Bronze Bugs on the move

Scion is the leading provider of forest-related knowledge in New Zealand
Formerly known as the Forest Research Institute, Scion has been a leader in research relating to forest health for over 50 years. The Rotorua-based Crown Research Institute continues to provide science that will protect all forests from damage caused by insect pests, pathogens and weeds. The information presented below arises from these research activities.

From Forest Health News 276, October 2017.

Bronzing of Eucalyptus sp. foliage caused by bronze bug. 

Bronze bug (Thaumastocoris peregrinus), the sap-sucking Eucalyptus spp. pest is on the move. Scion entomologist Toni Withers has now recorded bronze bug in Tauranga, extending its range in the North Island significantly east from its previous records in Cambridge (apart from an isolated population in Napier). Bronze bug was first recorded in New Zealand in March 2012 and has been dispersing relatively slowly in New Zealand (see FH News 233 for more details). It causes the characteristic ‘bronzing’ of all or parts of tree foliage it is infesting. Usually this symptom is most obvious in the autumn and winter but the FH news editors are interested in any finds of this species north of Auckland and south of Cambridge.
