In March 2002, South African Citrus Thrips (SACT), Scirtothrips aurantii Faure, were detected on ornamental Mother of Millions plants (Bryophyllum species) in a suburb of Brisbane, Australia. The area of infestation was quarantined and plants were destroyed. Recent surveys found SACT widely distributed in southwest Brisbane. The level of infestation suggests that SACT may have been present for several years. Previously, S. aurantii has only been known to occur in Africa and Asia (Yemen).

These thrips are typically found on citrus (especially Citrus sinensis) but have a wide host range of over 50 species that includes mangoes (Mangifera indica), banana (Musa paradisiaca), and tea (Camellia sinensis). This pest is not likely to be transported on traded fruit but could be carried on plants for propagation.
