甲胺磷和乙酰甲胺磷对萼花臂尾轮虫实验种群动态的影响
EFFECTS OF METHAMIDOPHOS AND ACEPHATE ON EXPERIMENTAL POPULATION DYNAMICS OF ROTIFER BRACHIONUS CALYCIFLORUS
摘要
Abstract
Effects of sublethal levels (0.01,0. 1,1.0,10.0,100.0,1000.0 and 10000.0 (μg/L) of organophosphorus insecticides including tnethamidophos (O,S-Dimethyl phosphoramidothioate,CAS No. 10265-92-6) and acephate ( O, S-Dimethyl acetylphosphoramidothioate, CAS No. 30560-19-1) on population dynamics of rotifer Brachionus calyciflorus were studied by 3-day population growth test at 25+1℃ , in dark,and with 3. 0 × 106 cells/mL of S. Obliquus as the rotifers' food. The results showed that both methamidophos and acephate influenced significantly the population growth rate,the ratio mictic females/amictic females and the mictic rate of the rotifers. Methamidophos influenced markedly the carrying-egg females/noncarrying-egg females of the rotifers,but acephate did not. Compared to the controls, 100. 0 (μg/L methamidophos and 1. 0-10000.0 )μg/L acephate increased significantly the population growth rate, but the reverse was true for 1,000.0 and 10,000. 0 μg/L methamidophos. 1,000. 0 μg/L methamidophos increased significantly the ratio carrying-egg females/noncarrying-egg females. 0. 1 μg/L methamidophos and 10. 0-0000. 0 μg/L acephate increased significantly the ratio mictic females/amictic females, and both 0. 1 (μg/L methamidophos and 10 (μg/L acephate increased significantly the mictic rate. 10. 0-10000. 0 μg/L acephate significantly increased the resting egg production. The above-stated results indicatedthat sublethal levels of methamidophos and acephate influenced significantly the population dynamics of B. Calyciflorus.关键词
