Manejo integrado de los principales Chrysomelidae defoliadores en el cultivo de la Soja

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.
