The insect pest invasions in forest plantations were significantly increased in the latest decades. The forestry genera most planted for commercial purposes in the world are Eucalyptus, Pinus, Populus, Acacia, Toona, among others. In South America species of Populus and Salix are secondary in importance to industry but are commonly used as urban trees. The leaf beetles of the Chrysomelidae family are the main insect pest affecting poplar plantations in North America, especially of the genus Chrysomela, where Chrysomela scripta is consider the most harmful species. C. scripta is endemic of North America, being more abundant in poplars plantations in the United States. The aim of this work was report for the first time the presence of C. scripta in Brazil. In July, 2016 some beetles unidentified were observed feeding in trees of Salix nigra and Populus deltoides in an urban area of Botucatu municipality in Su00e3o Paulo State, Brazil, causing complete defoliation. In June 2017 were observed in Piracicaba. Adults, larvae, pupae and eggs were collected and reared in laboratory. These specimens were identified as the exotic species Chrysomela scripta (Coleoptera: Chrysomelidae). This is the first detection of this exotic pest outside their natural range is important for the development of the sanitary surveillance strategies to prevent the expansion of this species and evaluate their impact in Salix humboldtiana, a native species. Studies to determine the bioecology and distribution of C. scripta in Brazil are ongoing.
