ASSESSING ROLE OF INSECTS IN SOUR ROT DISEASE ETIOLOGY IN VINEYARDS

We have discussed the role of injuries in sour rot disease etiology and how mechanical damage and damage by yellow jackets increase sour rot compared to the only presence of Drosophila fruit flies and microbes associated with sour rot disease in grapes. We have given a brief background about sour rot disease, discussing the impact, symptoms, and factors that cause sour rot. In this presentation, we described the experimental design provided glimpses of sour rot clusters relating to different treatments (Grape berry moth, yellow jackets, mechanical damage, and control in the presence and absence of flies in selected grape clusters. We have presented graphs to describe how injury from yellow jackets and mechanical damage increase the number of flies that emerged from clusters, resulting in more sour rot percentage than in control and berry moth treatment.
