Measurements were performed with antennae of the old house borer Hylotrupes bajulus, a widespread insect pest of coniferous timbers. Headspace volatiles from timber of Pinus sylvestris were collected and analysed by GC-MS. About 30 compounds were identified in the Kovacs range from 500 to 1200, especially terpenoids and aliphatic alcohols and aldehydes. The antennae of H. bajulus responded to nearly half of the detected volatiles with a peculiar sensitivity for alpha-pinene among the terpenes and for hexanal among the aldehydes.

Although this beetle has been used as a model organism for many decades, there is no systematic knowledge about antennal detection of host and non-host volatiles. Electroantennogram responses to 94 selected volatile organic compounds including alkanes, alkenes, alcohols, aldehydes, ketones, carboxylic acids, esters, terpenoids and aromatic compounds were recorded from both sexes of T.castaneum. Overall, female and male T.castaneum exhibited similar electroantennography (EAG) responses. Compounds eliciting the strongest EAG responses within compound groups of chemical similarity were undecane, 1-hexen-3-ol, octanal, 2-heptanone, hexanoic acid and ethyl hexanoate. Comparison of vapour pressure and EAG amplitudes within homologous series of compounds revealed responses to undecane, octadecane, octanal, nonanal, 2-heptanone, hexanoic acid and octanoic acid as outstanding. Given that systematic EAG screenings have not been conducted before, these are the best candidates for evaluation in future behavioural studies to unravel their potential for application in integrated pest management strategies of T.castaneum."],["dc.identifier.doi","10.1111/jen.12366"],["dc.identifier.isi","000402677200007"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/42265"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","PUB_WoS_Import"],["dc.publisher","Wiley"],["dc.relation.issn","1439-0418"],["dc.relation.issn","0931-2048"],["dc.title","Electroantennographic responses of red flour beetle Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) to volatile organic compounds"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Certain compounds dominate in most of the fungal species. Fungal oxylipins as the eight-carbon volatiles are the most prominent. This raises the question whether such are specific enough to qualify as appropriate host cues for a fungivore. We could demonstrate differentiated responses of the fungivorous beetle Bolitophagus reticulatus to eight-carbon volatiles: Nine eight-carbon volatiles were identified with GC-MS from its host fungus Fomes fomentarius. 1-Octen-3-ol, 3-octanone and 3-octanol induced contrasting behaviour of beetles in olfactometer bioassays. Electroantennographic experiments investigating the beetle olfactory sense revealed distinguishable antennal responses. Moreover, their individual release from F. fomentarius fruiting bodies changes not only considerably, but also independently over successive stages of beetle colonisation. Concentrations of attractive and repellent eight-carbon volatiles correlate to frequency of beetles in the field and further substantiate their relevance as host cues. Our results show that a specialist fungivore is able to differentiate the most common eight-carbon volatiles of fungi to assess host quality. Key roles and marked similarities of fungal to plant oxylipins suggest a comparable importance of eight-carbon volatiles to fungivores as green leaf volatiles have to herbivores."],["dc.identifier.doi","10.1007/s00049-014-0151-8"],["dc.identifier.isi","000332758600003"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/33907"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.publisher.place","Basel"],["dc.relation.issn","1423-0445"],["dc.relation.issn","0937-7409"],["dc.title","Ubiquitous eight-carbon volatiles of fungi are infochemicals for a specialist fungivore"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
