| 摘 要： | 报道了中华真地鳖Eupolyphaga sinensis Walker的断足再生特征。研究结果表明，不同虫龄期的若虫都有断足再生能力；足的不同部位断足后均能再生；断掉不同数量的足后，只要能成活均可再生。断足再生后，继续断掉再生足的原位或其他部位也可以再生。再生足的跗节均比正常的少一节，具有再生不完整性。断足后，只要经1～2次蜕皮，均可再生。断掉一对足的腿节后，再生足出现大小不一的现象，小的一般发育不全，断足数量多容易出现再生足发育不全。再生足比正常足要小，但生长速度要快，断掉足的腿节或跗节后的再生足经过2次蜕皮后基本可恢复到正常足大小。

| Abstract: | Leg regeneration was found in Eupolyphaga sinensis Walker. The characteristics of the regeneration were examined. The results showed that nymphs at all the instars had regeneration ability and legs amputated at any site could regenerate. Regenerated legs could be amputated and regenerate again. Tarsus of the regenerated leg was one segment less than the normal tarsus, which had five segments. If two femurs matched were amputated, the regenerated legs usually developed uncompleted, and one regenerated leg was larger than the other. Generally, the regenerated legs were in smaller size and lighter color. But the growth rate of the regenerated legs was faster. Legs amputated from femur and tarsus, if regeneration occurred, could grow back to the normal size after two rounds of ecdysis. |
