摘要我们研究了日本冲绳黄鱼Hypoponera bondroiti的生殖行为。本种有二形无翅麦角雄虫(主要和次要)，二形生殖雌性(有翅女王和无翅生殖间种)，以及工蚁。工人们既没有卵巢，也没有受精膜。主要的麦角类雄性是最大的群体成员。两只主要雄性在巢中相互打斗，直到其中一只消失，另一只占据了蜂巢的房间，在那里蜂王出现并交配。小麦角类雄鸟也会互相打架，尽管它们似乎不那么好斗，导致偶尔会有多只未成年雄鸟在同一个巢室里同居。大的雄性从不攻击小的，允许它们共存在同一个巢穴中。未成年的雄性似乎会模仿雌性。大雄鸟和小雄鸟都与有翅的蜂王和巢内的种间交配。交配后，一些有翅蚁后掉落翅膀留在巢中，而另一些则离开巢在实验室分散。种姓间的人留在鸟巢里。
SummaryWe studied the reproductive behavior of the ponerine antHypoponera bondroiti from Okinawa, Japan. This species has dimorphic wingless ergatoid males (major and minor), dimorphic reproductive females (alate queens and wingless reproductive intercastes), and workers. Workers have neither ovarioles nor spermatheca. Major ergatoid males are the largest colony members. Two major males fought one another in the nest until one disappeared, leaving the other to occupy the nest chambers where queens emerge and mate. Minor ergatoid males also fought one another, although they seemed to be less pugnacious, resulting in occasional cohabitation of multiple minor males in the same nest chamber. Major males never attacked minor ones, allowing them to coexist in the same nest chamber. Minor males seemed to mimic females. Both major and minor males mated with both alate queens and intercastes within the nest. After mating, some alate queens shed their wings and remained in the nest, while the others left the nest for dispersal in the laboratory. Intercastes remained in the nest.
