Abstract

Four dispersal stages of the nematode Bursaphelenchus mucronatus (Nematoda: Aphelenchoididae) were surveyed in Finland during the summers 1989 and 1990 examining field collected conifer beetle (Coleopterea) adults of the following species: Monochamus sutor, M. galloprovincialis, Acanthocinus aedilis, Rhagium inquisitor, Asemum striatum, Spondylis buprestoides and Hylobius abietis. All but the last one (Curculionidae) belong to genus Cerambycidae. The two Monochamus species were the only ones carrying B. mucronatus fourth dispersal stages, total number of nematode larvae per beetle being higher in M. galloprovincialis. The frequency of infestation was 24% in M. galloprovincialis and 14% in M. sutor but the difference eas not statistically significant.
