A three years study (2008-2010) was carried out in two organic managed vineyards in western Sicily in order to verifyboth the influence of different cultivars and microclimatic conditions on grape moth infestation and on mould infectionsof grapes. Observations were done on two autochtonous (Inzolia and Catarratto) and four international (Chardonnay,Cabernet Sauvignon, Syrah and Merlot) cultivars. Results showed a different degree of infested grapes among the differentcultivars in both farms but also a different level of infestation between the two farms for a same cultivar. Chardonnaywas the most infested cultivar by the grape moth larvae, while Merlot was the less infested. Botrytis cinerea was almostabsent on the majority of the cultivars, while the sour bunch rot was always present. This disease sometimes was presenton all infested grapes. On the other hand Aspergillus was present in very low levels on the majority of the cultivars.
