          Abstract

          Este estudio describe la fauna de escarabajos estercoleros (Scarabaeidae: Scarabaeinae) en ranchos ganaderos del trópico subhúmedo. De enero a diciembre de 2010 se recolectaron 93 274 escarabajos estercoleros pertenecientes a 17 especies de la subfamilia Scarabaeinae con trampas de caída libre cebadas con excremento de ganado bovino en 4 ranchos ganaderos del oriente del estado de Yucatán, México. Las especies más abundantes fueron Onthophagus landolti, seguida por Canthon indigaceus chevrolati, Digitonthophagus gazella, C. leechi y Pseudocanthon perplexus. Se observó que las especies cavadoras tuvieron mayor abundancia y riqueza; las diurnas de talla pequeña tuvieron menor riqueza pero fueron más abundantes en todo el estudio. El conocimiento de la composición faunística de escarabajos estercoleros de la región es un punto de partida para desarrollar estudios del impacto de las actividades humanas y las prácticas de producción ganadera sobre la diversidad de estos insectos.

          This study describes the fauna of dung beetles (Scarabaeidae: Scarabaeinae) in tropical sub-humid cattle ranches. Insects were collected with pitfall traps baited with cattle manure from January to December 2010 in four cattle ranches of eastern state of Yucatán, Mexico. 93 274 dung beetles were collected from 17 species of the subfamily Scarabaeinae. The most abundant species were Onthophagus landolti, followed by Canthon indigaceus chevrolati, Digitonthophagus gazella, C. leechi y Pseudocanthon perplexus. Observations showed that burrowing species had greater abundance and species richness. Diurnal species of small size had lower richness, but were more abundant. Knowledge of the composition of dung beetle fauna of the region is a starting point to develop studies of the impact of human activities and livestock production practices on the diversity of these insects.
