Abstract
Chironomidae commonly inhabits most aquatic habitats and often dominate aquatic insect communities in abundance and species richness. Despite their ecological importance, the diversity and distribution of chironomids in the Lake Victoria ecosystem of Kenya have not been studied to date. Here we report on the diversity and distribution of adult Chironomidae in Usenge, Mbita and Ogal beaches of the Lake Victoria ecosystem in Kenya using morphological features and sequence data of Cytochrome c oxidase subunit I (COI) gene. Wing venation-based microscopic characterization identified four genera, Tanypus, Coelotanypus, Dicrotendipes and Chironomus. The COI gene barcoding further revealed several species, including Kiefferulus brevibucca, Chironomus flaviplumus, Polypedilum fuscovittatum, Polypedilum sp. and Dicrotendipes sp. The identified species were grouped into three clusters based on neighbor-joining phylogenetic approach. Differences in species richness were observed among the three study sites, with Mbita exhibiting the highest species richness. The evolutionary analysis revealed relatedness among all the identified species, suggesting a shared recent common ancestor. Unlike previous studies, this study represents thefirst report on detailed characterization of Chironomidae in the Lake Victoria ecosystem of Kenya. Moreover, this study serves as a first step towards a comprehensive understanding of the range of species of Chironomidae inhabiting this ecosystem.

期刊介绍:
Scientia Agricultura Sinica seeks to publish those papers that are influential and will significantly advance scientific understanding in agriculture fields worldwide. Scientia Agricultura Sinica publishes manuscripts in the categories focusing on the core subjects listed below. -Review describes new development and highlight future directions of a specialized or interdisciplinary significance in agricultural sciences. They should be focused on providing insights and summary/context on the published findings and introducing new concepts or viewpoints for solving the important unresolved questions by presenting the research background, approach, and outlook of the field. Most Reviews are solicited by the editors, but unsolicited submissions may also be considered. -Research Article presents important new research results through reproducible experimental design, using genetic, biochemical, cell and molecular biological methods, statistical analyses, and other scientific methods. -Research Notes is for a concise, but independent report representing a significant contribution to agricultural sciences. It is intended to publish these results that are exceptional interest and particularly topical and relevant, but the preliminary results. Core Subjects: -Crop Genetics & Breeding·GermplasmResources·Molecular Genetics -Tillage & Cultivation·Physiology & Biochemistry -Plant Protection -Soil & Fertilizer·Water-Saving Irrigation·Agro-Ecology & Environment -Horticulture -Storage·Fresh-Keeping·Processing -Animal Science·Veterinary Science -Agricultural Ecology -Research Notes
