The genotoxic effect of the new acaricide etoxazole.
Etoxazole is a member of the diphenyl oxazoline class of insecticide was newly developed for use on pome fruits, cotton and strawberries as a acaricide. In the present study, genotoxic effects of acaricide etoxazole (ETX) (miticide/ovicide) were investigated using chromosome aberration (CA) test, sister chromatid exchange (SCE) test and micronucleus test in human lymphocytes. ETX induced the CAs at all concentrations (5, 10 and 20 microg/ml) for 24 h and also induced the CA at the highest concentration (20 microg/ml) for 48 h only. The inducing the CAs for 48 hours treatment period was dose-dependent. Besides, it induced the SCE at all concentrations and treatment periods in a dose-dependent manner as well. Although, ETX decreased the mitotic index (MI) at all concentration and treatment periods dose-dependently, while it did not decrease the replication index (RI) when compared to the negative and solvent controls. In addition, ETX induced the micronucleus at all concentrations except 5 microg/ml for 48 h. This inducing was in a dose-dependent manner as well. In conclusion, it can be concluded that ETX has a potential genotoxic effects in cultured human peripheral lymphocytes.
