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. Click here for more information on the release (in Portuguese) at the IPEF website. (A Google Translate version of this information in English can be found here). 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). For its current known worldwide distribution click here.
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
The first shipments of Thaumastocoris peregrinus eggs under this project left Australia on 12 September and have already been producing egg parasitoids in Quarantine in both countries. Collections were made by Dr Ann Noack in the Olympic Park area of Sydney, site of the 2000 Sydney Olympics. Further shipments are planned over the coming months when partners and associates are able to accept them.
