abstract
the spotted alfalfa aphid (saa, therioaphis trifolii ) (hemiptera: aphididae) is a destructive pest of cultivated alfalfa ( medicago sativa l.) that leads to large financial losses in the livestock industry around the world. here, we present a chromosome-scale genome assembly of t. trifolii , the first genome assembly for the aphid subfamily calaphidinae. using pacbio long-read sequencing, illumina sequencing, and hi-c scaffolding techniques, a 541.26 mb genome was generated, with 90.01% of the assembly anchored into eight scaffolds, and the contig and scaffold n50 are 2.54 mb and 44.77 mb, respectively. busco assessment showed a completeness score of 96.6%. a total of 13,684 protein-coding genes were predicted. the high-quality genome assembly of t. trifolii not only provides a genomic resource for the more complete analysis of aphid evolution, but also provides insights into the ecological adaptation and insecticide resistance of t. trifolii .
