Outline of Final Research Achievements

It is most likely that phytophagous insects find their edible plant by means of olfaction, and odorant receptor genes is one of the most important candidates determining on which plant female moths lay eggs. we determined 511 Mb whole genome sequences of the Asian corn borer, Ostrinia furnacalis, and isolated fosmid clones to determine OR gene structures precisely. Consequently, we found nearly 60 OR genes, some of which were in tandem arrays. Additionally, we screened genomic libraries of O. nubilalis and O. latipennis, congeners of O. furnacalis, and isolated clones containing OR genes, and determined their sequences for comparison.
