Abstract

Fungal discolouration of wood was found associated with galleries of Coryphodema tristis in grapevines. The mean percentage damage caused by larvae and fungal discolouration was 14,8 % and 13,5 % respectively. Twelve fungal species were isolated from the discoloured region. None of these fungi were transmitted from one generation of the insect to the next.
