Abstract
Abstract The giant water bug, Lethocerus indicus (Lepeletier and Serville, 1825), is one of the most important edible insects in Thailand. This study investigated the genetic diversity of L. indicus from natural resources in northeast Thailand by using mitochondrial DNA sequences. Ninety adults of L. indicus were collected from 12 different localities by light trap and hand-net methods. Nucleotide and haplotype diversity of cytochrome c oxidase subunit 1 (CO1) sequences were relatively high. The 43 CO1 haplotypes (Li1–Li43) with 26 unique haplotypes were classified and used to generate a star-like haplotype network. The most common haplotypes were Li6 and Li2 shared between 19 and 15 sequences, respectively from nine different localities. A phylogenetic tree clearly separated L. indicus from the other species and closely clustered with a sibling species, L. patruelis (Stål, 1854). However, the comprehensive genetic variation of L. indicus covering broad range of areas needs to be further explored.
泰国东北部自然生境巨型水虫(leeletier and Serville, 1825)的遗传变异(半翅目:水虫科)
摘要巨型水蝽,Lethocerus indicus(Lepeletier and Serville,1825),是泰国最重要的食用昆虫之一。本研究利用线粒体DNA序列对泰国东北部自然资源中印度乳杆菌的遗传多样性进行了研究。采用光阱法和手网法从12个不同地点采集了90只印度乳杆菌成虫。细胞色素c氧化酶亚基1(CO1)序列的核苷酸和单倍型多样性相对较高。对43个具有26个独特单倍型的CO1单倍型(Li1-Li43)进行了分类,并用于生成星形单倍型网络。最常见的单倍型是Li6和Li2,共有19和15个序列,分别来自9个不同的地方。系统发育树清楚地将印度乳杆菌与其他物种区分开来,并与一个兄弟物种patruelis紧密聚集在一起(StåL,1854)。然而,印度乳杆菌的综合遗传变异覆盖范围广泛,有待进一步探索。
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.
