在室温条件下分三组培养发头裸腹氵蚤（ＭｏｉｎａｉｒｒａｓａＢｒｅｈｍ），以１．２５×１０６ｃｅｌｓ／ｍｌ酵母液为培养液。设Ａ组为对照组，Ｂ组每天更换１０ｍｌ培养液，Ｃ组始终不给予光照。结果是Ｂ组食物浓度过高，种群增长受较明显的抑制，表现为个体数少、寿命短、怀卵期延长。培养期间不给光照的Ｃ组，其种群增长也不及对照组 At room temperature, three groups were used to cultivate Moinairrasa Brehm, with 1.25 × 106cels / ml yeast extract as culture medium. A group as the control group, B group daily replacement of 10ml culture medium, C group is always given no light. As a result, the concentration of food in group B was too high, and the population growth was more obviously inhibited. The result was that the number of individuals was small, the life span was short, and the pregnancy period was prolonged. C group did not give light during culture, its population growth is less than the control group
