Detection and identification of Amylostereum areolatum (Russulales: Amylostereaceae) in the mycangia of Sirex nigricornis (Hymenoptera: Siricidae) in central Louisiana.
The woodwasp Sirex noctilio F. (Hymenoptera: Siricidae) has become established in North America. A primary tactic for the management of S. noctilio in the southern hemisphere has been the development of a biological control agent, Deladenus siricidicola Bedding. This nematode has a bicyclic life cycle including a mycetophagous free-living and parasitic cycle. During oviposition, female Sirex wo...
متن کاملDeladenus siricidicola, bedding (Neotylenchidae) parasitism evaluation in adult Sirex noctilio, Fabricius, 1793 (Hymenoptera: Siricidae).
This work aimed to evaluate the Deladenus siricidicola, Bedding (Neotylenchidae) parasitism in adults Sirex noctilio, Fabricius, 1793 (Hymenoptera: Siricidae). Timber was sampled by cutting out pieces of 0.80 m in length in Sirex noctilio attacked and Deladenus siricidicola inoculated Pinus taeda. Longs were 15-20 cm in diameter, according to the tree age. Samples were packed in gauze-cages, fo...
متن کاملBiochemistry of Anhydrobiosis in Beddingia siricidicola, a Biological Control Agent of Sirex noctilio.
Proto-anhydrobiosis of the nematode, Beddingia siricidicola, was achieved by incubation in polyethylene glycol or various concentrations up to 4 M of glycerol. The associated changes in the levels of glycerol, unbound proline, trehalose, lipids, and glycogen were determined by alkylation strategies, followed by gas chromatography or gas chromatography/mass spectrometry. The level of glycerol re...
متن کاملMolecular phylogeny of species in the genera Amylostereum and
Analyses of DNA sequences from the internal transcribed spacer (ITS) region of the nuclear rDNA and from a portion of a manganese-dependent peroxidase gene were used to assess the species in Amylostereum, including isolates from the mycangia of horntails, decay, and basidiomes. Four species are recognized: A. areolatum, A. chailletii, A. laevigatum, and A. ferreum. An unidentified Amylostereum ...
متن کاملThe effect of Sirex noctilio infestation and fire damage on the chemical composition of South African-grown Pinus patula pulpwood
The South African pulp industry is reliant on Pinus patula as a main constituent of the softwood raw material. However, trees in plantations can periodically be physiologically stressed due to a variety of biotic and abiotic factors. Damaged or dead trees can constitute a loss of pulpwood production to the mill, with the economic consequence of having to source the timber elsewhere on the open ...
