El manejo del cultivo de la quinua y cañihua es necesaria debido a que fitoparásitos como los nematodos atacan sin dar señales de sintomatología, en tanto pueden llegar a impedir el paso de nutrientes y el normal crecimiento de la planta. En la región de Puno el género Globodera spp. es el que ocasiona más pérdidas, tanto para la quinua como para la cañihua, no entanto no existen reportes para Meloidogyne spp. siendo por ello los siguientes objetivos: Identificar los diferentes géneros de nemátodos fitoparásitos en los cultivos de quinua y cañihua en las principales zonas de producción de la región de Puno; estimar la densidad poblacional de los géneros de nemátodos fitoparásitos en los cultivos de quinua y cañihua; verificar la resistencia y/o susceptibilidad de variedades de quinua y cañihua al nemátodo del nodulo de la raíz (Meloidogyne spp.) en invernadero.

Phytoparasites such as nematodes attack without showing signs of symptoms, while they can prevent the passage of nutrients and the normal growth of the plant. In the region of Puno, the genus Globodera spp. is the most important pest, however there are no reports for Meloidogyne spp. Thus, the objective of this research is to identify the different genera of phytoparasite nematodes in the cultivation of quinoa in the main production areas of the Puno region. Soil samples were collected in the provinces of Puno, Huancané, San Román, Chucuito, Collao, Yunguyo and Azángaro. Nematode extraction from soil samples was carried out by the centrifugal fluctuation method with sucrose and mounted on permanent sheets for morphological studies.The genera of phytoparasite nematodes identified were Meloidogyne spp., Nacobbus spp., Pratylenchus spp.,&...
