Dietary yeast affects preference and performance in .

Yeasts play an important role in nutrition physiology and host attraction of many species, and associations with various yeast species are documented for several drosophilid flies. The pest (Matsumura) has a predominant association with the yeast However, research has not been conducted on the nutritional physiology of the yeasts associated with (spotted wing drosophila). Therefore, in this study, we determined whether dietary yeast was nutritionally relevant and whether yeast species closely associated with positively affected life-history traits.
