Description:	Prevention and control of Sirex noctilio E (Hymenoptera: Siricidae) in Brazil is being accomplished by means of integrated management that involves monitoring for early detection by using trap trees, employing silvicultural practices, and rearing and releasing natural enemies, such as the nematode Beddingia (=Deladenus) siricidicola (Bedding). A commonly used method in plantations with an attack level greater than 50% is the immediate clearcut. Thinning, with the removal of attacked trees, could leave the stand understocked, making its continuation to more advanced ages uneconomic. In this paper, the effects of different attack percentages of S. noctilio on loblolly pine (Pinus taeda L.) growth and production are evaluated in technical and economical terms. The data used were obtained by the simulation of growth and production of forests aged from 12 to 16 years and with attack rates ranging from O to 70%. The study compared, for cach level of attack, the economic advantages of the immediate clearcut with those of the extension of forest rotation age for up to 20 to 30 years. For the extension of the rotation age, the application of established integrated control was considered. The study indicated that if attacked forests are maintained to an age of more than 20 years and integrated pest management is used, higher economic advantages will be realized than if the forest is clearcut on the occasion of the attack, even if the attack rate is over 50%.
