Abstract
Monochamus alternatus alternatus is the major vector of pinewood nematode, Bursaphelenchus xylophilus, in Asia. The length of the complete mitochondria genome of M. alternatus alternatus was 15,880 bp with 21% GC content, including 39.7% A, 12.3% C, 8.7% G and 39.3% T. There were 13 protein-coding genes, 22 tRNAs, 2 rRNAs, and one AT-rich region. This study provides a useful genetic information for subsequent study of the differences between M. alternatus subspecies.
