Joint toxicity of permethrin and cypermethrin at sublethal concentrations to the embryo-larval zebrafish

Effects of cypermethrin on survival, morphological and biochemical aspects of rohu (Labeo rohita) during early development

“…1). These findings are concordant with Yang et al (2014) who observed a dose and time dependent increase in mortality in Zebra fish embryo upon exposure to CYP exposure. Carriquiriborde et al (2009) also found an increase in mortality rate during the embryonic stages of Odontesthes bonariensis after exposing to 0.1e100 mg L À1 of CYP for 4 weeks.…”

“…The POD activity in the CYP treated group was also increased from 24 to 96 h compared to the control group where it decreased with the passage of time. Yang et al (2014) also reported elevation in the activities of CAT and SOD in zebrafish embryo in response to CYP and permethrin exposure. Similarly, Ullah et al (2014) found increased activity of CAT and POD in various tissues of Tor putitora after exposure to CYP.…”

Larvicidal activity of endophytic fungal extract of Cochliobolus spicifer (Pleosporales: Pleosporaceae) on Aedes caspius and Culex pipiens (Diptera: Culicidae)

“…This assay has since become the established zebrafish embryo test and is widely used in chemical screening as well as being recommended by the Organisation for Economic Co-operation and Development (OECD) (McGrath and Li 2008). Since insecticides are known to pose a potential threat to aquatic animals, various studies have utilized zebrafish embryos to evaluate toxicity related to these insecticides (Chandrasekar et al 2011;Lopez-Romero et al 2012;Mizell and Romig 1997;Osterauer and Kohler 2008;Pandey and Guo 2014;Shi et al 2011;Xu et al 2014;Yang et al 2014).…”

TOXICIDAD AGUDA DIFERENCIAL DE TALSTAR® (BIFENTRINA) Y BIOTHRINE® (DELTAMETRINA) EN LA TILAPIA NILÓTICA Oreochromis niloticus

“…Los piretroides producen baja toxicidad en mamí-feros y aves, pero en los peces se presenta una mayor susceptibilidad, debido a un desequilibrio entre una alta tasa de absorción branquial y una baja detoxificación hidrolítica (Yang et al 2014). 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.…”
