Mutant Harmonia axyridis raw sequencing data of CRISPR/Cas9 induced mutations in the genes laccase2 and scarlet

Harmonia axyridis (Pallas), commonly known as the Asian lady beetle, is a native insect species of Asia that has been intentionally introduced to various regions for biocontrol purposes. However, its widespread presence beyond its original release sites suggests a high degree of invasiveness. In this study, we utilized the CRISPR-Cas9 approach to achieve precise genome editing in H. axyridis. Specifically, we targeted two genes in H. axyridis, laccase2 and scarlet, knockdown of which orthologs in other insects showed visible phenotypic changes. The knockout laccase2 resulted in an early-detectable phenotype but also in lethality. However, we successfully established a viable and genetically stable mutant colony by disrupting the scarlet gene, resulting in beetles with white eyes. Our findings contribute to the expanding knowledge of genetic manipulation in H. axyridis and provide insights into its potential for future research and practical applications for biocontrol and invasive species management.
