摘要
对中华虎凤蝶杭州种群与南京种群间主要生物学特征作了比较，结果表明，两种群除在各龄幼虫历期及取食量上有一定差异外，在卵孵化时间分布、幼虫存活率、幼虫总历期与总取食量、蛹历期及化蛹时间分布、羽化进度等生物学特征上并无明显差异。可见，中华虎凤蝶各种群间主要生物学特征极为相似。作者建议当某地种群濒危成数量急剧减少时，可通过引进异地种群加以补充。
Main biological characteristics of Luehdorfia chinensis Leech between Hangzhou and Nanjing population were compared. The results showed there were no significant differences in the distribution of egg hatching time , larval survival rate , larval total stadium , larval total feeding amount , pupal stadia , the distribution of pupating time and emergence progress between Hangzhou and Nanjing population. The dif- ferences in larval stadia and feeding amount of some instars were marked between these two populations. Based on these results , it could.be inferred that main biological characteristics among different populations of this butterfly were markedly similar. It is suggested that if the populations of this butterfly are endan- gered or sharply decreased in some regions , they can be supplemented by importing from other populations with more quanties in other regions.
