title: Attraction of pinewood nematode to endoparasitic nematophagous fungus Esteya vermicola.
abstract: The investigations on attraction of nematodes to nematophagous fungi have mostly dealt with the nematode-trapping species. Esteya vermicola is the endoparasitic fungus of pinewood nematode (PWN) with high infection activity. In the present study, the attraction of PWNs to E. vermicola was investigated. It was confirmed that the living mycelia and exudative substances of E. vermicola were attractive to PWN. Compared with the nematode-trapping fungus A. brochopaga as well as nematode-feeding fungus B. cinerea, E. vermicola showed the significantly strongest attraction ability to nematode. It therefore appeared that the attraction ability reflects the dependence of the fungi on nematodes for nutrients. Furthermore, a new method was developed and used in the study to confirm the effect of volatile substances for the attraction of nematode to fungi. The results suggested that the attractive substances were consisted of avolatile exudative and volatile diffusing compounds.
