摘要为了保护和提供实验室用的珍稀昆虫，人工繁殖系统是至关重要的。然而，在食肉淡水昆虫如潜水甲虫的情况下，由于它们的高食物消耗率，水族馆中的恒定条件难以维持。此外，抽水系统造成的水循环表面波纹阻碍了小幼虫的呼吸。我们开发了一种新的开放式水族箱系统，成功地应用于饲养潜水甲虫，Dytiscus sharpi（Wehncke）（鞘翅目：Dytiscus sharpi亚科）的幼虫。与传统方法相比，高比例的幼虫发育成成虫。饲养的成虫与野外采集的成虫体型基本一致。该方法也可应用于其他珍稀物种的保护和繁殖，如水甲虫和水蝽。
Abstract For conservation purposes and to supply rare insects for laboratory use, a system for artificial breeding is crucial. However, in the case of carnivorous freshwater insects such as diving beetles, constant conditions in aquariums are difficult to maintain due to their high rate of food consumption. Furthermore, surface rippling caused by the pumping system for water circulation hinders the respiration of small larvae. We developed a new open aquarium system without water circulation that was successfully applied to the rearing of larvae of diving beetles, Dytiscus sharpi (Wehncke) (Coleoptera: Dytiscidae). In comparison to conventional methods, a high proportion of larvae developed into adult insects. The size of reared adults was almost the same as those of field-collected adults. The new method could be applied to the conservation and breeding of other rare species, such as water beetles and water bugs.
