Manejo del gusano rosado de la cápsula Pectinophora gossypiella Saunders, 1844 en el cultivo de algodón (Gossypium spp).

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.
