| 摘 要： | 为了达到蚁狮的合理人工饲养，进行了不同饲食频率，不同饲养密度，不同沙粒粗细度三种条件各自对蚁狮种群密度分布的影响实验，结论是： １不同的饲食频率不影响蚁狮的种群密度分布，在经过几天调整后，其分布趋于稳定。其平均拥挤度２龄大于３龄。２加大幼虫密度对分布的影响表明，每头３龄幼虫适宜的占据面积为４０ｃｍ＾２左右，２龄为３０ｃｍ＾２左右。

| Abstract: | Experiments were conducted to study the distribution density of ant-lion larvae under different conditions. The results were as follows:1. The distribution density of ant-lion larvae was not influenced by the feeding interval of days: After a few days later, the distribution trended to be stable.2. The distribution frequency in each sample area showed that, the preferential space for one third-instar larva of ant-lion was about 40 cm2, and 30 cm2 for one second-instar larva.3. There was an evident influence of the diameter of sands on ant-lion life. The diameter of sands in 40 mesh was the most beneficial for its life. |
