F.  aChemical vs entomopathogenic control of Thaumastocoris peregrinus (HemipterabThaumastocoridae) via aerial application in eucalyptus plantations.h[electronic resource]  c2019  aThe 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 certifcations. Bio-insecticides may have similar efciency 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 diferent 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 21days 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 efciency 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.  aEucalyptus  aPest control  aEucalipto  aControle  aPercevejo bronzeado  aPraga florestal  aThaumastocoris peregrinus1 aDAL POGETTO, M.
