A double-edged sword: Amylostereum areolatum odors attract both Sirex noctilio (Hymenoptera: Siricidae) and its parasitoid, Ibalia leucospoides
The Eurasian woodwasp, Sirex noctilio, is an invasive pest of pines in temperate regions of the Southern Hemisphere, and has been introduced to North America. A parasitoid, Ibalia leucospoides, has been broadly employed for biological control of this pest. Volatiles emitted from the fungal symbiont...

A parasitoid, Ibalia leucospoides, has been broadly employed for biological control of this pest. Volatiles emitted from the fungal symbiont of S. noctilio, Amylostereum areolatum, are reliable cues for S. noctilio and I. leucospoides females to optimize their foraging behavior (host location and host habitat finding) in a chemically complex environment. The headspace volatiles of A. areolatum, were analyzed using coupled gas chromatography-mass spectrometry (GC-MS) and GC-electroantennographic detection (GC-EAD) for both S. noctilio and I. leucospoides females. Analyses revealed that both species could detect several fungal volatiles. In olfactometer bioassays, S. noctilio females were attracted to a 4-component blend of 6-methyl-5-hepten-2-one, trans-3-hexenyl acetate, linalool, and geraniol, while the addition of ρ-anisaldehyde to the blend was necessary for attraction of I. leucospoides females. The results of trap catches in field experiments confirmed that these fungal volatiles in combination with host tree volatiles are attractive to both species, although the release rate of the fungal volatiles is important. These volatiles can serve as a basis for the development of improved lures for both species. | ||

A double-edged sword: Amylostereum areolatum odors attract both Sirex noctilio (Hymenoptera: Siricidae) and its parasitoid, Ibalia leucospoides |
| abstract |
The Eurasian woodwasp, Sirex noctilio, is an invasive pest of pines in temperate regions of the Southern Hemisphere, and has been introduced to North America. A parasitoid, Ibalia leucospoides, has been broadly employed for biological control of this pest. Volatiles emitted from the fungal symbiont of S. noctilio, Amylostereum areolatum, are reliable cues for S. noctilio and I. leucospoides females to optimize their foraging behavior (host location and host habitat finding) in a chemically complex environment. The headspace volatiles of A. areolatum, were analyzed using coupled gas chromatography-mass spectrometry (GC-MS) and GC-electroantennographic detection (GC-EAD) for both S. noctilio and I. leucospoides females. Analyses revealed that both species could detect several fungal volatiles. In olfactometer bioassays, S. noctilio females were attracted to a 4-component blend of 6-methyl-5-hepten-2-one, trans-3-hexenyl acetate, linalool, and geraniol, while the addition of ρ-anisaldehyde to the blend was necessary for attraction of I. leucospoides females. The results of trap catches in field experiments confirmed that these fungal volatiles in combination with host tree volatiles are attractive to both species, although the release rate of the fungal volatiles is important. These volatiles can serve as a basis for the development of improved lures for both species. |

In olfactometer bioassays, S. noctilio females were attracted to a 4-component blend of 6-methyl-5-hepten-2-one, trans-3-hexenyl acetate, linalool, and geraniol, while the addition of ρ-anisaldehyde to the blend was necessary for attraction of I. leucospoides females. The results of trap catches in field experiments confirmed that these fungal volatiles in combination with host tree volatiles are attractive to both species, although the release rate of the fungal volatiles is important. These volatiles can serve as a basis for the development of improved lures for both species.</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Attractant</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Parasitoid</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Woodwasp</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Fungal volatiles</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">White rot fungus</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Olfactory assays</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Cha, Dong H.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Hajek, Ann E.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Teale, Stephen A.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="n">Elsevier</subfield><subfield code="a">Kleinerman, Eugenie ELSEVIER</subfield><subfield code="t">Maximum benefit of chemotherapy for osteosarcoma achieved—what are the next steps?</subfield><subfield code="d">2016</subfield><subfield code="g">Amsterdam [u.a.]</subfield><subfield code="w">(DE-627)ELV024212911</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:54</subfield><subfield code="g">year:2021</subfield><subfield code="g">pages:0</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doi.org/10.1016/j.funeco.2021.101108</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ELV</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">FID-BIODIV</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-PHA</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">35.70</subfield><subfield code="j">Biochemie: Allgemeines</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">42.12</subfield><subfield code="j">Biophysik</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">54</subfield><subfield code="j">2021</subfield><subfield code="h">0</subfield></datafield></record></collection>
