El maíz (Zea mays L.) es un cereal de importancia mundial por sus diferentes usos industriales y valor nutritivo. Al igual que otros cultivos, se ve afectado por plagas, entre ellos los nematodos fitoparásitos, principalmente del género Meloidogyne, cuya presencia ocasiona disminución en los rendimientos, por ello se plantea como objetivo principal del presente trabajo de investigación caracterizar al “nematodo del nódulo de la raíz” en el cultivo de maíz en las regiones de Puno y Cusco, también se planteó identificar los géneros de nematodos fitoparásitos asociados al maíz en las principales zonas de producción de las regiones de Puno y Cusco, determinar la variación de la densidad poblacional de los nematodos fitoparásitos encontrados en el cultivo de maíz de las principales zonas de producción de las regiones de Puno y Cusco y verificar la resistencia de razas de...

Corn (Zea mays L.) is a cereal of global importance for its different industrial uses and nutritive value. Like other crops, it is affected by pests, including nematodes, whose presence in the maize crop causes a decrease in yields, so the present work is presented. In order to determine the population density of nematodes associated with maize cultivation in the regions of Puno and Cusco; For which 121 soil samples were collected during the 2015-2016 campaign in the Puno Region, in the districts of Chupa, Sandia, San Juan del Oro, Cuyocuyo, Ayapata, Ollachea and San Gabán; And 30 samples from the Cusco Region, in the districts of Pisac and Urubamba. Were identified the genera genera Helicotylenchus spp. and verified. (32-100%), Mesocriconema spp. (33.3-63.8%), Globodera spp. (96-100%), Xiphinema spp. (11-36.6%), Rotylenchus spp. (2...
