Colomerus Newkirk & Keifer, 1971 is an eriophyid genus described by Newkirk and Keifer about 43 years ago, that contains species from all continents, except Antarctica. They live mostly on dicotyledonous plants. Colomerus novahebridensis Keifer, 1977 was described from coconut (Cocos nucifera L., Arecaceae) fruits from Vanuatu. A description of a Thai population of this species is given in this...

Bud mite, blister mite ( Colomerus vitis Pagenstecher), and rust mite ( Calepitrimerus vitis Nalepa) (Acari: Eriophyoidae) are recognized grapevine pests. Much of the biology and ecology of these pests is poorly understood. We used two types of molecular markers to gain further insight into the breeding biology and population structure of these mites, using individuals collected from sites arou...

In recent years, Colomerus vitis has caused serious economic losses due to reduced grape production in Xinjiang (northwest China). Several rootstock varieties have been reported improve the resistance of Cabernet Sauvignon vitis. This study explored influence with different rootstocks on particular, Sauvignon/Cabernet (CS/CS) was selected as control, and grafted five resistant (3309C, 1103P, 14...

the grape erineum mite (gem), colomerus vitis (pagenstecher) (acari: eriophyidae) is considered to be one of the most important pests, that sometimes causes irreversible damages to grapevine cultivars in western parts of iran. studies were carried out in order to find natural enemies associated with gem, during 2011-2013. results indicated that natural enemies included two species of predatory ...

A Vitis hybrid-Vitis coignetiae red wine was vinified by fermentation of a mixture of a Vitis hybrid-Vitis coignetiae must with Saccharomyces cerevisiae KCTC 7904 at 25℃ for 10 days. The Vitis hybrid-Vitis coignetiae red wine showed high antihypertensive angiotensin I-converting enzyme (ACE) inhibitory activity (67.8%) and antioxidant activity (76.7%). The antihypertensive ACE inhibitor in the ...

Grape must harbors a complex community of yeast species responsible for spontaneous alcoholic fermentation. Although there are detailed studies on the microbiota of Vitis vinifera L. grapes, less is known about the diversity and behavior of yeast communities present on fermenting grape must from other species of Vitis. In this work, we used a culture-dependent method to study the identity and d...
