Zusammenfassung:World-wide the chili pepper crop is affected by more than 60 viral diseases, although very little is known about them in the area of dry pepper plantation in northern-central Mexico. Consequently, the aims of this work were to identify the presence of the virus and the associated symptoms in commercial dry pepper fields of the states of Zacatecas, San Luis Potosí, and Aguascalientes, Mexico. Mirasol and ancho pepper plants were sampled and the presence of symptoms such as dwarfing, chlorosis, leaf deformation, defoliation, vascular necrosis and joined branches, were recorded. Samples were analyzed using DAS-ELISA with the antisera of the tobacco mosaic virus (Tobacco mosaic virus: TMV), cucumber mosaic virus (Cucumber mosaic virus: CMV), potato virus Y (Potato virus Y: PVY), pepper mottle virus (Pepper mottle virus: PepMoV), and tobacco etch virus (Tobacco etch virus: TEV). These viruses were identified in pepper plants collected in dry pepper fields located in the three states mentioned earlier A nivel mundial el cultivo de chile es afectado por más de 60 enfermedades virales; sin embargo, poco se conoce acerca de ellas en el área productora de chile seco del norte centro de México por lo que el objetivo del presente trabajo consistió en detectar la presencia y sintomatología de cinco virus en parcelas comerciales de chile seco en los estados mencionados. Plantas de chile de los tipos mirasol y ancho fueron muestreadas y se anotó la presencia de síntomas como enanismo, clorosis, deformación de hojas, defoliación, necrosis vascular y ramas unidas. Las muestras fueron analizadas mediante la técnica DAS-ELISA empleando los antisueros para el virus del mosaico del tabaco (Tobacco mosaic virus: TMV), mosaico del pepino (Cucumber mosaic virus: CMV), Y de la papa (Potato virus Y: PVY), moteado del chile (Pepper mottle virus: PepMoV) y jaspeado del tabaco (Tobacco etch virus: TEV). Esos virus fueron identificados en plantas de chile colectadas en las parcelas comerciales de chile seco de los tres estados antes mencionados
