5 CONCLUSION
In this study, we presented a high-quality chromosome-level genome assembly of M. dirhodum with the aid of PacBio long HiFi reads and Hi-C technology. The 447.8 M M. dirhodum genome encoded 18,003 protein-coding genes. This is the first assembled genome forM. dirhodum and will facilitate further research related to pesticide resistance, virus transmission and other aspects of M. dirhodum biology. Comparative transcriptomic analyses identified a number of DEGs that might be related to wing dimorphism, including ILR, Foxo, ECR, brc, and FTZ-F1. These results lay the foundation for future in-depth research on wing dimorphism in M. dirhodum .
