艳妇斑粉蝶生物学特性研究

Study on the biology of Delias belladonna(Fabricius)

艳妇斑粉蝶Delias belladonna(Fabricius)具有较高的经济、美学和生态价值,可用于观赏、工艺制作、活体放飞等。在云南省大理州洱源县,艳妇斑粉蝶一年发生1代,卵期8至12天,在6月至7月能发现卵;幼虫期约10个月,当年6月份至次年5月份能发现幼虫,其中1龄幼虫历期7至10天,2龄10至17天,3龄14至19天,4龄约5至6个月,5龄虫30至45天;蛹期20至35天,蛹主要出现在4月份至6月份;成虫发生在5月下旬至7月上旬。艳妇斑粉蝶以4龄幼虫越冬,其寄主植物为桑寄生Taxillus sutchuenensis和短梗钝果寄生Loranthus vestitus。艳妇斑粉蝶野外资源可进行有规划地可持续开发利用。

Delias belladonna has high economic, aesthetic and ecological value, and can be used for ornamental, craft production, living fly etc. In Eryuan County of Yunnan Province; this butterfly developed 1 generation each year under natural conditions, with the egg stage lasting about 8 to 12 days, occurring in June and July. Larva stage lasted about 10 months, occurring from the June of the first year to the May of next year, the first instar 1 arva 7 to 10 days, the second 10 to 17 days, the third instar 14 to 19 days, the fourth 5 to 6 months, and the fifth 30 to 35 days. The pupa stage was about 20 to 35 days, occurring from April to June; the adult lasted about half a month. The adult massively occurs in late May to early July. It goes through the winter with the fourth larva. Its host plants are Taxillus sutchuenensis and Loranthus vestitus. The wild resources of Delias belladonna can be planned to sustainable development and utilization.
