| Research Abstract |
Sex pheromone plays a critical role in species-specific mating behaviors, however, little is known about what changes occur in genes responsible for the behaviors. Thus, we performed a comparative analysis of genes associated with sex pheromone response and synthesis between Ostrinia furnacalis and Ostrinia latipennis. We constructed genomic fosmid libraries of the species, and generated PCR-based screening system for them. Then, we isolated clones that contain genes encoding receptors, binding proteins and desaturase of sex pheromone, and determined genomic sequences (330kb for O. furnaclis and 265kb for O. latipennis)
