| dc.description | Red Ring disease, caused by the nematode Bursaphelenchus (Rhadinaphelenchus) cocophilus and transmitted by the American palm weevil, Rhynchophorus palmarum, has been considered the most important disease of the coconut and oil palm in tropical America, and is still common today. in some plantations. The progress of the symptoms can be very rapid (acute form), and the affected palm can die within a few months after the first ones appear (progressive 'yellowing' and drying of the leaves starting with the oldest ones). At the other end of a continuum of symptoms, the younger leaves emerge short and with various types of malformations, but the plants may not die for several years (chronic form). The incidence of the disease can be kept at a low level, if an integrated management strategy is followed, which includes the early elimination of the inoculum sources (diseased palms), the destruction of the vector reproduction sites and the reduction of the adult population. Other diseases also affect oil palm in tropical America, but are usually of less economic impact. The present study aimed to compile information on the management of the Bursaphelenchus cocophilus nematode that causes the disease called “Red Ring” in the Oil Palm, describe the strategies used by the Palm Growers and evaluate the protocol established for the control of the disease, the agent causal and management protocols, with the purpose that the results admit knowing conclusions in order to propose alternatives that allow controlling the incidence of the same. | es_ES |

| dc.description.abstract | La enfermedad del “Anillo Rojo”, causada por el nematodo Bursaphelenchus (Rhadinaphelenchus) cocophilus y transmitida por el picudo americano de las palmas, Rhynchophorus palmarum, ha sido considerada la enfermedad más importante del cocotero y la palma aceitera en América tropical, y todavía hoy es común en algunas plantaciones. El progreso de los síntomas puede ser muy rápido (forma aguda), y la palma afectada puede morir en unos pocos meses después que aparecen los primeros (“amarillamiento” progresivo y secamiento de las hojas empezando por las más viejas). En el otro extremo de un continuo de síntomas, las hojas más jóvenes emergen cortas y con varios tipos de malformaciones, pero las plantas pueden no morir en varios años (forma crónica). La incidencia de la enfermedad puede ser mantenida a un bajo nivel, si se sigue una estrategia de manejo integrado, la cual incluye la eliminación temprana de las fuentes de inóculo (plantas enfermas), la destrucción de los sitios de reproducción del vector y la reducción de la población adulta. Otras enfermedades también afectan la palma aceitera en América tropical, pero normalmente son de menor impacto económico. El presente estudio tuvo como objetivo copilar información sobre el manejo del nematodo Bursaphelenchus cocophilus causante de la enfermedad denominada “Anillo Rojo” en la palma aceitera, describir las estrategias utilizada por los Palmicultores y evaluar el protocolo establecido para el control de la enfermedad, el agente causal y los protocolos de manejo, con la finalidad de que los resultados admitan conocer conclusiones para de esta forma plantear alternativas que permitan controlar la incidencia de la misma. | es_ES |
