Experimential infestation and seasonal variations in density of Eriophyes vitis Pgst. (Acarina : Eriophyidae) in Turkey. Consequences on earliest treatment
Acarologia 43 (3), 261-265
Abstract: Eriophyes vitis, common on the Kabarcek variety of grapevines was sampled after experiential infestation with 10, 11-30, 30-50 and 50-100 mites/ plant, before and after blossoming. The highest number of adults and larvae was recorded in the beginning of August on plant infested by 10-30 mites. When infested after blossoming, 2876 and 3050 mites (1999 and 2000 respectively) were estimated. The yield loss is significant (500-700 g.). The necessary control against E. vitis was determined when 11-30 mites are seen by plant before blossoming.
