Abstract

Geographic variation in the sex pheromone of the Asian corn borer, Ostrinia furnacalis (Guenée), was surveyed in populations sampled at four locations ranging from 39.7°N to 32.9°N in Japan. The sex pheromone of the three northern populations was composed of (E)- and (Z)-12-tetradecenyl acetates with a mean E proportion of 36–39%. The southernmost population (Nishigoshi) had the same components but with a significantly higher E composition of 44%. The frequency distribution of the E ratio in the Nishigoshi population exhibited a small peak near 38% and a major peak near 46%. A family-wise analysis of the sex pheromone of this population confirmed that there were two distinct phenotypes regarding the E ratio. An “≍46% E strain” inhabits southern parts of Japan, in addition to an “≍38% E strain,” which seems to be predominant in other regions of Japan.
