description Fungi are part of the diet of larvae and adults of the order Coleoptera; however, it is a resource that is infrequently used as an attractant for the collection of these insects. In this work, mycetophilous beetle assemblages were analyzed in four localities located along an altitudinal gradient in the central region of Chiapas, Mexico. Pitfall traps baited with the fruiting body of the fungus Agaricus bisporus previously fermented were used for beetle sampling. A total of 208 individuals comprising 27 species of the families Scarabaeidae (Scarabaeinae), Silphidae, and Staphylinidae were captured. Species diversity was low compared to other attractants used for sampling these insect groups, however, a high representativeness of species was obtained. In general, diversity is related to increasing altitude, but the response was different among families. Scarabaeinae was better represented in the lower altitude sites, the opposite case occurred with Staphylinidae that predominated in the higher altitude sites, this allowed differentiation of three beetle communities along the gradient (Dβ = 2.77). Despite the low prevalence of species and their abundances, these results indicate that these types of attractants can be used by diverse species and are likely to function as an alternate source to segregate demand competition and food partition when preferred resources are scarce. Offering a diverse number of potential food resources would allow to establish the trophic spectrum of species in a more realistic and objective way. Therefore, this type of attractant can be used to capture beetles in biodiversity inventories allowing to obtain more accurate results on local insect diversity.

Los hongos son parte de la dieta de larvas y adultos del orden Coleoptera; sin embargo, es un recurso que con poca frecuencia se utiliza como atrayente para la recolección de estos insectos. En este trabajo se analizaron los ensamblajes de escarabajos micetófilos en cuatro localidades ubicadas a lo largo de un gradiente altitudinal de la región central de Chiapas, México. Para el muestreo de escarabajos se utilizaron trampas de caída cebadas con el cuerpo fructífero del hongo Agaricus bisporus previamente fermentado. En total se capturaron 208 individuos que integran 27 especies de las familias Scarabaeidae (Scarabaeinae), Silphidae y Staphylinidae. La diversidad de especies fue baja en comparación con otros atrayentes utilizados para el muestreo de estos grupos de insectos, no obstante, se obtuvo una alta representatividad de especies. De manera general, la diversidad está relacionada con el incremento de la altitud, pero la respuesta fue diferente entre familias. Scarabaeinae estuvo mejor representada en los sitios de menor altitud, caso contrario ocurrió con Staphylinidae que predominó en los sitios de mayor altitud, esto permitió diferenciar tres comunidades de escarabajos a lo largo del gradiente (Dβ = 2.77). A pesar de la baja prevalencia de especies y sus abundancias, estos resultados indican que este tipo de atrayentes pueden ser utilizados por diversas especies y es probable que funcionen como una fuente alterna que permite segregar la competencia por la demanda y la repartición de alimento cuando los recursos preferidos son escasos. Ofrecer un número diverso de recursos alimentarios potenciales, permitiría establecer el espectro trófico de las especies de forma más realista y objetiva. Por lo tanto, este tipo de atrayentes pueden ser utilizados para la captura de escarabajos en los inventarios de biodiversidad permitiendo obtener resultados más precisos sobre la diversidad local de insectos.
