This is the first report of the weevil Naupactus curtus Boheman favouring Ascochyta disease on coffee plants in Brazil. From August to October 2008 (the period of N. curtus occurrence), six coffee crops were monitored with the evaluation of 565 coffee plants. Leaves showing injuries caused by N. curtus and Ascochyta coffeae strains were found in Ponte Nova and Jaboticatubas, Minas Gerais, Brazil. A positive and significant correlation between the number of lesions caused by the weevil and those resulting from an infection by the Ascochyta disease was observed. These results suggest that insect control may be an alternative in order to reduce disease proliferation.
