Abstract

The genome of the hemlock woolly adelgid (Adelges tsugae) is presented in 10 chromosomal pseudomolecules along with 132 unplaced scaffolds for a combined length of 216.56 Mb. The genome is highly contiguous with an N50 of 20.54 Mb and its longest scaffold 37.41 Mb in length. The assembly recovered 97.7% of benchmarked universal single-copy Hemiptera orthologs (BUSCO) with an overall completion score of 98.6%. On the basis of chromosomal synteny with other aphid genomes, the hemlock woolly adelgid’s genome is composed of eight autosomes and two sex (X) chromosomes. Annotation of the assembly identified 11,800 coding genes, 1,930 noncoding genes, and 20,403 mRNA transcripts. The mitogenome is also presented in a single, annotated, circular contig 25,980 bases in length.
