| 摘 要： | 目的]探讨伊维菌素和阿维菌素对中华鰟鮍(Rhodeus sinensis Gunther)的急性毒性效应。方法]采用急性毒性试验方法测定了伊维菌素、阿维菌素2种常见杀虫药对中华鰟鮍的半致死浓度(LC50)及安全浓度。结果]含量为6%的伊维菌素对中华鰟鮍的24、48、72、96 h LC50分别为71.68、45.04、37.81、35.69μg/L,安全浓度为0.001 3μg/L;含量为1%的阿维菌素对中华鰟鮍的LC50分别为129.35、77.35、47.54、34.63μg/L,安全浓度为0.000 2μg/L。结论]中华鰟鮍对伊维菌素和阿维菌素2种大环内酯类杀虫药较敏感,在使用过程中要注意用量,否则极易出现药害。

| Abstract: | Objective] The aim was to discuss the acute toxicity of ivermectin and avermectin on Rhodeus sinensis.Method] The LC50 and safety concentration of ivermectin and avermectin on R.sinensis in fresh water were investigated.Result] The LC50 of ivermectin with concentration of 6% against R.sinensis at 24,48,72 and 96 h were 71.68,45.04,37.81 and 35.69 μg/L respectively,and the safe concentration was 0.001 3 μg/L.The LC50 of avermectin with concentration of 1% against R.sinensis at 24,48,72 and 96 h were 129.35,77.35,47.54 and 34.63 μg/L respectively,and the safe concentration was 0.000 2 μg/L.Conclusion] R.sinensis was very sensitive to insecticides of ivermectin and avermectin.It indicated that it must be caution of ivermectin and avermectin injury on R.sinensis. |
