为探究不同食物及食物密度对盐蚕豆虫（Fabrea salina）种群动力学的影响。本文采用商业酵母和杜氏藻（Dunaliella salina）两种不同类型的饲料喂食盐蚕豆虫，探究其种群动力学特征。结果表明，杜氏藻组的盐蚕豆虫具有较高的生长率[（0.78 ± 0.019）/d]、较低的世代时间[（0.89 ± 0.021）d]，内禀生长率为1.49/d，米氏常数值为1 121.32；商业酵母组生长率较低[（0.36 ± 0.001）/d]，世代时间较长[（1.93 ± 0.007）d]，内禀生长率为0.51/d，米氏常数值为2.68。One-way ANOVA检验结果表明，食物及食物密度对盐蚕豆虫的种群生长均有极显著影响（P < 0.01）。以密度为10 × 109 cells/L的杜氏藻投喂，可在短时间内实现盐蚕豆虫的高密度培养和利用，而酵母适用于实验室中盐蚕豆虫的保种工作。
The purpose of this paper is to investigate the effects of different food and food densities on the population dynamics of Fabrea salina. Commercial yeast and Dunaliella salina were provided to the F. salina. The F. salina fed by D. salina had the higher growth rate (0.78 ± 0.019 / d), and lower generation time (0.89 ± 0.021 d). Its intrinsic growth rate is 1.49/d, and the Michaelis constant was 1 121.32. However, the growth rate of F. salina fed by commercial yeast was lower (0.36 ± 0.001 / d), and the generation time was longer (1.93 ± 0.007 d); its intrinsic growth rate was 0.51/d and the Michaelis constant was 2.68. One-way ANOVA test results showed that the kind of food and food density had a significant effect on the population growth of F. salina (P < 0.01). Feeding F. salina by D. salina with a density of 10 × 109 cells/L can achieve high-density culture in a short period of time. While, yeast is suitable to feed F. salina to keep them in the laboratory for longer time.
