The parasitic nematode Deladenus siricidicola is considered to be the key biological control agent of Sirex noctilio in Australia. Nematode levels were assessed for wood chips (approximately 6 x 6 x 1.5 cm each) taken from 21 sirex-infected trees in Pinus radiata plantations in South Australia during July 1988. The wood chips were cut out of the sapwood with an axe.
