Abstract: By correlating the codon usage in four insects (the honeybee, red flour beetle, mosquito and fruit fly) with six honeybee host specific viruses, we found that the codon usage patterns of the bee viruses were strongly related to that of the honeybee and only weakly related to the red flour beetle. The insects shared varying degrees of codon usage similarity which roughly follow the known phylogenetic relatedness. All of the codon usage similarity can be described by relatedness-by-descent except for the high codon usage similarity between the honeybee and honeybee associated viruses. This evidence for the convergent evolution of the honeybee viruses toward the codon usage of the honeybee suggests that small host specific viral genomes have the freedom to quickly optimize codon usage to successfully parasitize their preferred host. The codon usage co-evolution of the six host specific honeybee viruses towards the codon usage of the honeybee described in this paper is the first evidence for codon usage correlation between an insect host and a single stranded RNA virus. © 2008 Elsevier Inc.
