Abstract

Abstract Water beetles are holometabolous, which have a pupal period in their ontogeny. When rearing water beetles in a laboratory, both aquatic and land environments should be provided. We designed and created a new system for rearing water beetles, and tested it with five species. Seven parts of three-dimensional printed objects were assembled to make two containers for a larva and a pupa. The assembled container was half submerged in an aquarium filled with water. When the larva had grown enough for pupation, it spontaneously crossed a bridge to reach land and made a pupal chamber in the soil. The newly emerged adult then left the soil and went back to the container with water. The growth process from larva to adult can be achieved sequentially without human assistance. Most larvae could succeed in landing on the soil and returning to water using this system.

使用三维打印机制作的装置，从幼虫到成年水甲虫(鞘翅目)的顺序饲养方法

水甲虫是全变性动物，在个体发育过程中有蛹期。在实验室中饲养水甲虫时，应同时提供水生和陆地环境。我们设计并创造了一种饲养水甲虫的新系统，并对五种水甲虫进行了测试。三维打印物体的七个部分被组装成两个容器，分别装着一只幼虫和一只蛹。将组装好的容器一半浸泡在装满水的水族箱中。当幼虫长到可以化蛹的时候，它会自发地越过一座桥到达陆地，在土壤里造一个蛹室。然后新出的成虫离开土壤，带着水回到容器里。从幼虫到成虫的生长过程可以在没有人类帮助的情况下依次完成。利用这一系统，大多数幼虫可以成功地降落在土壤上并返回水中。

期刊介绍： Aquatic Insects is an international journal publishing original research on the systematics, biology, and ecology of aquatic and semi-aquatic insects. The subject of the research is aquatic and semi-aquatic insects, comprising taxa of four primary orders, the Ephemeroptera, Odonata, Plecoptera, and Trichoptera but also aquatic and semi-aquatic families of Hemiptera, Coleoptera, and Diptera, as well as specific representatives of Hymenoptera , Lepidoptera, Mecoptera, Megaloptera , and Neuroptera that occur in lotic and lentic habitats during part of their life cycle. Studies on other aquatic Hexapoda (i.e., Collembola) will be only accepted if space permits. Papers on other aquatic Arthropoda (e.g., Crustacea) will not be considered, except for those closely related to aquatic and semi-aquatic insects (e.g., water mites as insect parasites). The topic of the research may include a wide range of biological fields. Taxonomic revisions and descriptions of individual species will be accepted especially if additional information is included on habitat preferences, species co-existing, behavior, phenology, collecting methods, etc., that are of general interest to an international readership. Descriptions based on single specimens are discouraged. Detailed studies on morphology, physiology, behavior, and phenology of aquatic insects in all stadia of their life cycle are welcome as well as the papers with molecular and phylogenetic analyses, especially if they discuss evolutionary processes of the biological, ecological, and faunistic formation of the group.
