The influence of Amylostereum areolatum diversity and competitive interations on the fitness of the Sirex parasitic nematode Deladenus siricidicola

Informally Refereed

Abstract

The Sirex noctilio (woodwasp - Amylostereum areolatum (fungus) complex has caused substantial losses to pine industries in its introduced range. The nematode Deladenus siricidicola that parasitizes S. noctilio and feeds on A. areolatum is widely used as a biological control agent for S. noctilio, but not with consistent success. This variable success could be due to factors that influence the feeding and reproductive ability of the nematode on A. Areolatum. We test two main hypotehese that emerge from this prediction. First, we compared the survival of D. siticidicola on the South African field strain and the Australian laboratory strain of A. areolatum, to examine a possible incompatibility between nematode and fungal strain.
