Interpretive Summary: Cottony ash psyllid (CAP, Phyllopsis discerpans) is an introduced insect to North America where its presence is associated with decline and death of native and exotic ash trees. However, little is known about this insect. Therefore, research was conducted to acquire the mitochondrial genome from CAP collected in Saskatoon, Canada. This resource will improve knowledge about this discrete introduced population and could be utilized in comprehensive studies to understand population diversity worldwide.

Technical Abstract: Cottony ash psyllid (CAP, Phyllopsis discrepans) is an important, invasive insect pest of ash trees in North America where it has established populations. However, not much is known about the diversity of its introduced population. In this study, a CAP mitochondrial genome (mitogenome) sequence was obtained from a collection in Saskatoon, Saskatchewan, Canada. The CAP mitogenome is a circular DNA of 18,824 bp, encoding 13 protein-coding genes, 21 transfer RNA genes, and 2 ribosomal RNA genes. BLAST search using the CAP mitogenome as query against GenBank sequence database showed the mitogenome of Euphyllura phillyreae (15,202 bp) was the most similar (Query Coverage = 77%; Percentage Identity=78.90%). The CAP mitogenome is significantly different from other known psyllid mitogenomes with the presence of a 4,357 bp control region (CR). The mitogenome sequence will further genomic understand of CAP.
