Multiple origins of cultivated grapevine (Vitis vinifera L. ssp. sativa) based on chloroplast DNA polymorphisms
The results suggest the existence of at least two important origins for the cultivated germplasm, one in the Near East and another in the western Mediterranean region, the latter of which gave rise to many of the current Western European cultivars.
Genetic diversity of wild grapevine populations in Spain and their genetic relationships with cultivated grapevines
The genetic relationships between wild and cultivated grapevines could suggest a genetic contribution of wild accessions from Spain to current Western cultivars, and the model‐based approach implemented in the software structure identified four genetic groups, with two of them fundamentally represented among cultivated genotypes and two among wild accession.
Assessment of pollen dimorphism in populations of Vitis vinifera L. subsp. sylvestris (Gmelin) Hegi in Spain
A comparative scanning electron microscopy study and biometric analysis of pollen of 14 Spanish Vitis vinifera L. subsp. sylvestris (Gmelin) Hegi populations was performed. In all the investigated…
Growth inhibitory activity of Daphne gnidium L. (Thymelaeaceae) extracts on the elm leaf beetle (Col., Chrysomelidae)
A significant reduction of larval survival and adult emergence, together with an increased length of the larval period, heavy reduction of weight gain and appearance of malformations in emerged imagines were observed in presence of spurge flax extracts.
Xylotrechus arvicola (Olivier) (Coleoptera, Cerambycidae), a new impacting pest on Spanish vineyards
Symptoms caused by the pest, the identification of 7 associated wood fungal species living in galleries excavated by larvae, some data about the evolution of the infestation during 8 years in the same plot and the different levels of susceptibility exhibited by three grape varieties are presented.
Comparative analysis of wild and cultivated grapevine (Vitis vinifera) in the Basque Region of Spain and France
Forecasting the flight activity of Lobesia botrana (Denis & Schiffermüller) (Lepidoptera, Tortricidae) in Southwestern Spain
Analysis of data on male catches in sex pheromone traps recorded over a 12‐year period confirmed the minor importance of the first generation which appears during flowering time, both in terms of male trap catches and damage of L. botrana to the inflorescences.
Natural predatory enemies of the erineum strain of Colomerus vitis (Pagenstecher) (Acari, Eriophyidae) found on wild grapevine populations from southern Spain (Andalusia)
Results indicated that such kind of predatory biocenosis is integrated by Phytoseiidae, which are the natural enemies of the cited mite in wild grapevine populations situated in southern Spain.
Seasonal Trends in the Social Composition and Inside-Trunk Distribution of Kalotermes flavicollis (Isoptera: Kalotermitidae) Colonizing Grapevines
A pattern of seasonal migrations of the termites inside the trunk was inferred, with upward movements from spring to autumn and downward movements from autumn to winter, and Pseudergates and reproductives maintained their proportions and locations almost unchanged during the year.
Characterization of Vitis vinifera L. subspecies sylvestris (Gmelin) Hegi in the Ebro river Basin (Spain)
The characterization of this phytogenetic resource was based on an ampelographic description of the male and female individuals and an evaluation of their sanitary state, which shows that the imported North American downy and powdery mildews are the main pathogens, but no symptoms caused by phylloxera on roots were found.
