show Abstracthide AbstractInsect olfactory system is a highly specific and sensitive chemical detector, which plays important roles in feeding, mating and finding an appropriate oviposition site in adult. Bombyx mori was domesticated from B. mandarina, and its olfactory response to environmental odorants was clearly decreased. However, the molecular mechanism is poorly understood. In this study, we compared the antennal transcriptomes of the domestic and wild silkworms using RNA Sequencing (RNA-Seq).
