Natural predatory enemies of the erineum strain of Colomerus vitis (Pagenstecher) (Acari, Eriophyidae) found on wild grapevine populations from southern Spain (Andalusia)

The Eurasian wild grapevine, Vitis vinifera L. subspecies sylvestris (Gmelin,) Hegi constitutes a dioecious relative of cultivated grape varieties. It constitutes an important phytogenetic resource, threatened by human activities. The most frequent phytophagous species on this European wild vine is the erineum strain of Colomerus vitis (Pagenstecher) (Acari, Eryophyidae). The aim of the present paper is to identify the natural enemies of the cited mite in wild grapevine populations situated in southern Spain. Results indicated that such kind of predatory biocenosis is integrated by Phytoseiidae (Euseius stipulatus, Kampimodromus sp., Neoseiulella litoralis, Phytoseiulus persimilis, Typhloseiella isotricha, Typhlodromus phialatus, Typhlodromus rhenanoides), Tydeidae (Orthotydeus caudatus,Tydeus caudatus), and dipteran, Cecidomyiidae (Arthrocnodax vitis).
