The longhorn beetle Monochamus galloprovincialis (Oliver, 1795)) is a secondary wood-boring pest of pine trees. It is also an important vector of the pine wood nematode (Bursaphelenchus xylophilus (Steiner & Buhrer, 1934)), a quarantine organism that has caused large damage to pine forests in Asia and Portugal. Therefore, it is desirable to monitore the vector and its associated organisms. The aim of this work was to gain insight into the nematodes transmitted by Monochamus galloprovincialis and to evaluate their biological interactions based on literary sources. The trapping of the longhorn beetle was counducted at ten locations in the Czech Republic by teflon coated pheromone traps in 2015, 2016 and 2017. The extraction of nematodes was done by macerating the captured beetles in distilled water. Determination of nematodes was done on the basic of morphological and molecular features. In total, 1704 individuals of Monochamus galloprovincialis were analyzed, 12,6 % of them carried nematodes. Following taxa of nematodes were found: Aphelenchoides sp., Aphelenchoides stammeri, Bursaphelenchus mucronatus, Contortylenchus sp., Deladenus sp., Diplogasteroides sp., Ektaphelenchoides sp., Parasitaphelenchus sp., Parasitorhabditis sp., and larvae of the order Tylenchida.
