|Abstract: ||BACKGROUND: The pinewood nematode (PWN) Bursaphelenchus xylophilus is an important conifer disease worldwide. It is the
direct cause of the death of millions of pines in south-east Asia (mainly Japan, China and Korea) and has been established
in Portugal since 1999. The phasing out of methyl bromide has created an urgent need for alternative treatment of wood
packagingmaterials. The effect of sulfuryl fluoride (SF), a broad-spectrum fumigant used to control insects, was tested in Pinus
pinaster boards naturally infested by PWN.
RESULTS: Boards were fumigated for 24 h at three different temperatures (15, 20 and 30 ◦C) with dosage ranges of 3169–4407,
1901–4051 and 1385–2141 ghm−3 respectively. Treated wood was sampled for nematode identification and counting, before
treatment and after 24 h, 72 h and 21 days. No survival was found in the 15 ◦Cand30 ◦C treatments, while at 20 ◦C the mortality
ranged from 94.06 to 100%. Some reasons for the survival at 20 ◦C are presented.
CONCLUSION: Results confirm SF to be an effective quarantine treatment for PWNat 15 and 30 ◦C. Further studies are needed to
obtain the most effective dosage at 20 ◦C, and to determine the toxicity of SF fumigation on B. xylophilus at other temperatures,
especially at 25 ◦C.
