| A busca por informações para o controle de Thaumastocoris peregrinus (Hemiptera: Thaumastocoridae) em Eucalyptus concentra-se no uso de técnicas de controle biológico, entre elas, o uso de fungos entomopatogênicos. Assim, o objetivo deste trabalho, foi avaliar a patogenicidade de isolados de Beauveria bassiana e Isaria sp. sobre Thaumastocoris peregrinus em condições de laboratório. Para isto, foram testados quatro isolados de Beauveria bassiana e um isolado de Isaria sp. na concentração de 1,0 × 108 conídios.mL-1. A solução foi aplicada sobre folhas de Eucalyptus camaldulensis, fornecidas como substrato de alimentação aos insetos, e mantidas em frascos de vidro vedados com filme plástico em câmara climatizada (26 ± 2°C, 14 h de fotofase e U.R. de 70 ±... |

| Estratégias eficientes para controlar o percevejo bronzeado Thaumastocoris peregrinus Carpintero e Dellapé (Hemiptera: Thaumastocoridae) não estão disponíveis, mas Cleruchoides noackae Lin e Huber (Hymenoptera: Mymaridae) parasita ovos desta praga. O parasitismo e o número de parasitoides emergidos por ovo de T. peregrinus foram avaliados em laboratório e em ovos desta praga coletados em campo em uma área de, aproximadamente, 2 hectares, 1 ano após a liberação de C. noackae para verificar o estabelecimento desse parasitoide em plantações de eucalipto, em Minas Gerais, Brasil. A taxa de emergência de C. noackae, de ovos parasitados em laboratório e campo, foi de 53% e 52%, respectivamente. Este inimigo natural foi registrado em todos os dez pontos de... |

| ABSTRACT Thaumastocoris peregrinus (Hemiptera, Thaumastocoridae) is a phytophagous pest of eucalyptus plantations. It was introduced in Brazil in 2008, and expanded rapidly due to its adaptive capacity to different climatic conditions. Eucalyptus has been planted in the Brazilian Amazon since the 1980s, being used in silvopastoral systems and for cellulose production. Since its introduction in the southernmost Brazilian state of Rio Grande do Sul, T. peregrinus has expanded its geographical distribution to 117 municipalities in states in the south (Rio Grande do Sul, Santa Catarina and Paraná), southeast (São Paulo, Espirito Santo, Rio de Janeiro and Minas Gerais), mid-west (Mato Grosso do Sul and Goiás) and northeast (Sergipe) of the country. Here we... |

| The bronze bug, Thaumastocoris peregrinus, an Australian native insect, has become a nearly worldwide invasive pest in the last 16 years and has been causing signifcant damage to eucalypts (Myrtaceae), including Eucalyptus spp. and Corymbia spp. Its rapid expansion leads to new questions about pathways and routes that T. peregrinus used to invade other continents and countries. We used mtDNA to characterize specimens of T. peregrinus collected from 10 countries where this species has become established, including six recently invaded countries: Chile, Israel, Mexico, Paraguay, Portugal, and the United States of America. We then combined our mtDNA data with previous data available from South Africa, Australia, and Europe to construct a world mtDNA network... |

| Thaumastocoris peregrinus has become a major pest in eucalyptus. The most promising control method is the use of the parasitoid, Cleruchoides noackae, but little is known about its biology. Thus, the aim of this study was to investigate the oviposition behaviour of C. noackae in T. peregrinus eggs laid on strips of paper towel in the laboratory. 12 copulated females were placed in a plastic petri dish containing five T. peregrinus eggs and their behaviour was observed for 30 min/female. Several behavioural events were performed: searching for the host, host evaluation, insertion of the ovipositor, internal recognition and oviposition. Time elapsed between the insertion of the ovipositor and its removal varied from two to ten minutes. Learning more about C.... |

| Cleruchoides noackae (Hymenoptera: Mymaridae), native to Australia, is the most promising biological control agent for Thaumastocoris peregrinus (Hemiptera: Thaumastocoridae), an exotic Eucalyptus spp. pest in Brazil. The aim of this study was to determine the courtship behaviour, mating and oviposition of unmated or mated C. noackae females parasitizing T. peregrinus eggs utilizing the same rearing system used in biological control programmes in Brazil. The mating behaviour of eleven C. noackae unmated couples was observed and the time taken for males and females to find each other in polystyrene vials and the duration and number of copulations were recorded. Ten unmated or mated females were placed individually in vials with 10 T. peregrinus eggs each,... |

| Plants of the genus Eucalyptus, cultivated in many countries, have great importance for the world economy. In Brazil, this culture occupies a total of 5.7 million hectares, but native and exotic insect pests can reduce its productivity. Thaumastocoris peregrinus Carpintero & Dellapé (Hemiptera: Thaumastocoridae), an exotic Australian pest, damages Eucalyptus plants. Biological control using the egg parasitoid Cleruchoides noackae Lin & Huber (Hymenoptera: Mymaridae), Heteroptera predators and entomopathogenic fungi, such as Beauveria bassiana and Metarhizium anisopliae, have potential for managing T. peregrinus. Chemical insecticides, including bifenthrin and acetamiprid+bifenthrin, also control this insect. The compatibility of chemical and... |

| ABSTRACT: Native of Australia, Thaumastocoris peregrinus (Eucalyptus bronze bug) is a Eucalyptus insect pest which was firstly detected in Brazil in June 2008. Some studies have shown favorable areas for T. peregrinus population outbreaks in Brazil, based on georeferenced-crossing information using geographical information system (GIS). Despite that, it is crucial to both enhance the precision of methods used on georeferenced crossings and update information, in order to enable greater precision toward the identification of propitious areas for the occurrence of the insect. The objective of this study was to identify areas with favorable conditions to occurrence of Thaumastocoris peregrinus in Brazil, in at least one month in the year, based on national... |
