          Abstract

          Se evaluó el impacto ecotoxicológico del insecticida carbámico cartap (1,3 di (carbamoytio)-2-dimetiloaminopropano) usado para el control de plagas agrícolas y como molusquicida de vectores de importancia en Salud Pública, sobre dos especies de peces del ecosistema acuático continental: Poecilia reticulata (Peters 1859) "guppy" (Poecilidae) y Paracheirodon innesi (Myers 1936) ``Neon Tetra" (Characidae). Ellos fueron utilizados como organismos no destinatarios en ensayos de corta duración, para determinar el impacto toxicológico del cartap. Para ambas especies de peces se evaluó el porcentaje de mortalidad, y dos respuestas subletales: el incremento del movimiento opercular y el nado extraño. A 3 h de exposición para P. reticulata, se encontró un valor de CL50 (Concentración letal media) de 6,75 mg•L-1 y valores de CE50 (Concentración efectiva media) de <7,55 y < 8,16 mg•L-1 para el incremento del movimiento opercular y nado extraño, respectivamente. Para P. innesi, se encontró un valor de CL50 de <0,02 mg•L-1 y valores de CE50 de < 0,01 y < 0,03 mg•L-1, para el incremento del movimiento opercular y nado extraño, respectivamente. P. innesi fue más sensible al cartap que P. reticulata. Se calculó los cuocientes de riesgo (RQ) para la evaluación del riesgo ambiental (ERA) de este insecticida sobre el ecosistema acuático, indicando que P. innesi es más adecuada que P. reticulata como herramienta ecotoxicológica para evaluar cartap.

          Translated abstract

          The ecotoxicological impact of the carbamate insecticide cartap (1,3 di (carbamoythio)-2-dimethyloaminopropan) used for agriculture pests and as mollusquicide of vectors of Public Health importance was evaluated, on two fish species of the continental aquatic ecosystem. Poecilia reticulata (Peters 1859) ``guppy" (Poecilidae) and Paracheirodon innesi (Myers 1936) ``Neon Tetra" (Characidae) were employed as non-target organisms in assays of short duration to determine the toxicological impact of cartap. For both fish, percentage of mortality and two sublethal responses: increase of opercula movement and strange swim, were evaluated. In P. reticulata after 3 h exposure it was found a LC50 (mean Lethal Concentration) of 6.75 mg'•L-1 and values of EC50 (mean Effective Concentration) of <7.55 and <8.16 mg•L-1 as speed up of opercula movement and strange swim, respectively. For P. innesi, it was found an LC50 value of <0.02 mg•L-1 and values of EC50 of <0.01 and <0.03 mg•L-1, as speed up of opercula movement and strange swim, respectively. P. innesi was more sensitive to cartap than P. reticulata. Risk Quotients (RQ) to evaluate environmental risk (ERA) of this insecticide on aquatic ecosystem were calculated, indicating that P. innesi was more accurate than P. reticulata as ecotoxicological tool to evaluate cartap.
