“…We observed increased mortality dependent on concentration and duration of exposure. Similarly, acute toxicity tests of deltamethrin and cypermethrin in embryos and larvae of common carp have shown concentration-dependent decreases in hatching success (Koprucu and Aydin 2004;Aydin et al 2005).…”

ABSTRACT:The aim of this study was to assess the effects of Cyperkill 25 EC (a.i. cypermethrin 250 g/l) on cumulative mortality, growth indices, and ontogenetic development of embryos and larvae of common carp (Cyprinus carpio L.). An early-life stage toxicity test was used. Liver, intestine, kidneys, and gills of surviving larvae were examined, and the activity of the detoxifying and antioxidative enzymes glutathione reductase (GR), glutathione peroxidase (GPx), catalase (CAT), glutathione-S-transferase (GST), as well as lipid peroxidation (TBARS) was determined. Eggs of common carp 24 h post-fertilisation were exposed for 35 days to Cyperkill 25 EC at concentrations of 7.2, 36, 72, 144, and 360 μg/l containing the active ingredient cypermethrin at concentrations of 1.8, 9, 18, 36, and 90 μg/l, respectively. All larvae exposed to concentrations higher than 144 μg/l showed signs of damage after five days and died in the next two days; at concentrations of 72 and 36 μg/l total mortality was observed several days after hatching. Larvae exposed to 7.2 μg/l survived to the end of the test but showed significantly lower growth (P < 0.01) and retarded ontogenetic development compared to controls. Examination of these larvae did not reveal histological changes. Activity of GST, GR, and GPx in the exposed group was significantly lower (P < 0.01), while CAT and TBARS did not show significant differences from controls. Exposure to Cyperkill 25 EC affected hatching and survival at tested concentrations above 7.2 μg/l. Alterations in oxidative stress parameters and retarded growth and ontogenetic development were evident at 7.2 μg/l.

“…En especial los peces tienen ciertas deficiencias enzimáticas para hidrolizar los piretroides, además su sistema nervioso es muy sensible y tienen una baja capacidad de metabolizar y eliminar insecticidas (Bradbury et al 1986, Viran et al 2003, Aydin et al 2005.…”

Palabras clave: acuacultura, insecticidas, peces, CL50, dengue, ecotoxicología RESUMENLa tilapia Oreochromis niloticus es una especie de importancia en acuacultura con un desarrollo promisorio en la península de Yucatán. La bifentrina y la deltametrina son dos piretroides ampliamente utilizados por el sector salud en Yucatán para el control del mosquito Aedes aegypti, vector del dengue. Se evaluó la toxicidad aguda diferencial de Talstar® (sustancia activa, bifentrina) y Biothrine® (principio activo, deltametrina), en juveniles de tilapia O. niloticus. Se usaron ocho concentraciones de Talstar® (2.5 -400 µg/L) y ocho concentraciones de Biothrine® (0.56 -112 µg/L), más un testigo sin insecticida y tres repeticiones por tratamiento. Los signos de toxicidad en los peces bajo la influencia de ambos insecticidas fueron: nadadas erráticas, desbalance e hiperventilación, aunque resultaron más evidentes y en un menor tiempo de aparición, en las concentraciones más altas. El análisis probit reveló que la concentración letal media (CL50) de Talstar® fue de 75.11 µg/L a las 96 horas con intervalos de confianza (95 %) de 58.76 (inferior) y 96.34 (superior) µg/L. La CL50 de Biothrine® fue de 28.36 µg/L a las 96 horas, con intervalos de 23.29 y 35.27 µg/L. Estos valores son considerados como extremadamente tóxicos y alertan por el efecto contaminante potencial que podrían producir en ambientes naturales y de acuacultura. Es necesario continuar con la evaluación de los mecanismos de toxicidad de insecticidas que son utilizados en el sector salud para especies de importancia acuícola en México. Lo anterior por la perspectiva de continuar con su empleo y por el desarrollo del sector en la península de Yucatán.Key words: aquaculture, insecticides, fishes, LC50, dengue, ecotoxicology ABSTRACT Tilapia, Oreochromis niloticus is an aquacultural important species and both, bifenthrin and deltamethrin are two synthetic pyrethroids used by Health Services in Yucatán to control Aedes aegypti mosquito, dengue's vector.

“…Such insecticides tend to be toxic to ϐish and other aquatic organisms. Several products containing Pyrethroids are classiϐied as 'limited use pesticides', by the Environmental Protection Agency, due to their toxicity to ϐish (Aydin et al 2005, Saha & Kaviraj 2009.…”

Pyrethroid toxicity in silver catfish, Rhamdia quelen

This study aimed to determine both the lethal and sublethal concentrations of Cypermethrin in young Silver Catϐish (Brazilian "Jundiá", Rhamdia quelen) on aquatic environment during 96 hours, as well as to determine the Cypermethrin and Deltamethrin sublethal concentrations during the initial embryonic development period of Rhamdia quelen, and to verify their respective rates of fertilization, hatching and survival. Pyrethroid nowadays is a widely used insecticide, which presents a high toxicity to ϐish. In order to determine lethal and sublethal concentrations, 120 silver catϐish were used; each one had an average weight of 59.58±4.50g and an average size of 20.33±2.34cm. Concentrations used were 0, 1.0, 1.5, 2.0, 2.5, 3.0, 5.0, 10.0, 15.0 and 20.0mg of Cypermethrin per liter of water (mg/L). Fish were exposed to the product in 30-liter ϐish tanks. In each ϐish tank there were four ϐishes and the product was applied three times, i.e., a total of twelve ϐish were exposed to the product at each application, and a total of 120 ϐish during the entire experiment (n=120). In order to determine the Cypermethrin and Deltamethrin sublethal concentrations during the initial embryonic development, ovulation induction was performed on female ϐishes using hormones, and then and egg collection was performed. The eggs were then hydrated and fertilized in Cypermethrin and Deltamethrin in different concentrations: 0.001, 0.01, 0.1, 1.0 and 10.0mg/L of Cypermethrin and 0.001, 0.01, 0.1, 0.5 and 1.0mg/L of Deltamethrin, in addition to the control group (0mg/L). After fertilization, the eggs were kept in containers with the respective pesticides of Cypermethrin and Deltamethrin until hatching, when hatching rate was veriϐied. Then the alevins, from the hatching, were kept on their respective concentrations of Cypermethrin and Deltamethrin so that the survival rate could be analyzed regarding the tested insecticides, during both 12-hour and 24-hour periods. Concerning the sublethal and lethal concentrations, Silver Catϐish was sensitive to the tested concentrations of Cypermethrin, showing symptoms of poisoning, such as loss of balance, swimming alteration, dyspnea (they kept their mouths and opercula open), upright swimming and sudden spiral swimming movements. The intensity of such symptoms varied in proportion to the concentration used. The concentrations above 3.0mg/L were considered lethal to the species, since every animal exposed to concentrations between 3.0 and 20.0mg/L had died, while concentrations between 1.0 and 2.5mg/L were considered sublethal. Deltamethrin during the initial embryonic development, the results show that both pyrethroids had signiϐicantly decreased the analyzed parameters when comparing them with the control group. It was concluded that, even with the ϐish being more resistant to pyrethroids in comparison with other species, both the young animals and the ones in stage of embryonic development were susceptible to the effects of these pesticides. Para determinação da concentração letal e subletal foram...
