试验观察了甲醛、次氯酸钠、次氯酸钙、碘和孔雀石绿对蒙古裸腹 (Moinamonggollica)生长、生殖和内禀增长率的影响。得出 5种药物对蒙古裸腹的毒性阈限分别为 2 5 1、 0 0 76、 0 0 85、 0 0 2 5、 0 0 4 0mg/L。这一结果表明 ,甲醛对蒙古裸腹 的毒性阈限远高于对褶皱臂尾轮虫 (Brachionusplicatilis)的 2 4hLC50 ,因而 ,可以作为在培养液中抑制轮虫的有效药物 The effects of formaldehyde, sodium hypochlorite, calcium hypochlorite, iodine and malachite green on the growth, reproduction and intrinsic rate of increase of Moinamonggollica were observed. The results showed that the toxicity thresholds of five kinds of drugs on M. mongolica were respectively 2 5 1, 0 0 76, 0 0 85, 0 0 2 5 and 0 0 40 0 ​​mg / L. This result shows that the toxicity threshold of formaldehyde to M. mongolica is much higher than that of H.chindii (24 hLC50), and therefore, it can be used as an effective drug to inhibit rotifer in C.fruitsi
