摘要

The genus Anastoechus plays a crucial role in ecosystems, functioning both as a pollinator and as a natural enemy, with its larvae parasitizing grasshopper egg masses and adults visiting flowers. Despite its ecological significance, research on Anastoechus remains limited. In this study, we present a chromosomal-level genome assembly of Anastoechus asiaticus, utilizing BGI sequencing, PacBio sequencing and High-throughput chromosome conformation capture (Hi-C) technology. This represents the first genomic data for the genus Anastoechus, with a final genome size of 512.14 Mb and a scaffold N50 of 82.71 Mb. Genome annotation identified 12,751 protein-coding genes, of which functional annotations are available for 11,305. Additionally, non-coding RNA annotation revealed 1,753 tRNAs, 56 miRNAs, 79 rRNAs, and 49 snRNAs. Repetitive elements account for 290.64 Mb, constituting 56.75% of the genome. This high-quality genome provides valuable data for future studies on population genetics, ecological adaptation, and the evolution of Bombyliidae and other related insect groups.
