Abstract (en):
The dung beetle (Digitonthophagus gazella) has been introduced in different regions around the world with the purpose of contributing in dung removal and parasite control. This species has shown a high mobility rate and is recorded nowadays in the United States, Mexico, Guatemala, Nicaragua, several Caribbean islands, Colombia, Venezuela, Brazil, Peru, Bolivia, Argentina, and Paraguay. In Colombia it was reported for the first time in
San Andres Island in 1995 and in 2004 in the continental area. Since then, studies have been carried out in the Caribbean and Orinoquia regions, and Cauca, and Magdalena river valleys, to establish its dispersal process and to determine possible effects on native populations. The historic process of introduction and establishment is described. It is confirmed an increase in the distribution pattern and establishment of this species, and in addition, its effect on local populations is discussed, where a decrease in the abundance of native species have been registered. It is necessary to develop monitoring plans in the medium term in order to find control mechanisms.
Abstract (es):
El escarabajo coprófago (Digitonthophagus gazella), ha sido introducido en diferentes regiones del mundo con el fin de contribuir en la remoción del excremento y control de parásitos. Esta especie ha evidenciado una alta tasa de movilidad y se registra actualmente en Estados Unidos, México, Guatemala, Nicaragua, varias islas del Caribe, Colombia, Venezuela, Brasil, Perú, Bolivia, Argentina y Paraguay. En Colombia en 1995 se reportó por primera vez en la isla de San Andrés y en 2004 en el territorio continental. Desde entonces se han realizado estudios en la región del Caribe, Orinoquia, valles de los ríos Cauca y Magdalena, con el fin de establecer su proceso de dispersión y dimensionar los posibles efectos sobre las poblaciones nativas. Se describe el proceso histórico de introducción y establecimiento, se evidencia un incremento en la distribución y proceso de invasión de esta especie y se discute su efecto sobre poblaciones locales donde se han registrado disminuciones en las abundancias de las especies nativas. Es necesario generar planes de monitoreo a mediano plazo con el fin de encontrar mecanismos de control.
