采用半静水试验法，研究了敌百虫、氯氰菊酯和阿维菌素等3种抗寄生虫药物对方斑东风螺（Babylonia areolata）稚螺的急性毒性。结果表明，敌百虫、氯氰菊酯和阿维菌素对方斑东风螺稚螺24 h 半致死质量浓度（LC50）分别为210.54 mg·L -1、32.52 mg·L -1和8.13 mg·L -1；48h LC50分别为93.52 mg·L -1、16.90 mg·L -1和3.96 mg·L -1；毒性大小依次为敌百虫﹥氯氰菊酯﹥阿维菌素，安全质量浓度（SC）分别为5.54 mg·L -1、1.37 mg ·L -1和0.28 mg·L -1。在上述安全质量浓度范围内，这些药物均可杀灭桡足类或其他寄生虫，但考虑药物残留和对水环境的污染，在生产中尽量采用生态防治办法，避免使用药物。

The acute toxicities of trichlorfon,cypermethrin and avermectins to juvenile snail of Babylonia areolata were studied with method of semistatic water. The results show that the 24 h LC50 's of trichlorfon,cypermethrin and avermectins were 210. 54 mg·L - 1 , 32. 52 mg·L - 1 and 8. 13 mg·L - 1 ,respectively,while 48 h LC50 's were 93. 52 mg·L - 1 ,16. 90 mg·L - 1 and 3. 96 mg·L - 1 ,respec-tively. The order of lethality was trichlorfon ﹥ cypermethrin ﹥ avermectins,and their safe concentrations(SC)to juvenile snails of B. areolata were 5. 54 mg·L - 1 ,1. 37 mg·L - 1 and 0. 28 mg·L - 1 ,respectively. It is concluded that they all can be used in breeding of B. areolata,but considering environmental impact and drug residues,they should not be abused in practical application.
