The effect of the presence of beetle adults (Monochamus galloprovincialis, Acanthocinus aedilis, Rhagium inquisitor and Hylobius abietis) in Scots pine wood chips on the occurrence of the third (Lᵢᵢᵢ) and the fourth (Lᵢᵥ) dispersal stage of the nematode Bursaphelenchus mucronatus was studied. Possible infestation of the beetles with Lᵢᵥ of the nematode while being in close contact with the pine chips was also explored. Adults of M. galloprovincialis and A. aedilis contributed to B. mucronatus Lᵢ formation in the chips. Callow adults of M. galloprovincialis were more efficient elicitors of moulting of Lᵢᵢᵢ into Lᵢᵥ than emerged beetles of the same species. Only M. galloprovincialis adults became infested with Lᵢᵥ callow beetles containing more nematodes than emerged beetles.
