Technical Abstract: The pinewood nematode, Bursaphelenchus xylophilus, and its insect vector, Monochamus carolinensis, develop in close association within wood of infected trees. Formation of pinewood nematode fourth-stage dispersal juveniles (JIVs), the only nematode life stage carried by the vector, occurred almost exclusively in the presence of M. carolinensis late pupae and callow adults. This pattern was observed with live or pulverized M. carolinensis, suggesting that material from the beetle caused JIV formation. M. carolinensis-derived substances associated with adult eclosion were investigated for their role in pinewood nematode JIV formation.
