Helicotylenchus

El golf es una importante actividad turística del estado de Baja California Sur (SECTUR, 2019) Una de las problemáticas que pueden demeritar su calidad y estética es la presencia de síntomas de marchitez y amarillamiento (Figura 1). Este daño puede estar asociado a diferentes factores bióticos y abióticos. Dentro de éstos, destaca la presencia de nematodos fitopatógenos como el nemátodo espiral (Helicotylenchus spp.), el cual se considera uno de los problemas que afecta el césped en campos de golf de todo el mundo.

Summary The distribution and community structure of plant-parasitic nematodes associated with betel (Piper betle) vine and their relationship with soil chemical properties were investigated in four major growing regions of West Bengal, India. Ordinary kriging method was applied to infer the patterns of spatial distribution of major plant-parasitic nematodes across the growing regions. Meloidogyne and Rotylenchulus were found to be the most abundant genera in betel vine crops in all growing regions. Co-inertia analysis between soil properties and nematode abundance indicated that soil chemical characters significantly affect abundances of plant-parasitic nematodes. The type of betel vine crop (sweet and bitter) also has a significant effect on the abundance of plant-parasitic nematodes, with the highest abundance of Meloidogyne reported from the bitter type of betel crop. Spatial distribution depicted a higher abundance of Meloidogyne throughout the North Bengal growing region. Root-...
