Infestation of four coleopteran species by the pine wood nematode Bursaphelenchus xylophilus (Nematoda, Aphelenchoididae) living in wood chips.

Six coleopteran species were tested for their susceptibility to infestation by dauerlarval or propagative stages of Bursaphelenchus xylophilus (Steiner & Buhrer 1934), living in wood chips: Monochamus scutellatus (Say), Rhagium inquisitor (L.), Asemum striatum (L.) (Cerambycidae), Hylobius pales (Herbst) (Curculionidae), Dendroctonus valens (LeConte) (Scolytidae) and Pytho sp. (Salpingidae). M. scutellatus and R. inquisitor very frequently became infested by dauerlarvae, though the numbers of larvae per beetle were low. A. striatum and H. pales also became infested by dauerlarvae, but the frequency of infestation and the numbers per beetle were considerably lower. In addition, one male of H. pales became infested by 20 individuals of propagative stages.
