ミヤマモンキチョウ浅間連山亜種（Colias palaeno aias Fruhstorfer）に及ぼすモンキチョウ（Colias erate poliographus Motschulsky）の交尾干渉

抄録

Following up on many eyewitness reports of Eastern Pale Clouded Yellow (Colias erate) in the Alpine Clouded Yellow (C. palaeno) habitat in the Asama mountain range as well as several reports of C. erate ♂ mating with C. palaeno ♀, distribution surveys and feeding and mating studies were conducted to clarify the presence and effect of C. erate in the C. palaeno habitat. The results confirmed mating interference of adult C. erate ♂ with C. palaeno in C. palaeno habitats of Mt. Yunomaru and Mt. Eboshi but that geneticintrogression was unlikely. Measures for the conservation of C. palaeno were discussed.
