摘　　要：研究4种杀虫药物对盐生杜氏藻生长的致毒效应,结果表明:虫敌、纤源净、马拉硫磷、虫水安均不同程度上抑制盐生杜氏藻的生长繁殖,超过一定浓度后引起藻体的负增长,同时采用回归方程求出了4种药物对盐生杜氏藻24、48、72、96 h的半效应浓度EC50.The toxic effects of four insecticides（Beta-cypermethrin,Xianyuanjing,Malathion,Chongshuian）on growth of Dunaliella salina were studied.The results showed that the growth and reproduction of Dunaliella salina were inhibited by Beta-cypermethrin,Xianyuanjing,Malathion,Chongshuian in different degree,and negative growth was caused over a certain concentrations.Meanwhile,24 h,48 h,72 h,96 h half-effective concentrations EC50 of the four drugs on Dunaliella salina were calculated out using the regression equation.
