dc.descriptionThis document deals with the integrated management of the Black Weevil Rhynchophorus palmarum Linnaeus in the oil palm crop Elaeis guineensis Jacq. The objectives were to detail the symptoms and damage caused by the black weevil in the oil palm crop and to establish the integrated management methods of the black weevil R. palmarum in the oil palm crop E. guineensis. The conclusions determined that the external symptoms of infested palms include a progressive yellowing of the leaf area, damage to emerging leaves and necrosis in the flowers. The presence of internal galleries, as well as the deterioration of leaves and stems caused by larvae, can be easily identified in plants with a high degree of infestation. Damaged plant tissues emit strong and characteristic odors. Despite frequent attempts, chemical control of the insect is not successful. The cultural practice of burning affected trees reduces infestation levels. The most commonly used control methods are based on the capture of adults using traps baited with decomposing plant materials, such as palm tissue. Several types of traps have been proposed to attract insects and subsequently eliminate them by applying chemicals such as trichlorfon and ethyl pirimiphos. It is observed that yellow traps show greater effectiveness compared to those of different colors. Newer versions of the trap incorporate natural or synthetic aggregation pheromones to enhance insect attraction.es_ES

dc.description.abstractEl presente documento trata sobre el manejo integrado del Picudo negro Rhynchophorus palmarum Linnaeus en el cultivo de palma aceitera Elaeis guineensis Jacq. Los objetivos planteados fueron detallar la sintomatología y daño que causa el picudo negro en el cultivo de palma aceitera y establecer los métodos de manejo integrado del picudo negro R. palmarum en el cultivo de palma aceitera E. guineensis. Las conclusiones determinaron que los síntomas externos de las palmas infestadas incluyen un color amarillento progresivo del área foliar, daño a las hojas emergentes y necrosis en las flores. La presencia de galerías internas, así como el deterioro de hojas y tallos causado por las larvas, puede ser fácilmente identificado en plantas con un alto grado de infestación. Los tejidos de las plantas dañadas emiten olores fuertes y característicos. A pesar de los frecuentes intentos, el control químico del insecto no tiene éxito. La práctica cultural de quemar árboles afectados reduce los niveles de infestación. Los métodos de control más comúnmente empleados se basan en la captura de adultos mediante trampas cebadas con materiales vegetales en descomposición, como tejido de palma. Se han propuesto varios tipos de trampas para atraer insectos y posteriormente eliminarlos mediante la aplicación de sustancias químicas como triclorfón y etil pirimifos. Se observa que las trampas de color amarillo muestran mayor eficacia en comparación con aquellas de distintos colores. Las versiones más recientes de la trampa incorporan feromonas de agregación naturales o sintéticas para mejorar la atracción de insectos.es_ES
