| Research Abstract |
We generated transgenic silkmoths expressing an odorant receptor for general odorants (Or82a) from the fruit fly under the control of the sex pheromone receptor gene promoter in the silkmoth. Male moths expressing Or82a display pheromone searching behavior in response to geranyl acetate, one of ligands of Or82a, in dose-dependent manner. Expression of Or82a does not affect projection pattern of bombykol receptor neurons. These results indicate that odor selectivity for initiation of pheromone searching behavior can be genetically modified by ectopic expression of general odorant receptors in bombykol receptor neurons, and open the way to utilize male silkmoths as biosensors for various odorants.
