D3241: Phytophagous mites of vineyards in Arequipa, Perú

Phytophagous mites are considered key pests in vineyards of worldwide however, there is a lack of information about the species and distribution in Peru. A survey of phytophagous mite in six vineyards to investigate diversity of the plant feeding mites of Arequipa grapevine. Sampling were done in June-July of 2019 and February-March 2020 period and included conventional farms and backyard orchards found in the Winelands of the Arequipa. At each site vine branches and leaves were collected, inspected with a microscope, mites mounted in Hoyer’s Medium and identified. Four species were found, of which Brevipalpus sp (Tenuipalpidae) was the dominant species in all vineyards, Colomerus vitis (Eriophyiidae), Olygonychus punicae and Olygonychus beeri (Tetranychidae) are less frequent. The implications of these results for vineyard mite distribution and research prospects are discussed.
