One hundred eighty-two newly emerged M. sutor beetles, originating from central and northern Sweden, were allowed to feed on branch sections of Scots pine, Pinus sylvestris L., and Norway spruce, Picea abies (L.) Karst., for two to six weeks. Twenty-two of these beetles transmitted the nematode Bursaphelenchus mucronatus Mamiya and Enda 1979, to the branches they were feeding on. After two weeks of feeding, 63 M. sutor male-female pairs were allowed access to bolts of Scots pine and Norway spruce, suitable for oviposition, for three weeks. Seven of these pairs transmitted Bursaphelenchus mucronatus to the bolts of both tree species.
