    Abstract:
    This work aimed to evaluate the Deladenus siricidicola, Bedding (Neotylenchidae) parasitism in adults Sirex noctilio, Fabricius, 1793 (Hymenoptera: Siricidae). Timber was sampled by cutting out pieces of 0.80 m in length in Sirex noctilio attacked and Deladenus siricidicola inoculated Pinus taeda. Longs were 15-20 cm in diameter, according to the tree age. Samples were packed in gauze-cages, for daily observations, till S. noctilio adults emergence. The emerged insects were transported, in plastic containers to the laboratory, where they were sectioned and dissected under stereoscopic microscopy to observ the nematode occurrence. From the initially proposed ten units, nine of them were evaluated in a total of 1,810 emerged adult insects, being 1,441 males and 369 females. Nematode parasitism was shown in 267 males and 74 females, in a total of 341 infected insects (18.84%).
