RODRIGUEZ, Mayra G et al. SYMPTOMATOLOGY AND SPECIES OF Meloidogyne ASSOCIATED WITH GRAPEVINE (Vitis vinifera L. cv. Aramond) IN GÜIRA DE MELENA, Artemisa. (Preliminary results). Rev. Protección Veg. [online]. 2011, vol.26, n.2, pp. 111-117. ISSN 1010-2752.
A 21 year old vineyard (Vitis vinifera L. cv. Aramond) showed symptoms similar to those caused by the root knot nematodes (Meloidogyne spp.) as well as decreases in yield. In a visit to the area, several chlorotic plants with different degree of defoliation were observed. The stem bases above the soil surface were swollen and they showed longitudinal cracks. Galls of different sizes were observed on the roots with significant losses of secondary roots. Adult females of Meloidogyne with well developed egg masses were found inside the galls. The study of the perineal patterns of these females showed the presence of specimens belonging to three species (Meloidogyne arenaria (Neal) Chitwood, Meloidogoyne incognita (Kofoid & White) Chitwood and Meloidogyne javanica (Trueb) Chitwood), as well as others that were grouped as Meloidogyne spp. until completing the molecular studies of all the specimens observed. M. arenaria showed to be the majority component of the community with 53%, followed by M. incognita and M. javanica with 21% and 4% respectively. The presence of M. arenaria in grapevine is the first report of this specie in the crop in Cuba and constitutes a focus of attention for the plant protection service because it is one of the most important pests in grapevine in the world.
