摘    要:研究中华真地鳖EupolyphagasinensisWalker的断足时间及数量对发育历期的影响,以及不同龄期断足处理后发育历期间的差异。以8龄若虫为研究对象,发现其再生临界期为20~26日龄。不同日龄的8龄若虫断去1条后足,蜕1次皮后能再生的若虫从断足至蜕皮的平均时间与8龄的正常历期相近,整个8龄若虫的发育历期均比正常历期长,并随断足处理日龄的增加而逐渐增加。蜕1次皮后断足没有再生的绝大部分个体,8龄若虫的历期均比正常历期短。以3日龄的4龄若虫为处理对象,发现断去不同数量的足后(蜕1次皮后均能再生),从断足至蜕皮的历期及4龄的历期,均随虫体断足数量的增加而增加,但断去1条或2条后足处理,从断足至蜕皮的历期间及断足处理后4龄历期与正常历期间的差异不显著。不同虫龄的若虫断去1条后足的腿节后1次蜕皮后能再生的大部分个体,从断足至蜕皮的时间比同龄若虫的正常历期稍长,所延长的时间相当于从龄初至断足处理的时间,而断足后1次蜕皮未再生的其余个体从断足到蜕皮的时间均很短。

关 键 词:中华真地鳖  断足再生  发育历期  再生临界期

Abstract:Influence of leg amputated phase and amount on development duration of Eupolyphaga sinensis Walker were studied. With 8th instar nymphs, the critical period for regeneration was from 20 to 26 days-old. The mean development time from operation to new-molting was close to the normal, but the instar duration took more time than normal to complete. The instar duration of the fourth instar individuals' amputated different amount legs increased with the degrees of amputation, though nymphs amputated a hind leg or a pair of hind legs developed with no significant difference.Instars did not influence the effect of amputation on duration of instar development. Average instar duration was longer than the normal duration, and the extended time was just as long as the time from the preoperative moulting to operation.
Keywords:Eupolyphaga sinensis  amputation  regenerated leg  regenerative critical period  duration
