Alternative Strategy:
A. areolatum is a basidiomycete that causes a white rot of a broad range of conifers. Its invasiveness arises from a symbiotic association with wood wasps of the genus Sirex. Control strategies therefore need to address both the fungus and they symbiotic wasp.The tylenchid nematode Beddingia (= Deladenus) siricidicola, discovered in New Zealand and later found in Europe lives in and feeds on A. areolatum colonies in trees and also infects Sirex larvae and female wasps. Because it has a separate cycle of growth and reproduction based on fungus feeding, it can cause a greater reduction in wasp numbers. The nematode can be raised in cultures of the fungus and injected into trees for effective control of the wasp (Bedding, 1995). B. siricidicola is currently under evaluation for use in the USA (Williams and Mastro, 2009.
