Description
Summary:The giant ladybug Megalocaria dilatata (Fabricius) is a potential biocontrol agent and a valuable model for coccinellid genomics and evolutionary biology. However, the lack of a reference genome for M. dilatata has impeded further explorations into its evolution and constrained its use in pest management. Here, we assembled and annotated a high-quality, chromosome-level genome of M. dilatata . The resulting assembly spans 772.3 Mb, with a scaffold N50 of 72.48 Mb and a GC content of 34.23%. The Hi-C data aided in anchoring the assembly onto 10 chromosomes ranging from 43.35 to 108.16 Mb. We identified 493.33 Mb of repeat sequences, accounting for 63.88% of the assembled genome. Our gene prediction identified 25,346 genes, with 81.89% annotated in public protein databases. The genome data will provide a valuable resource for studying the biology and evolution of Coccinellidae, aiding in pest control strategies and advancing research in the field.
