Interactions of moulds and insects

Filamentous fungi and saprophage insects are suspected to be competitors on decaying organic matter. Both organisms have equal requirements considering habitat and nutrition. Insect larvae negatively influence mould development, but filamentous fungi can be an important cause of mortality of insect larvae. These competitions in insect-mould interactions have largely been ignored.

Using a combination of experimental ecology and functional genomic techniques the function of moulds secondary metabolites (e.g. mycotoxins) as a chemical defence in insects-moulds-interactions as well as the influence of these competitors at trophic interaction between insects ought to be investigated. For our research the vinegar fly Drosophila melanogaster and its natural mould antagonist Aspergillus were used as a form of ecology model system. By the use of gene expression experiments from secondary metabolism of moulds which interact on festered matter with the antagonistic Drosophila larvae we want to identify fungal target genes. Furthermore the expressions of target genes have to be manipulated to obtain fungal mutants to analyse their use as competitors with insect larvae. The aim of these experiments is to show the importance of fungal secondary metabolism and if these products offer a defence against the concurrent insect larvae respectively. Therefore the consequence on evolutionary fitness of the fungi and insect will be analysed.
