Pollination is the crucial stage for reproduction and survival of plants, therefore knowledge about the bionomics of pollinators is often critical for plant conservation. Bowenia spectabilis (Cycadales: Stangeriaceae) is a CITES‐protected cycad species endemic to the Wet Tropics Bioregion of Queensland, Australia. It is pollinated by a host‐specific weevil species, Miltotranes prosternalis (Lea, 1929) (Curculionidae: Molytinae), which breeds in its male cones but also visits its female cones and pollinates them. The association between the cycad and the weevil is an obligate brood‐site reward pollination system, in which the weevil is provided with food and a brood site by the plant in “return” for the service of pollinating it. To facilitate the knowledge of the natural history of this unique Bowenia pollinator, we developed a method for rearing mature larvae of M. prosternalis collected from the field in the laboratory. Furthermore, we summarize biological information of M. prosternalis gathered from previous studies and by firsthand observations in the wild and during rearing in captivity.

Miltotranes prosternalis (Lea, 1929) (Coleoptera: Curculionidae) 的生物组学和饲养，澳大利亚的一种互惠型苏铁传粉者

授粉是植物繁殖和生存的关键阶段，因此有关授粉媒介生物组学的知识通常对植物保护至关重要。Bowenia spectabilis (Cycadales: Stangeriaceae) 是澳大利亚昆士兰湿热带生物区特有的受 CITES 保护的苏铁物种。它由宿主特定的象鼻虫物种 Miltotranes prosternalis (Lea, 1929) (Curculionidae: Molytinae) 授粉，它在雄性球果中繁殖，但也会访问雌性球果并为它们授粉。苏铁和象鼻虫之间的联系是一种专性的繁殖地奖励授粉系统，其中植物为象鼻虫提供食物和繁殖地，以“回报”为它授粉。为了促进了解这种独特的波文尼亚传粉者的自然历史，我们开发了一种饲养从实验室田间收集的成熟的 M. prosternalis 幼虫的方法。此外，我们总结了从以前的研究和野外和人工饲养期间的第一手观察中收集的 M. prosternalis 的生物学信息。
