          Abstract

          Los ambientes forestales de zonas de vida secas y muy secas del Caribe colombiano han sido profundamente impactados y a la fecha quedan muy pocos remanentes y rastros de su dinámica biológica original; por ello, en esta investigación se planteó estudiar la estructura y la variación estacional de los escarabajos fitófagos (Coleoptera: Scarabaeidae) en la Reserva Campesina La Montaña. Se realizaron 9 muestreos, desde enero hasta septiembre de 2011, y se instalaron 4 trampas de luz (2 BL y 2 WL) entre las 18:00 y las 24:00 h. Se capturaron 3,007 individuos y 18 especies agrupados en 3 subfamilias: Rutelinae (7 especies), Melolonthinae (6 especies) y Dynastinae (5 especies); sobresalió Melolonthinae con la mayor abundancia (2,907 individuos), y Liogenys quadridens fue la especie más abundante (1,667 individuos), reconocida por ser una plaga de cultivos semestrales, de amplia distribución en el Caribe colombiano. La mayor riqueza (16 especies) se observó en mayo y la mayor abundancia (1,421), en abril, lo que coincidió con la época de las primeras lluvias en la región, lo que pone de manifiesto una marcada estacionalidad que quedó demostrada con el análisis de similitud Anosim (R = 0.277, p < 0.003).

          Translated abstract

          Dry forests areas in the Caribbean region of Colombia have been deeply impacted lagging far precious few remnants and traces of its original dynamics, so the objective of this research is to study the structure and seasonality variation of phytophagous scarab beetles (Coleoptera: Scarabaeidae) in the Reserva Campesina La Montaña. Nine samples were obtained from January to September 2011. Four points distanced approximately 150 m were marked. In each one, a light trap was settled, for a total of 4 (2 white and 2 violet) operating since 18:00 until 24:00 h. 3,007 individuals and 18 species clustered in 3 subfamilies were collected: Rutelinae (7 species), Melolonthinae (6 species) and Dynastinae (5 species). Melolonthidae were the most abundant and Liogenys quadridens its most abundant specie (1,667 individuals), characterized by an important pest of semestral crops, and wide distribution in the Colombian Caribbean. The highest richness (16) was obtained in May, while April presented higher abundance (1,421), which coincides with the beginning of the rainy season, showing a marked seasonality showed by the analysis of similarity Anosim (R = 0.277, p < 0.003).
