The bronze bug, Thaumastocoris peregrinus, has now been reported as established in Portugal for the first time. This follows the first report of its detection in Europe from Italy in 2011 and in New Zealand in 2012.
Update (10 June 2013) provided by Dr Carlos Valente, RAIZ:
By the end of 2012, T. peregrinus had been detected only in the Lisbon region, mainly on E. camaldulensis. During a survey at an arboretum in the Technical University of Lisbon, T. peregrinus was also found on other Eucalyptus species, including E. globulus. However, the insect has not yet been detected in commercial plantations. In June 2013 further surveys will be conducted to determine its distribution and impact.
The red gum lerp psyllid Glycaspis brimblecombei has now extended its range into southern Africa with the recent detection of this insect in Pretoria, South Africa. More information can found about this discovery here, here and here.
The Tree Protection Cooperative Program at FABI has now produced a pest alert leaflet page which can be seen here.
There is also now a BiCEP page for G. brimblecombei which will be updated with references and more images soon.
According to BiCEP collaborator Prof Carlos Wilcken, four field releases of Cleruchoides noackae have now been made in Brazil, three in the State of Minas Gerais (MG), where the most serious infestations have been seen this year, and one in Sao Paulo (SP) State.
Successful recovery of parasitoids from the field has now been recorded at 3 of the four release sites (2 in MG and 1 in SP) with the fourth site yet to be evaluated. This is very encouraging news since the releases were made under climatic conditions (high temperatures and low humidity) that are not considered to be favourable to this egg parasitoid. Further evaluations are being made during October.
The first field release in Brazil of the Thaumastocoris peregrinus egg parasitoid Cleruchoides noackae was made in Minas Gerais state in Brazil on August 6.

This is now the second release of C. noackae outside of Australia, following the release by Chile in June 2010. (English translation here)
Congratulations to Prof Carlos Wilcken and his team at IPEF and UNESP and Dr Luiz Alexandre Nogueira de Sá and his team at the EMBRAPA Costa Lima Quarantine Laboratory for this great achievement. This is the result of close collaboration over a number of years between Australia and Brazil, illustrating the benefits of a coordinated response to this key eucalypt plantation pest.
Updates will be posted on establishment and impact of C. noackae on T. peregrinus in Brazil as they come to hand.
The Bronze Bug, Thaumastocoris peregrinus, continues to expand its global range, with it now being established in Italy as of September 2011 (as mentioned by Annie in the previous post) and with a more recent detection on street trees in Auckland, New Zealand (March 2012).

More information on the establishment of T. peregrinus in Italy can be found here in a paper by Laudonia & Sasso in the Bulletin of Insectology, Vol 65 (1): 89-93, 2012, and in this European and Mediterranean Plant Protection Organization (EPPO) publication by the same authors.
Given the speed with which T. peregrinus has spread since the first detections in southern Africa and South America, it is likely it will also spread quickly in Europe following this initial establishment in Italy. This is of particular concern for plantation growers of Eucalyptus globulus in countries such as Portugal, Spain and France since this species is a known host of T. peregrinus in Australia.
The detection of T. peregrinus in New Zealand is reported in Forest Health News No. 226, June 2012 and in Surveillance magazine Vol 39 (2) pp 43-46. According to the latter publication:
In New Zealand this insect may not be eradicable as it appears to be well established, and there do not appear to be any effective eradication methods. Potential next steps are being considered
