Summary: | The woodwasp Sirex noctilio (Fabricius) (Hymenoptera: Siricidae) is one of the main pests of Pinus plantations in South America. The aim of this study is to report the occurrence of S. noctilio in Pinus taeda in Botucatu, Sao Paulo, Brazil. The surveys were carried out in the arboretum of Faculdade de Ciencias Agronomicas (FCA) da Universidade Estadual Paulista "Julio de Mesquita Filho" (UNESP), campus Botucatu, SP where six species of Pinus are distributed in blocks of 100 trees. Resin beads were observed on the trunks and stems of Pinus species. In post-flight evaluation it was reported that 8.77% of P. taeda trees showed symptoms of oviposition by S. noctilio. A female S. noctilio was found performing oviposition. Sirex noctilio is present in Botucatu, increasing the geographical distribution of the pest in Sao Paulo State. Key words: Sirex noctilio, exotic pest, forest pest, occurrence, pine.
