Details of this species in South Africa
Source: Tribe 2005
Species Notes for this Location:
After its introduction, Gonipterus scutellatus caused the defoliation of eucalyptus plantations across South Africa in the early 1900's. Eucalypt plantations are now populated by species more resistant to G. scutellatus, such as Eucalyptus grandis.
Management Notes for this Location:
Anaphes nitens, an egg parasitoid, was introduced to South Africa in 1926 as a biocontrol agent for G. scutellatus. A. nitens is successful in controlling G. scutellatus in all areas except for those at high elevation with cold temperatures. It was found that A. nitens was more successful during spring in winter rainfall areas. Parasitism rates of up to 96% have been recorded (Cape Town).
