Deladenus 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 کاملEmergence Phenology and Nematode Associates of the Woodwasp, Sirex nigricornis F. (Hymenoptera: Siricidae), in Arkansas and Mississippi forests
Sirex nigricornis F. (Hymenoptera: Siricidae) is a native woodwasp in eastern North America that inhabits dead and dying pine trees during its univoltine development. Sirex noctilio is native to Eurasia and North Africa and was discovered in the northeastern United States in 2004 after a century of accidental introductions across the Southern Hemisphere. Since then, it has spread to seven state...
متن کاملDetection 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 کاملTest of nonhost angiosperm volatiles and verbenone to protect trap trees for Sirex noctilio (Hymenoptera: Siricidae) from attacks by bark beetles (Coleoptera: Scolytidae) in the northeastern United States.
Sirex noctilio F. (Hymenoptera: Siricidae) is an invasive woodwasp, currently established in northeastern North America. In other regions of the world, stressed trap trees are used to monitor populations of S. noctilio and to provide inoculation points for the biological control nematode Deladenus siricidicola Bedding. However, the operational use of trap trees for S. noctilio in North America ...
