Abstract

Contiguous 14,535 and 14,536 nt near complete mitochondrial genome sequences respectively were obtained for Ostrinia nubilalis and Ostrinia furnicalis. Mitochondrial gene order was identical to that observed from Bombyx. Sequences comparatively showed 186 substitutions (1.3% sequence divergence), 170 CDS substitutions (131 at 3(rd) codon positions), and an excess of transition mutation likely resulting by purifying selection (d(N)/d(S) = omega congruent with 0.15). Overall substitution rates were significantly higher at 4-fold (5.2%) compared to 2-fold degenerate codons (2.6%). These are the 3(rd) and 4(th) lepidopteran mitochondrial genome reference sequences in GenBank and useful for comparative mitochondrial studies.
