 es Efecto de Ontherus sulcator check for this species in other resources F. (Coleoptera : Scarabaeidae) en la incorporación de estiércol al suelo
Pedro Mariategui, Claudio Speicys, Néstor Urretabizkaya y Eduardo Fernández

Resumen

La acumulación de estiércol en los campos de la cuenca del Río Salado trae aparejado el problema de pérdida de área de pastoreo, nutrientes al suelo y un aumento en la acumulación de parásitos. En el estiércol existe una entomofauna que resulta potencialmente benéfica para evitar los problemas mencionados. Dentro de dicha entomofauna encontramos escarabajos coprófagos y coprófilos, de los cuales se destaca por su abundancia y su actividad Ontherus sulcator check for this species in other resources F. (Coleóptero Scarabeidae). Con el objetivo de estudiar la importancia de este insecto en la incorporación de bosta al suelo, se realizó un ensayo con 24 recipientes con tierra y un Kg de estiércol. A 18 de éstos se les agregó 20 escarabajos por balde y al cabo de 7 días se procedió a pesar el estiércol remanente de cada balde. Se empleó el test t de Student para comparar las medias de ambos grupos, arrojando diferencias altamente significativas (P < 0,001). Este resultado sugiere que Ontherus sulcator F. es un potencial aliado para el productor de la Cuenca del Río Salado, por la particularidad de tener como sustrato para su alimentación y la de su descendencia a las deposiciones bovinas, acelerando la desaparición de las bostas de la superficie del campo.

 en Ontherus sulcator check for this species in other resources F. (Coleoptera:Scarabaeidae) effect in the incorporation of dung from the soil

Abstract

Dung accumulation along the drainage area of Salado River leads to the problem of loss of areas dedicated to cattle feeding, as well as the loss of soil nutrients, and an increasing accumulation of parasites. There exists an entomofauna which proves to be potentially benefic for the elimination of pollution in the fields and for the prevention of cattle parasites. Among the entomofauna, we find coprophagous (dung-eating) and coprophylous scarabs, being Ontherus sulcator check for this species in other resources F. (Coleoptera Scarabaeidae) the most abundant and active. With the purpose of studying the importance of this insect in the incorporation of dung into the soil, a test was carried out with 24 recipients filled with soil and 1 kg of dung. 20 scarabs per bucket were added to 18 of these recipients and after 7 days the remaining dung of each bucket was weighted. The Student t test was used in order to compare the measures in both groups. The results showed highly significant differences (P<0.001). From this result we understand that Ontherus sulcator F. ( Coleoptera Scarabaeidae) is a potential ally for the farmer of the Salado River drainage area, because it has a very particular feature. It makes use of the bovine defecation as a substratum for its own feeding and for its descendants, causing the dung to disappear quickly from the field surface.
