Figure 1. Trans-membrane segments in the domain II voltage-gated sodium channel with reference to codon position of the most frequent non-synonymous mutations and nucleotide variation in the codling moth sequences.

Polymorphic sites in the nucleotide sequences are indicated as numbers (13 substitutions) or letter (4 indels) using Syria1 sequence (1859 bp) as reference (Genbank accession number GU082334, Table 5). Arrows indicate the positions of the primers used for PCR-RFLP and sequencing analyses (Table 3).
