New Insights into the Ecological Interaction Between Grape Berry Microorganisms and Drosophila Flies During the Development of Sour Rot

摘要: In this work, we studied the ecological interactions between grape berry microorganisms and Drosophila sp. flies involved in sour rot disease during ripening. After veraison total microbial counts of berries affected by increased from about 2 log CFU/g to more than 7 CFU/g. Berry damage provoked a clear shift yeast diversity basidiomycetes ascomycetous fermentative species. The latter were mostly Pichia terricola, Hanseniaspora uvarum, Candida zemplinina, Zygoascus hellenicus. However, these species not able produce metabolites characteristic (gluconic acetic acids) inoculated berries. On contrary, acid bacteria Gluconacetobacter saccharivorans produced high levels acids, mainly when incubated presence insect Sour was observed bunches physically separated insects, even artificially injured. wounds made skin healed absence thus preventing development rot. Therefore, vineyard, induction depends on contamination wounded consortium—yeasts bacteria—transported drosophilid insects which disseminate among damaged plant defense mechanisms are effective lead healing, spread. Thus, showed that act as vector for associated with disease.
