“…Ten trees were evaluated per plot with the collection of ten leaves from the middle third of the crown of each one 43 . The leaves were removed from the plant and packed in sealed paper bags which were transported to the FCA/UNESP Biological Control of Forest Pests Laboratory in Botucatu, São Paulo state, Brazil, where live insects were counted.…”

The Thaumastocoris peregrinus spread to eucalyptus plantations in many countries. Chemical control is a questionable measure, mainly due to the environmental impact, high cost and moreover has the use restricted by the forest certifications. Bio-insecticides may have similar efficiency to chemical products to control T. peregrinus . The chemical thiamethoxam, thiamethoxam + lambda-cyhalothrin, acephate and the microbial Beauveria bassiana and Metarhizium anisopliae insecticides were tested at different doses to manage T. peregrinus . The products were sprayed on eucalyptus plants using aircraft and populations of this insect were counted before application and at 1, 14 and 21 days afterwards (DAA). Ten eucalyptus trees were evaluated per plot, with the collection of ten leaves from the middle third of the crown of each tree, and the number of T. peregrinus nymphs and adults obtained per leaf was determined. All the chemical insecticides had similar control at 1 DAA for T. peregrinus nymphs and adults. At 14 DAA, the number of T. peregrinus nymphs and adults on eucalyptus leaves was similar for the chemical and microbial insecticide treatments. At 21 DAA the control efficiency of T. peregrinus nymphs and adults was higher than 80% with all insecticides. The entomopathogenic insecticides have potential for aerial application to control T. peregrinus nymphs and adults and provide viable and environmentally-friendly alternative to manage this pest.

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 biological control methods favors integrated pest management. the objective of this study was to evaluate the selectivity of commercial products based on B. bassiana, M. anisopliae and the chemical bifenthrin on the parasitoid C. noackae and its parasitism on T. peregrinus eggs. the selectivity test followed the standards recommended by the international organization for Biological control (ioBc). Beauveria bassiana has selectivity to parasitism as well as viability, but was slightly harmful to C. noackae adults; M. anisopliae was innocuous to adults and to the viability of the offspring of this parasitoid, but it reduced the parasitism rate; and bifenthrin did not show selectivity to this parasitoid. The area of commercially planted forests in the world increased from 167.5 to 277.9 million hectares from 1990 to 2015 1. Brazil presently has 5.7 million hectares of Eucalyptus plantations with 24%, 17% and 15% of them in the states of Minas Gerais, São Paulo and Mato Grosso do Sul, respectively. The wood from these plantations is mainly destined for the pulp industry, with a production of 21 million tons in 2018 2,3. Insect pests of Australian origin detected in planted forests during the last three decades on a global scale may reduce Eucalyptus productivity 4. The bronze bug, Thaumastocoris peregrinus Carpintero & Dellapé (Hemiptera: Thaumastocoridae), was first detected in Brazil in 2008 in the states of São Paulo and Rio Grande do Sul, and has since dispersed to other Eucalyptus-producing states 5. This insect develops and produces fertile offspring on most Eucalyptus plantations in Brazil 6. Thaumastocoris peregrinus perforates and causes silvering, tanning, drying and defoliation from Eucalyptus plants 7. Biological control is the most widely-used method for managing T. peregrinus 8. This method includes the egg parasitoid Cleruchoides noackae Lin & Huber (Hymenoptera: Mymaridae), imported from Australia 8,9 , the predators Atopozelus opsimus Elkins (Hemiptera: Reduviidae) 10 and Supputius cincticeps Stäl (Heteroptera: Pentatomidae) 11,12 and entomopathogenic fungi 13,14.
