Impact of Nectar Composition and Nectar Yeasts on Volatile Emissions and Parasitoid Behavior

Nectar yeasts can significantly influence the scent of floral nectar and therefore foraging behavior flower-visiting insects. While these effects likely depend on chemistry yeast species, their joint impact volatile profiles associated insect responses remain poorly understood. Here, we used four synthetic types varying in sugar amino acid concentration two specialist (Metschnikowia gruessii Metschnikowia reukaufii) to investigate how composition species affect olfactory generalist aphid parasitoid Aphidius ervi. Olfactometer assays showed that A. ervi females preferred fermented nectars with high acid-low content (HL) low acid-high (LH) content, regardless being by M. or reukaufii, over non-inoculated nectars. This effect was not observed for (LL) (HH) content. Moreover, LL became even repellent parasitoids. GC-MS analysis organic compounds (VOCs) revealed VOC depended type (i.e., chemical composition), interaction. Whereas propyl acetate, isobutyl styrene, α-guaiene pentyl-octanoate were LH nectars, ethyl acetate E-methyl isoeugenol mainly HL suggesting possible involvement attraction In contrast, isopropyl-hexadecanoate non-attractive Altogether, our results indicate has a strong when subsequently behavior.
