Illiberis (Primilliberis) rotundata Jordan, 1907 (Lepidoptera: Zygaenidae) is an orchard pest distributed in Honshu, Shikoku and Kyushu in Japan and also in China, Korea, Mongolia and Russia (south‐eastern Siberia and Far East). For optimizing a known sex attractant lure containing sex pheromone components of the species (2R)‐butyl (7Z)‐dodecenoate and (2R)‐butyl (9Z)‐tetradecenoate, field work was organized in three cherry tree plots in Naruto, Tokushima in 2009 and 2010. As a result, the mixture of (2R)‐butyl (7Z)‐dodecenoate and (2R)‐butyl (9Z)‐tetradecenoate in a ratio of 30:100–50:100 (130–150 µg, respectively) was found to be the most attractive for the males of this pest. The seasonal flight of I. rotundata in Naruto, Japan as estimated by pheromone traps started at the end of May and lasted up to the end of June with a mass flight at the very end of May to first week of June.
