| dc.description | The soybean crop (G. max) is of great economic and food importance, however, it faces significant threats from defoliators belonging to the Chrysomelidae family which, by attacking the leaves of soybean plants, can cause a variety of damages that directly affect plant health and yield. These insects feed on leaf tissue, leaving behind perforations, spots, and denuded areas of leaves. The objective of this work was to characterize the integrated management of the main defoliating Chrysomelidae in soybean. Accordingly, results documented in scientific sources were reviewed, thanks to which it was possible to highlight the serious threat posed by species such as Diabrotica speciosa, Cerotoma tingomariana, Cerotoma trifucarta and Cerotoma fascialis to soybean crops, negatively impacting yield and grain quality. Cultural, biological, ethological and chemical control methods are proposed to mitigate the damage caused by these insects, emphasizing the importance of applying them accurately at critical stages of the crop. Specific chemical insecticides such as cypermethrin or deltamethrin are commonly used, whose doses vary according to the concentration and severity of the pest, following the indications on the product label and applied when the level of economic damage is reached. The study seeks to develop effective and sustainable strategies to control these pests, promoting food safety and economic profitability in the agricultural sector. | es_ES |

| dc.description.abstract | El cultivo de soja (Glycine max L) es de gran importancia económica y alimentaria, sin embargo, enfrenta amenazas significativas por parte de los defoliadores pertenecientes a la familia Chrysomelidae que al atacar las hojas de las plantas de soja pueden causar una variedad de daños que afectan directamente la salud y el rendimiento de la planta. Estos insectos se alimentan del tejido foliar, dejando tras de sí perforaciones, manchas y áreas despojadas de hojas. Este trabajo tuvo como objetivo caracterizar el manejo integrado de las principales Chrysomelidae defoliadores en el cultivo de la soja. En función de esto, se revisaron resultados documentados en fuentes científicas, gracias a las cuales se pudo se logró destacar la grave amenaza que representan especies como Diabrotica speciosa, Cerotoma tingomariana, Cerotoma trifucarta y Cerotoma fascialis para los cultivos de soja, impactando negativamente en el rendimiento y calidad del grano. Se proponen métodos de control cultural, biológico, etológico y químico para mitigar los daños ocasionados por estos insectos, enfatizando la importancia de aplicarlos con precisión en las etapas críticas del cultivo. Se recurre comúnmente a insecticidas químicos específicos como cipermetrina o deltametrina, cuyas dosis varían según la concentración y severidad de la plaga, debiendo seguir las indicaciones de la etiqueta del producto y aplicarse cuando se alcanza el nivel de daño económico. El estudio busca desarrollar estrategias efectivas y sostenibles para controlar estas plagas, promoviendo la seguridad alimentaria y la rentabilidad económica en el sector agrícola. | es_ES |
