oa Journal of the Entomological Society of Southern Africa - Orius thripoborus (Anthocoridae), a potential biocontrol agent of Heliothrips haemorrhoidalis and Selenothrips rubrocinctus (Thripidae) on avocado fruits in the eastern Transvaal
The South African avocado industry covers c. 8500 ha and has generated c. R100 million and R30 million p.a. on the export and local markets, respectively, over the last four years (C. J. Partridge, personal communication). Until recently, South African avocados have had few, and relatively unimportant, pests. In 1982 only four insect species causing lesions on avocado fruits were listed, including red-banded thrips Selenothrips rubrocinctus (Giard) and greenhouse thrips Heliothrips haemorrhoidalis (Bouche), which were regarded as not serious enough to warrant insecticidal control (Annecke & Moran, 1982).
