| Abstract: | In order to eliminate chironomidae larvae from the juvenile foster pool,8 common aquatic insecticide including praziquantel,ivermectin,avermectin,fenvalerate were used to test the elimination effect on juveniles of Hyriopsis cumingii and chironomidae larvae.Then,acute toxicity experiment was conducted to the selected insecticide.On the basis of these outcomes,the drug application test of killing chironomid larvae at juvenile breeding stage was carried out.The results showed that deltamethrin was the best choice in killing chironomid larvae at juvenile H.cumingii breeding stage.Under the average water temperature of 27 ℃,the median lethal concentration(LC 50) of deltamethrin against juvenile and chironomid larvae at 48h and 96h were 3.150 mg/L,2.471 mg/L and 0.1044 mg/L,0.01851 mg/L,respectively.The safe concentration(SC) of deltamethrin against juvenile and chironomid larvae were 0.247 mg/L and 0.00185 mg/L,respectively.In juvenile foster pool,the effective concentration of deltamethrin to kill chironomid larvae and reduce the effect of physiological function in juvenile was 0.431~0.632 mg/L. |
