: Curculionidae) are important quarantine pests. Furthermore, various scales and mealybugs of the superfamily Coccoidea and of the families Coccidae, Diaspididae, Monophlebidae and Pseudococcidae are known to attack mango in South Africa. Therefore a survey was carried out during the 2007/08 season on the cultivars 'Tommy Atkins', 'Kent', 'Sensation' and 'Keitt' to determine which species of scales and mealybugs were present at harvest. This information is important with regard to the entering of new export markets, because some Coccoidea are regarded as quarantine pests. A minimum of 18 orchards per cultivar in different production areas were inspected. In each orchard 10 fruit and 10 leaves from 12 trees were inspected. Various scale and mealybug species were recorded. The mango scale, Aulacaspis tubercularis Newstead (Hemiptera: Diaspididae) was the most abundant species. 'Keitt' had the highest level of infestation on both the leaves and the fruit and 'Tommy Atkins' was least affected.
