As a result of the detection of the pinewood nematode Bursaphelenchus xylophilus in Portugal, and its subsequent spread to Spain, intense surveys were conducted to screen for the presence of Bursaphelenchus species in Romania. Herein, we report recent surveys of insects potentially vectoring Bursaphelenchus species collected using trap trees or pheromone‐baited traps placed in the forest. Trap felled spruce trees ( Picea abies ) and pheromone‐baited traps were installed in six different counties in Romania (Brașov, Sibiu, Suceava, Hunedoara, Timiș and Dâmbovița). Ten different species of insects distributed among Curculionidae and Cerambycidae were obtained. Nematodes were extracted from insects and observed to validate the presence of Bursaphelenchus specimens. One female identified as Monochamus sutor was the only specimen carrying nematodes in the genus Bursaphelenchus . Nematodes were identified as B. mucronatus based on morphological and molecular features. This is the first detection and report of natural spread of B. mucronatus in Romania. The absence of B. xylophilus was confirmed in the areas of Romania surveyed in this work.
