项目摘要

(1) Comparative studies of the male mating behaviors were carried out between two subspecies of the cabbage butterflies, Japanese subspecies (Pieris rapae crucivora) and British subspecies (Pieris rapae rapae) to determine whether there occurs behavioral isolation between them. The results showed :(1)Each males of the two subspecies were significantly more frequently attracted to the females of their own subspecies when the two subspecies of the female specimen were presented 15 cm apart.(2)Two subspecies of males, however, were also attracted to the female specimen of the other subspecies when the female specimen were presented 2 m apart.(3)There occurred inter-subspecies mating when males and females of the two subspecies were allowed to coexist in the same field net cage of 4×4×1.8m.(4)The results suggest that the behavioral isolation between the two subspecies should be rather partial, although each males of the two subspecies preferred the females of their own subspecies to those … More of the other one when the two subspecies of the female specimen were presented close to each other, 15 cm.(2) Experiments were carried out to determine whether the female wing color change depending on the seasonal forms and male mating behaviors of the different seasonal forms were investigated to determine whether and how they adjust their mating behaviors to the different seasonal forms of the females. The results showed :(1)The wing colors of the Japanese subspecies of female appear more yellowish and weaker ultraviolet-colored in the short day-length forms.(2) It was found that long day-length forms of males preferred long day-length forms of female to the short day-length forms of females, while the short day-length males did not so. This suggests that male's mate recognition system may change in accordance with the female wing color change.(3) DNA analysis was carried out to determine the dendrogram of the cabbage butterflies from some districts of the world. The results showed :(1)European cabbage butterflies can be genetically discriminated from those of Asian ones and the latter can be likewise subdivided into Chinese and Korean-Japanese groups.(2)It was suggested that ultra violet color might have evolved in an Asian cabbage butterflies.

(1)对菜粉蝶日本亚种和英国亚种的雄性交配行为进行了比较研究，以确定它们之间是否存在行为隔离。结果表明：(1)当雌性标本的两个亚种相距15 cm时，两个亚种的雄性均被各自亚种的雌性吸引；(2)当雌性标本相距2m时，两个亚种的雄性也被另一个亚种的雌性标本吸引；(3)当两个亚种的雌雄在4×4×1.8m的网箱中共存时，两个亚种的雄性和雌性发生了亚种间的交配。(4)结果表明，两个亚种之间的行为隔离应该是比较局部的。尽管两个亚种的雄性都更喜欢自己亚种的雌性而不是那些…当雌性标本的两个亚种相互靠近时，雌性标本的颜色更多，为15 cm。(2)进行了雌性翅膀颜色是否随季节变化而变化的实验，并调查了不同季节形式的雄性交配行为，以确定它们是否以及如何调整交配行为以适应不同的雌性季节形式。结果表明：(1)短日照雌性亚种的翅色较淡黄色，紫外光强度较弱。(2)长日照雄性比短日照雌性更喜欢长日照雌性，而短日照雄性则不是这样。这表明雄性的配偶识别系统可能会随着雌性翅膀颜色的变化而改变。(3)对世界上一些地区的菜心蝴蝶进行了DNA分析，确定了树状图。结果表明：(1)欧洲白菜蝶和亚洲白菜蝶可以进行遗传区分，亚洲白菜蝶也可以分为中国人和韩国人-日本人两类。(2)亚洲白菜蝶可能进化了紫外光的颜色。较少
