| dc.description | The pink bollworm, Pectinophora gossypiella, is one of the most destructive pests of cotton in tropical and subtropical regions of the world. The objective of the research was to explain the management of the Pink Bollworm P. gossypiella in cotton cultivation. The document was prepared through the compilation of information from scientific articles, theses, sources and bibliographic repositories that are considered scientific sources accessible through digital platforms. The results indicate that the damage caused by the pink bollworm P. gossypiella. This is because the larvae burrow into the surface of the inner wall of the acorn. Alternatives to control the pink bollworm in cotton cultivation include: defoliation of crops, desiccation of the crop at the end of the season, elimination of immature bolls at the end of the vegetative cycle and the implementation of varieties short cycle and the method of greatest control consists of carrying out periodic sampling in the plots. The conclusions determined that when the larvae emerge from the eggs they cause damage when feeding. They eat the fibers and seeds. Thus they cause damage to the production of cotton and the oil, which is harvested from the seeds. In turn, they cause the introduction of other pests and pathogens such as insects and fungi. There are alternatives such as cultural control (shredding stems, incorporation of stubble into the soil, maintaining a sanitary vacuum, applying irrigation, appropriate sowing dates and rotations with grasses), biological (botanical insecticide produced from Neem), ethological (traps with pheromones ) and chemical (thiodicarb, profenofos, quinalfos or chlorpyrifos). The greatest control method used against P. gossypiella consists of carrying out periodic sampling in the most advanced plots (with receptive fruits), with the aim of verifying the presence or absence of larvae inside the capsules. | es_ES |

| dc.description.abstract | El gusano rosado de la cápsula, Pectinophora gossypiella es una de las plagas más destructivas del algodón en las regiones tropicales y subtropicales del mundo. El objetivo de la investigación fue explicar el manejo del Gusano Rosado de la Cápsula Pectinophora gossypiella en el cultivo de algodón. El documento se elaboró a través de la recopilación de información proveniente de artículos científicos, tesis, fuentes y repositorios bibliográficos que sean considerados fuentes científicas accesibles a través de plataformas digitales. Los resultados indican que los daños que causa el gusano rosado de la cápsula P. gossypiella. se debe a que las larvas excavan la superficie de la pared interna de la bellota. Las alternativas de control del gusano rosado de la cápsula en el cultivo de algodón se incluyen: la defoliación de los cultivos, la desecación de la cosecha al concluir la temporada, la eliminación de las cápsulas inmaduras al final del ciclo vegetativo y la implementación de variedades de ciclo corto y el método de mayor control consiste en efectuar muestreos periódicos en las parcelas. Las conclusiones determinaron que cuando las larvas emergen de los huevos causan daño al alimentarse. Comen las fibras y las semillas. Así causan daño a la producción de algodón y del aceite, que es cosechado de las semillas. A su vez son causa de la introducción de otras plagas y patógenos como insectos y hongos. Existen alternativas como control cultural (triturar tallos, incorporación al suelo de los rastrojos, mantener el vacío sanitario, aplicar riegos, fechas de siembra adecuadas y rotaciones con gramíneas), biológico (insecticida botánico producido a partir de Neem), etológico (trampas con feromonas) y químico (tiodicarb, profenofos, quinalfos o clorpirifos). El método de mayor control usado contra P. gossypiella consiste en realizar muestreos periódicos en las parcelas más adelantadas (con frutos receptivos), con el objetivo de constatar la presencia o no de larvas dentro de las cápsulas. | es_ES |
