“…This was primarily due to the absence of monitoring of the S. noctilio population, a neglected biological control programme, and overstocked stands ( Haugen, 1990 ). This outbreak resulted in the death of approximately 4.8 million trees before 1990 ( Haugen and Underdown, 1990b;Bedding and Iede, 2005 ). Subsequently, there have been no serious outbreaks reported from Australia.…”

1 Sirex noctilio has resulted in one of the most damaging biological invasions of pine forestry in the southern hemisphere. 2 An intensive, integrated control programme has been developed for this pest and is generally considered very successful. However, a critical comparison of S. noctilio infestations and control efforts throughout the southern hemisphere reveals that control has not been uniformly effective. Of particular concern is the apparently unexplained variability in establishment and success of biological control agents, including various parasitic wasps and the parasitic nematode Deladenus siricidicola . 3 An overlooked aspect in the establishment of the biological control interventions for S. noctilio is the potential influence of genetic bottlenecks on the ability of the agents to adapt to different environments and different populations of S. noctilio . 4 Despite established biological control agents, stress in forests caused by silvicultural practices or the environment will predispose trees to heavy infestation. Unfortunately, improved silvicultural practices are not always economically feasible and environmental changes are often unavoidable. 5 Sirex noctilio continues to pose a serious threat to pine forestry in many areas.Despite extensive earlier research into a single integrated control for S. noctilio , it is important to recognize that such a strategy will probably require significant local adaptation in new areas of infestation and over time.

“…Besides these causes, pathogens were implicated as main cause of several dieback events [3,6]. Other suggested causes for dieback are interspecific competition [7], insect outbreak [8], and air pollutants [9]. Thus far, the factors being considered for contributing to dieback are mainly environmental with little attention paid to the self-regeneration of the target populations through sexual reproduction during plant dieback.…”

“…D. siricidicola sterilizes its siricid woodwasp host, Sirex noctilio F. (Bedding, 1972). D. siricidicola has been used for the practical biological control of S. noctilio in Australia (Bedding, 1993;Bedding and Akhurst, 1974;Haugen, 1990;Haugen and Underdown, 1990). Hundreds of isolates of Deladenus species were screened for potential to control the woodwasps (Bedding, 1993).…”

Density independent propagation of the entomophagous and mycetophagous nematode, Contortylenchus genitalicola (Tylenchida: Allantonematidae), within the Japanese pine sawyer, Monochamus alternatus (Coleoptera: Cerambycidae)Hajime KosakalThe entomophagous and mycetophagous nematode, Contortylenchus genitalicola, is a candidate biological control agent of the Japanese pine sawyer, Monochamus alternatus , a serious forest pest. In the present study, the propagational traits of C. genitalicola within M. alternatus adults were investigated by counting the numbers of nematode females and progenies (juveniles and eggs) in the adult hosts and weighing host pupae as the host body size. Propagation of C. genitalicola within M. alternatus adults was not affected by the host sex and body size. The total number of nematode progenies within hosts increased with the number of female nematodes, whereas the mean number of nematode progenies per female nematode did not decreased with the increased number of female nematodes within hosts. This indicates that the propagation of C. genitalicola in M. alternatus is density independent. The density independent propagation is considered advantageous for the biological control of M. alternatus using C. genitalicola because this may cause larger production of the infective stages of nematodes for subsequent infection than the density dependent, and is one of the factors to limit host density under the carrying capacity in a theoretical model.
