| 摘 要： | 于2005年3-5月、9～11月对生活于鲁中山区的东亚三角头涡虫（Dugesia japonica）的有性生殖过程进行了研究，发现鲁中山区东亚三角头涡虫1年只有1次有性生殖过程。卵囊产出的高峰在4月，卵囊孵化与种群密度最高峰在5月，其有性生殖过程与温度、食物、虫体大小密切相关。经实验观察1个卵囊最多能孵出涡虫幼体10条，最少3条。

| Abstract: | The sexual reproduction process of Dugesia japonica in the middle mountain areas of Shandong Province was studied from March to May and September to November of 2005. We discovered that Dugesia japonica had only one sexual reproduction process a year. The highest oocysts producing period occurred in April, and the highest occyst hatching and density of population was in May. And the sexual reproduction process had relation to temperature, food and size of planarians. Every occyst could hatch 3 larvae at least and 10 at most. |
