摘要： The fruit fly Zeugodacus tau (Diptera: Tephritidae) is a major pest of melons and other cucurbits in Southeast Asia. In this study, we used Illumina, Nanopore, and Hi-C sequencing technologies to assemble a reference genome of Z. tau at the chromosomal level. The assembled genome was 421.79 Mb and consisted of six chromosomes (one X-chromosome + five autosomes). The contig N50 was 4.23 Mb. We identified 20,922 protein-coding genes, of which 17,251 (82.45%) were functionally annotated. Additionally, we found 247 rRNAs, 435 tRNAs, 67 small nuclear RNAs, and 829 small RNAs in the genome. Repetitive elements accounted for 55.30 Mb (13.15%) of the genome. This high-quality genome assembly is valuable for evolutionary and genetic studies of Z. tau and its relative species.
