“…Overall I. leucospoides parasitism in this study was comparable to the 21.8% I. leucospoides parasitism reported for all woodwasps collectively in S. noctilio's native European range (Spradbery and Kirk 1978), and similar to values reported for S. noctilio in many parts of its introduced range in the southern hemisphere (e.g., Neumann et al 1987, Murphy 1998). The predominance of I. leucospoides in the parasitoid community is consistent with Þndings from other introduced regions, including adjacent areas of the United States of America (Collett andElms 2009, Long et al 2009). Ibalia leucospoides is believed to be a more efÞcient parasitoid, perhaps in part because it uses S. noctilio egg tunnels to locate its hosts.…”

Sirex noctilio F. is an exotic woodwasp now found in eastern North America where it shares natural enemies with native woodwasps of Pinus spp. To study the extent to which native hymenopteran parasitoids and parasitic nematodes could affect woodwasp populations, 60 Pinus trees with symptoms of S. noctilio attack were felled in 2007 and 2008 in Ontario, Canada. Each tree bole was cut into 1-m sections that were placed in individual rearing tubes; emergence was monitored from May to November of the year of felling. Female S. noctilio were dissected to assess parasitism by the nematode Deladenus siricidicola Bedding. Two species of Siricidae emerged from these trees; S. noctilio, which accounted for most of the specimens collected, and S. nigricornis F. Of the three species of parasitoid that emerged, Ibalia leucospoides (Hochenwarth) was the most abundant, accounting for an overall hypothetical Siricidae parasitism rate of almost 20%. This parasitoid emerged over a similar time period as S. noctilio-between early July and early September. Except in trees >15 m in height, parasitism by I. leucospoides generally appeared uniform throughout the bole. Parasitism rates did not vary between the 2 yr, but did between sites in 1 yr. Parasitic nematodes were found in the haemocoel of about one third of S. noctilio females dissected but were never found sterilizing the eggs; none were found in S. noctilio emerging from P. resinosa. These findings suggest that I. leucospoides is currently the primary invertebrate natural enemy of S. noctilio in Ontario.

“…The wasp, introduced to New Zealand around 1905 (Coutts, 1965), spread to Tasmania, Australia, Brazil, Uruguay, Argentina, South Africa, and Chile (Smith and Schiff, 2002;Ciesla, 2003;Collett and Elms, 2009). Most recently, it was discovered in the northeastern United States and subsequently in Canada (Hoebeke et al, 2005;Collett and Elms, 2009). Its introduction into the United States is of concern because, in pine plantations in other parts of the world, it is a serious pest of pine species native to North America (Carnegie et al, 2006).…”

A male-produced pheromone that attracts both males and females was identified for the European woodwasp, Sirex noctilio, a serious pest of pine trees. Males displayed excitatory behaviors when placed in groups, and were attracted to the odors from males that were 2-5-d-old, but not to odors from males that were 0-1-d-old. An unsaturated short-chain alcohol, (Z)-3-decen-1-ol, was discovered in samples collected on SuperQ filters over groups of males and identified by using micro-derivatization reactions and gas chromatography coupled with mass spectrometry (GC-MS). The compound was not detected in volatile samples from females. Gas chromatography coupled electroantennographic detection (GC-EAD) of antennae from males exposed to male headspace odors produced strong antennal responses to the main peak of (Z)-3-decen-1-ol, as well as to an unknown minor component that had a similar retention time. Antennae from both males and females responded to synthetic (Z)-3-decen-1-ol. Several different synthetic candidates for the GC-EAD active minor components were selected based on GC-MS and GC-EAD responses to male headspace collections. These synthetic compounds were tested for antennal activity using GC-EAD, and those that produced strong responses were blended with the major component and tested for male attraction in the Y-tube olfactometer at different concentrations and ratios. Males tested in the Y-tube olfactometer were attracted to a synthetic blend of (Z)-3-decen-1-ol and (Z)-4-decen-1-ol at a ratio of 100:1. Whereas the addition of some suspected minor compounds reduced attraction, the addition of a third compound found in male emanations that produced strong male antennal responses, (E,E)-2,4-decadienal (at a ratio of 100:1:1), resulted in attraction of both males (Y-tube and wind tunnel) and females (wind tunnel).

ABSTRAKPinus radiata merupakan jenis pohon berkayu lunak yang banyak ditanam di Selandia Baru dan Australia. Jamur endofit telah banyak dipelajari pada daun jarum beberapa jenis konifer melalui teknik isolasi jamur namun belum banyak dilakukan pada jenis Pinus radiata. Penelitian ini dilakukan untuk mengetahui kondisi daun jarum P. radiata yang optimal bagi proses ektraksi DNA jamur endofit serta mengetahui jenis-jenis jamur endofit yang berasosiasi dengan daun jarum P. radiata di hutan tanaman Plenty melalui metode PCR secara langsung. Daun jarum yang telah dikeringkan pada suhu ruangan memberikan hasil amplifikasi DNA yang lebih jelas dan konsisten dibandingkan dengan daun yang masih segar serta daun yang telah dikeringkan pada ruang pengering maupun pada alat pengering. Pada penelitian ini, Cap-nodiales merupakan kelompok jamur yang paling banyak dijumpai serta tidak ditemukan jenis jamur patogen. Data sekuen DNA yang diperoleh melalui ektraksi DNA secara langsung dari daun jarum P. radiata mampu memberikan perbedaan serta identifikasi bagi jenis-jenis jamur.Kata kunci: Pinus radiata, jamur endofit, ekstraksi DNA secara langsung, identifikasi jamur
