This just-published paper provides more information on the occurrence and distribution of Thaumastocoris peregrinus in Portugal. On this occasion it also appears to have arrived together with a predator apparently picked up in South America!
Garcia A, Figueiredo E, Valente C, Monserrat VJ, Branco M (2013) First record of Thaumastocoris peregrinus in Portugal and of the neotropical predator Hemerobius bolivari in Europe. Bulletin of Insectology. 66(2):251-256
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. 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.
