  • Flusilazole has a broad-spectrum germicidal efficacy to curb diseases caused by basidiomycetes and hemispheres.Chirocephalus is a salt tolerant small crustacean, which is used as live food for finfish and shellfish in aquaculture. In recent years it is used as a model organism to evaluate the environmental safety of pesticides. The effective concentration(EC50) of flusilazole against the Chirocephalus was determined by using an acute toxicity test after 38 h flusiazole exposure. Activities of superoxide dismutase（SOD） and peroxidase（POD） in the Chirocephalus were tested with an enzyme activity kit, and mamondialdehyde（MDA） content was tested by using the thiobarbituric acid（TBA） method after 38 h flusiazole exposure. The results showed that the EC50 of flusilazole to the Chirocephalus was 5.228 mg·L-1, which was of moderate toxicity. The hatching rate of the Chirocephalus was significantly decreased with an increase in concentration of flusilazole, as compared with that of the control. The toxic effects of flusilazole may cause oxidative stress in Chirocephalus. The activities of SOD and MDA content were increased, and the POD activity was decreased in all the treatment groups, compared with the control.

Abstract: Flusilazole has a broad-spectrum germicidal efficacy to curb diseases caused by basidiomycetes and hemispheres.Chirocephalus is a salt tolerant small crustacean, which is used as live food for finfish and shellfish in aquaculture. In recent years it is used as a model organism to evaluate the environmental safety of pesticides. The effective concentration(EC50) of flusilazole against the Chirocephalus was determined by using an acute toxicity test after 38 h flusiazole exposure. Activities of superoxide dismutase（SOD） and peroxidase（POD） in the Chirocephalus were tested with an enzyme activity kit, and mamondialdehyde（MDA） content was tested by using the thiobarbituric acid（TBA） method after 38 h flusiazole exposure. The results showed that the EC50 of flusilazole to the Chirocephalus was 5.228 mg·L-1, which was of moderate toxicity. The hatching rate of the Chirocephalus was significantly decreased with an increase in concentration of flusilazole, as compared with that of the control. The toxic effects of flusilazole may cause oxidative stress in Chirocephalus. The activities of SOD and MDA content were increased, and the POD activity was decreased in all the treatment groups, compared with the control.
