The ladybird beetle Harmonia axyridis is an aphidophagous natural enemy in Japan. The alien plant Solidago canadensis is widespread in Japanese agricultural landscapes, and the alien aphid Uroleucon nigrotuberculatum parasitizes the plant. We examined the quality of the aphid as food for all developmental stages of H. axyridis . First‐instar larvae fed the aphid died within 2 days. Larvae at later developmental stages survived for significantly longer periods but died before pupation. Adults fed the aphid also died within 10 days. These results suggest that U. nigrotuberculatum parasitizing S. canadensis is unsuitable for H. axyridis during the beetle's entire life cycle.
