Numerous studies suggest that fungal chemicals can affect insects in many different ways. Here, we apply the terminology established by insect-plant ecologists for categorizing the effect of fungal allelochemicals on insects and for evaluating the application potential of these chemicals in insect pest management. Our literature survey shows that fungal volatile and non-volatile chemicals have an enormous potential to influence insect behavior and fitness. Many of them still remain to be discovered, but some recent examples of repellents and toxins could open up new ways for developing safe insect control strategies. However, we also identified shortcomings in our understanding of the chemical ecology of insect-fungus interactions and the way they have been investigated. In particular, the mode-of-action of fungal allelochemicals has often not been appropriately designated or examined, and the way in which induction by insects affects fungal chemical diversity is poorly understood. This review should raise awareness that in-depth ecological studies of insect-fungus interactions can reveal novel allelochemicals of particular benefit for the development of innovative insect pest management strategies."],["dc.description.sponsorship","German Research Foundation, DFG [RO3523/3-2]"],["dc.identifier.doi","10.1007/s00253-016-7573-x"],["dc.identifier.isi","000378725700002"],["dc.identifier.pmid","27147531"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/40182"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","1432-0614"],["dc.relation.issn","0175-7598"],["dc.title","Fungal allelochemicals in insect pest management"],["dc.type","review"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

This study tests the influence of volatiles emitted by micro-fungi, yeast and mould, on the foraging behaviour of facultative fungivorous Drosophila melanogaster larvae. We hypothesised that establishing or avoiding contact with edible yeast (host fungus) and inedible, toxic mould (non-host fungus) is regulated by fungus-specific variation in volatile production. In particular, we expected the non-host fungus to produce specific volatiles that repel fly larvae and thus contribute to signal inedibility. By quantifying innate variation in arrival of individual D. melanogaster larvae at colonies of the mutualist yeast Candida californica or of the antagonistic mould Penicillium expansum, we found the yeast to attract more rapidly a larger number of larvae than the mould did. The developmental stage (young, vegetative vs. old, sporulating) of P. expansum did not affect arrival of larvae at fungal colonies. We used gas chromatography coupled with mass spectrometry (GC-MS) to identify the composition of fungal volatiles. Four compounds appeared to be yeast-specific, twenty to be mould-specific volatiles. Eight volatiles were consistently produced by both young and old P. expansum. Two compounds, 3-methyl-1-butanol and 2-methyl-1-propanol, were released by P. expansum (young and old) as well as C. californica. Time-dependent behavioural response profiles of similar to 750 D. melanogaster larvae revealed innate attraction to three alcohols produced by yeast and/or moulds and to two yeast-specific organic acids. We found no indication of a repellent effect of mould-specific compounds, including terpenoids like geosmin known to elicit strong avoidance behaviour of adult D. melanogaster in response to harmful microbes. Also, synthetic mould and yeast-specific blends of attractive compounds were equally attractive to the larvae. With respect to the species combinations investigated in this study, we hypothesize that qualitative differences in fungal volatile profiles are of minor relevance in how Drosophila larvae locate and probably discriminate between fungi of varying suitability."],["dc.description.sponsorship","DFG (German Research Foundation) [RO3523/3-1, RO3523/3-2]"],["dc.identifier.doi","10.1007/s00049-015-0197-2"],["dc.identifier.isi","000360846200005"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/35897"],["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","Volatile-mediated location of mutualist host and toxic non-host microfungi by Drosophila larvae"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
