Eriophyidae Trombidiformes Colomerus vitis


The worldwide grapevine pest, Colomerus vitis (Trombidiformes: Eriophyidae), comprises three strains recognised by different plant symptoms: bud, erineum, and leaf curl strains. It has been hypothesised that these may represent different cryptic species, each causing a specific symptom.
