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.

In organic apple orcharding there is a continuous need for natural fungicides effective against Venturia inaequalis (Cooke) Winter, the causal agent of apple scab. In this study an in vitro assay is presented for determining the germination inhibitory potential of extracts and pure compounds. From a screening of plant extracts, the methanol extract of Morus root bark revealed distinct V.
