Conteúdo:	Brazil has about five million hectares of forest plantations, of which two million are planted with Pinus spp. South Brazil and São Paulo state have 1.2 million hectares of pine plantations, mainly planted with loblolly pine (Pinus tneda L.) and slash pine (Pinus elliottii Engelm.). These forests provide the raw material for Brazil's pulp and paper, particleboard, ply and veneer, sawing, and resin industries. Due to lack of proper forest management, large areas of pine forests are in bad phytosanitary condition; these forests are vulnerable to pests and diseases. Sirex noctilio (Hymenoptera: Siricidae) registers the largest amount of damage in these forests. A native of Europe, Asia, and Northern Africa, S. noctilio was detected in Brazil in February 1988. By 1997, S. noctilio could be found in 250,000 hectares in Rio Grande do Sul, Santa Catarina, and Paraná states. The nematode Beddingia (=Deladenus) siricidicola (Bedding) (Nematoda: Neotylenchidae) and the parasitode Ibalia leucospoides (Hymenoptera: Ibaliidae) are used to control Sirex. B. siricidicola acts in the reproductive system of female S. noctilio to make them sterile. [. leucospoides attacks eggs and first and second instar larvae. This paper aims at defining sampling methods for the evaluation of damage caused S. noctilio and for monitoring the efficiency of its natural enemies.
