Abstract

ABSTRACT Parasitoid wasps of the subfamily Hyptiogastrinae (Gasteruptiidae) are known to lay eggs in the nests of solitary bees and wasps. Their larvae are considered predator-inquilines, consuming the host’s eggs and larvae and then the nest provisions. Pseudofoenus extraneus is endemic to Fiji, and the only member of the subfamily Hyptiogastrinae known to have colonised the archipelago. The host relationships and oviposition sequence of this species have not been previously reported. We show that the primary host is the halictine bee Homalictus fijiensis and describe P. extraneus behaviour around Homalictus nest aggregations and the entering of host nests. Wasps were observed entering Homalictus nests on nine occasions, as well as perching near nests and antennating nest entrances. The high abundance of H. fijiensis in Fiji may help to explain how a parasitoid was able to successfully invade such a remote oceanic archipelago as Fiji.

斐济掠食性外腹小蜂的生殖行为学(膜翅目:腹小蜂科:腹小蜂科)

摘要拟寄生蜂属拟寄生蜂亚科(拟寄生蜂科)在独居蜂和胡蜂的巢中产卵。它们的幼虫被认为是掠食性昆虫，吃掉宿主的卵和幼虫，然后再吃巢穴的食物。外假腹蛇是斐济特有的，是已知的唯一在群岛上定居的假腹蛇亚科成员。寄主关系及产卵顺序未见文献报道。结果表明，其主要寄主为斐济家蜂(Homalictus fijiensis)，并描述了外扁蜂在斐济家蜂巢聚集和进入寄主巢周围的行为。有9次观察到小黄蜂进入家蝇巢，在巢附近栖息，并在巢口触须。斐济人在斐济的高丰度可能有助于解释一种拟寄生虫是如何成功入侵斐济这样一个遥远的海洋群岛的。

期刊介绍： Published since 1880, the Transactions of the Royal Society of South Australia is a multidisciplinary journal that aims to publish high quality, peer-reviewed papers of particular relevance to Australasia. There is a particular focus on natural history topics such as: botany, zoology, geology, geomorphology, palaeontology, meteorology, geophysics, biophysics, soil science and environmental science, and environmental health. However, the journal is not restricted to these fields, with papers concerning epidemiology, ethnology, anthropology, linguistics, and the history of science and exploration also welcomed. Submissions are welcome from all authors, and membership of the Royal Society of South Australia is not required. The following types of manuscripts are welcome: Reviews, Original Research Papers, History of Science and Exploration, Brief Communications, Obituaries.
