Effects of chlorpyrifos on life cycle parameters, cytochrome P450S expression, and antioxidant systems in the monogonont rotifer Brachionus koreanus
Courtesy of John Wiley & Sons, Ltd.
Chlorpyrifos (CPF) is a widely used organophosphorus insecticide for controlling diverse insect pests of crops. In the monogonont rotifer Brachionus koreanus, population growth retardation with the inhibition of lifespan, fecundity, and individual body size of ovigerous females was shown over 10 d in response to CPF exposure. At the molecular and biochemical levels, the rotifer B. koreanus defensome composed by cytochrome P450 complements, heat shock protein 70, and antioxidant enzymatic systems (i.e., glutathione, glutathione peroxidase, glutathione reductase, and glutathione S‐transferase) was significantly induced in response to different concentrations of CPF. Thus, CPF strongly induced a defensome system to mitigate the deleterious effects of CPF at in vivo and in vitro levels as a trade‐off in fitness costs. This article is protected by copyright.
