Description:	Brazil has about five million hectares of forest plantations of which two million hectares consist of Pinus spp. Most of these stands were planted; they contain a small number of species at high density and receive inadequate forest management. In 1988 an outbreak of Sirex noctilio F. was recorded in Rio Grande do Sul state. Itis present in 250,000 hectares of forest, and is also advancing on Santa Catarina and Paraná states. The use of biological control is the best measure to control S. noctilio. The most effective agent is Beddingia (=Deladenus) siricidicola (Bedding), a nematode that sterilizes the Sirex females. Another parasite, Ibalia leucospoides, bred by the Programa Nacional de Controle À Vespa-da-Madeira (PNCVM) was introduced in 1989. This programme for control of Sirex noctilio is broad in scope; it also includes both the early detection and monitoring of the spread through the use of trap trees and ground inspections and the adoption of preventative measures through adequate forest management. Plans for the future include the introduction of the parasitoid Rinssa persuasoria (L.) and Megarhyssa nortoni (Cresson) to complement the nematode.
