“…New Zealand's plantation eucalypt resource for pulp and paper is currently dominated by Eucalyptus nitens , Eucalyptus fastigata and Eucalyptus regnans . The latter two species are nonhosts for T. peregrinus (Saavedra et al , ). Eucalyptus nitens is a potential host for T. peregrinus (Saavedra et al , ) but grows best in cold and higher elevation sites and such plantations occur in the central North Island and Southland.…”

“…It first reached pest status in Sydney, Australia, in 2002, and, to date, it has been reported from 52 different Eucalyptus species or commercial hybrids worldwide (Saavedra et al , ). The most suitable hosts species appear to be Eucalyptus camaldulensis Denhardt, Eucalyptus tereticornis Sm, Eucalyptus viminalis Labill and Eucalyptus nicholii Maiden and Blakely (Noack & Coviella, ; Martínez et al , 2009; Saavedra et al , ). In New Zealand, T. peregrinus is most commonly found infesting E. nicholii .…”

1 Thaumastocoris peregrinus is a sap-feeding insect native to Australia that has become a serious global pest of Eucalyptus species. To date, T. peregrinus has been found in more than 10 countries across Europe, Africa, South America and Oceania. 2 In the present study, we used the climate modelling software climex (Hearne Scientific Software Pty Ltd, Australia) to predict the potential distribution of T. peregrinus globally and in New Zealand. climex parameters were based on experimental data obtained in the present study and from records collated from the insect's native and invasive distribution. 3 The model of the potential native geographical distribution closely agrees with the known distribution of T. peregrinus and predicts potential expansion into more tropical areas of Australia. In New Zealand, the predicted potential distribution of T. peregrinus matches its current distribution and predicts that, if a suitable host is present, the species will be able to establish in most of the North Island and in northern and eastern regions of the South Island. 4 Globally, the model predicts that many of the world's temperate, Mediterranean and subtropical areas are climatically suitable for establishment of T. peregrinus. This predicted distribution closely matches the global distribution of eucalypt plantations, which are essential for the establishment of this pest. 5 climex projections of potential suitability for T. peregrinus reported in the present study may prove useful for risk assessments and for the identification of areas susceptible to invasion by this pest.

ResumoAtualmente um novo conceito de planejamento florestal vem se popularizando, o planejamento florestal espacial. Nele, a unidade de manejo ou talhão passa a ser vista de maneira mais abrangente com análise para seu tamanho, forma e distribuição em relação aos demais. Para este problema, foram elaborados modelos de Programação Linear Inteira (PLI), com uso de restrições do planejamento tradicional, restrições espaciais do tipo URM (Unit Restriction Model) colheita e restrição de adjacência clonal, nova aplicação de URM. Objetivou-se, com este trabalho, criar um modelo de minimização de custo utilizando restrição de adjacência clonal. A intenção desta restrição é reduzir o tamanho de áreas homogêneas, em florestas de eucalipto e, desta forma, diminuir a proliferação de pragas e doenças além de contribuir para a tomada de decisão do gestor florestal. O processamento dos dados foi realizado, nos princípios da PLI e gerou 11 cenários que diferenciaram entre si pela natureza das restrições, espacial e não espacial, bem como restrições volumétricas e limite de área a ser reformada. O volume médio colhido nos cenários sem restrição espacial foi 0,64% maior em relação àqueles com restrições espaciais. A adição de restrição espacial reduziu o valor da função objetivo. Nos cenários, em que houve restrição de área mínima de reforma, houve diferenças significativas nos custos. Para os cenários com 50%, 40% e 30% de área de reforma, houve um aumento de 15%, 11% e 8% no custo final, respectivamente. Os mapas gerados evidenciam, na matriz paisagística, a eficácia da aplicação das restrições espaciais. A aplicação da restrição de adjacên-cia clonal mostrou-se melhor que a URM colheita e seu custo ficou próximo do planejamento tradicional, apenas 0,14% superior, comprovando a viabilidade de sua aplicação no contexto de medida preventiva de proliferação de pragas e doenças, despontando como uma ferramenta potencial para redução de custos com manejo de pragas. Palavras-chave:Planejamento espacial; URM; Matriz paisagística; Pragas florestais. AbstractCurrently a new concept of forest planning has become popular, spatial forest planning. In it, the stand is seen as part of a whole and it is considered its size, shape and distribution in relation to the others. For this problem, we used constraints of traditional planning, spatial constraints of the URM (Unit Restriction Model) type and restrictions of clonal adjacency, a new application of URM in forestry. This study aimed to create a cost minimization model using clonal material adjacent spatial restriction. This was done with the intention of reducing the size of homogenous areas in eucalypt forests and thus hinder the proliferation of pests and diseases, as well as contribute to the decision making of the forest manager. Data processing was carried out with the principles of Integer Linear Programming and generated 11 scenarios differentiated by the nature of the restrictions, spatial and non-spatial, as well volumetric restrictions and limitation of area to be reformed.

“…It has a short life cycle (an average of 35 days) and the female can lay up to 60 eggs during her lifespan (Jacobs and Neser, 2005;Noack and Rose, 2007;Soliman et al, 2012). This high biotic potential enables T. peregrinus to have several generations per year, and to have the potential to spread and rapidly establish into new environments (Nadel et al, 2015;Saavedra et al, 2015).…”

The eucalyptus bronze bug, Thaumastocoris peregrinus, is an exotic pest of eucalyptus crops that has spread worldwide. The objective of this study was to evaluate the toxicity of aqueous plant extracts at 5% of Matricaria chamomilla, Echinodorus grandiflorus, Punica granatum, Maytenus ilicifolia and Origanum majorana on T. peregrinus. For this, choice and no-choice tests were performed. Eucalyptus leaf disks were treated with 5% aqueous extract and two experiments were conducted: (1) the leaf disks were put inside a tube with T. peregrinus adults and their longevity was evaluated. Each repetition was one leaf disk/tube (no-choice test); (2) one leaf disk of each treatment was put inside a Petri dish, and offered to T. peregrinus. Faecal deposits on each leaf disk were quantified (choice test). In addition, high performance liquid chromatography (HPLC) was carried out to verify phenolic compounds present in the plant extracts. All plant extracts reduce the survival of T. peregrinus adults up to nearly 50%. Regarding the choice experiment, T. peregrinus fed with eucalyptus disk leaves containing E. grandiflorus, M. chamomilla and Maytenus ilicifolia extracts produced less faecal deposits when compared wiht the other plant extracts and the control group. In addition, HPLC detected gallic, ferulic, caffeic, coumaric and vanillic acid in the extracts samples. These results suggest that these three plant extracts had a repellent effect on T. peregrinus adults, aside from reducing its survival, and the phenolic compounds may have contributed to these results.
