Research Abstract |
Female of swallowtail butterflies select their host plant by tasting using chemo-sensory hair on their tarsi. I identified a mechanism of taste receptor for oviposition behavior. When expression of the receptor gene is interfered by RNAi method, butterflies show reduced sensitivity for the synephrine, one kind of 10 oviposition stimulants. This result suggests that this receptor gene affect to evolution driven by host-shift of phytophagous swallowtail butterflies.
