Abstract
To assess vespicochory in Aristolochia (Aristolochiaceae), we conducted preliminary observations of Aristolochia shimadae under cultivation and in its natural habitat. Two paper wasp species (Polistes spp.) were observed visiting freshly dehisced capsules of cultivated plants of A. shimadae. After removing the seed from the capsule and licking the juicy and sticky substance surrounding it, paper wasps bit off and carried away only a part of the raphe. This behavior suggests that the capsule, including the substance surrounding the seeds, is attractive to them, and the raphe is equivalent to an elaiosome. In our field observations of A. shimadae in a natural habitat, a wasp (Vespula shidai) carried away a seed after licking the juicy and sticky substance surrounding it. This observation of vespicochory is the first report on A. shimadae and the first on angiosperms in Japan.
为了评估马兜铃科（Aristolochiaceae）马兜铃属（Aristolochia）马兜铃属植物的吸浆传毒能力，我们对栽培中的马兜铃（Aristolochia shimadae）及其自然栖息地进行了初步观察。我们观察到两种纸蜂（Polistes spp.）从蒴果中取出种子并舔食其周围多汁的粘性物质后，纸蜂只咬下并带走了部分种皮。这种行为表明，蒴果（包括种子周围的物质）对它们有吸引力，而剑突就相当于elaiosome。我们在自然栖息地对 A. shimadae 进行实地观察时，一只黄蜂（Vespula shidai）在舔食了种子周围多汁的粘性物质后带走了一粒种子。这次观察到的巢茧寄生现象是关于 A. shimadae 的首次报道，也是日本被子植物的首次报道。
期刊介绍：
Plant Species Biology is published four times a year by The Society for the Study of Species Biology. Plant Species Biology publishes research manuscripts in the fields of population biology, pollination biology, evolutionary ecology, biosystematics, co-evolution, and any other related fields in biology. In addition to full length papers, the journal also includes short research papers as notes and comments. Invited articles may be accepted or occasion at the request of the Editorial Board. Manuscripts should contain new results of empirical and/or theoretical investigations concerning facts, processes, mechanisms or concepts of evolutionary as well as biological phenomena. Papers that are purely descriptive are not suitable for this journal. Notes & comments of the following contents will not be accepted for publication: Development of DNA markers. The journal is introducing ''Life history monographs of Japanese plant species''. The journal is dedicated to minimizing the time between submission, review and publication and to providing a high quality forum for original research in Plant Species Biology.
