Abstract

Abstract Rearing research is being conducted to conserve many endangered aquatic Coleoptera species; however, studies on Gyrinidae species are scarce. Herein, we present an efficient rearing method for the endangered species Dineutus mellyi mellyi Régimbart, 1882 (Coleoptera: Gyrinidae), practiced at the Ishikawa Insect Museum. The survival rate of the larvae reared using this method at different developmental stages was as follows: first-instar larvae, 100% (n = 26); second-instar larvae, 100% (n = 26); third-instar larvae, 92% (n = 24); landing to pupate, 73% (n = 19); pupa, 73% (n = 19); and emergence to escape from pupal chamber, 69% (n = 18). Therefore, we recommend this method for sustainable ex situ conservation of this species. This method can be generalised to other Gyrinidae and aquatic Coleoptera species.

濒危物种Dineutus mellii mellii Régimbart的饲养方法，1882年（鞘翅目：Gyrinidae）

摘要正在进行饲养研究，以保护许多濒危水生鞘翅目物种；然而，关于Gyrinidae物种的研究却很少。在此，我们为濒危物种Dineutus mellii mellii Régimbart，1882（鞘翅目：Gyrinidae）提出了一种有效的饲养方法，该方法在石川昆虫博物馆实践。用该方法饲养的幼虫在不同发育阶段的存活率分别为：1龄幼虫100%（n = 26）；二龄幼虫，100%（n = 26）；三龄幼虫92%（n = 24）；降落成蛹，73%（n = 19）；蛹，73%（n = 19）；羽化后逃离蛹室的比例为69%（n = 18）。因此，我们建议采用这种方法对该物种进行可持续的迁地保护。这种方法可以推广到其他Gyrinidae和水生鞘翅目物种。

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.
