%X the presence of the bronze bug thaumastocoris peregrinus was first reported in the country in june 2009, as a result of the forest surveillance program of servicio agr¨ªcola y ganadero (sag). sucking insects which cause damage as nymphs and adults feeding of sap on the leaves of their hosts. when populations increase, there is a sharp reduction in leaf photosynthetic rate, which can cause decreased growth and sometimes result in complete defoliation of the tree. the aims of this study were to confirm the detection of t. peregrinus, define its range and set the host range within the genus eucalyptus species present in chile. thus, sticky yellow traps were installed in the metropolitan region, municipality of til-til, and in the region of valpara¨ªso; furthermore, national surveys were conducted covering the regions where species of eucalyptus are grown. nine positives (= presence) were detected in the metropolitan area and one in the region of valpara¨ªso. the detection of immature and adult t. peregrinus on eucalyptus camaldulensis indicates that the insect is established in the region. we present actions to be carried out within the official control tasks performed by sag.
