Abstract: [Objectives]  To elucidate the biological characteristics of Aiolomorphus rhopaloides Walker on Semiarundinaria fastuosa, Phyllostachys praecox, and Phyllostachys edulis. [Methods]  Three adult populations of A. rhopaloides were obtained by laboratory rearing of gall insects. Species identification was based on a combination of morphological and molecular methods. Gall size, adult weight, sex ratio, longevity, initial egg load, number of ovarioles and egg size, were determined by weighing, measuring with vernier calipers, microscopic examination and counting. [Results]  Cylindrical, single chamber galls were formed on S. fastuosa, Ph. praecox, and Ph. edulis. The size of galls on different host plants could be ranked in descending order as follows; S. fastuosa (118.09±28.32) mm3 > Ph. praecox (108.92±28.34) mm3 > Ph. edulis (67.38±15.44) mm3. Adults emerged earlier on S. fastuosa and Ph. praecox than on Ph. edulis. The adult female/male ratio on S. fastuosa, Ph. praecox, and Ph. edulis was 1.791, 1.941 and 0.821, respectively. Adult females on S. fastuosa were heavier (7.90±0.83) mg/adult, had the most initial egg load (119.4±13.69) eggs/adult and the largest egg size (length (545.36±30.74) μm, width (137.27±12.20) μm. The weight of adult females on Ph. praecox was significantly higher than that of those on Ph. edulis (P<0.05) but there was no significant difference in initial egg load and egg size between these host plants (P>0.05). [Conclusion]  A. rhopaloides is a pro-ovigenic chalcidoid and adult female size, initial egg load and egg size varies significantly among the host plants S. fastuosa, Ph. praecox, and Ph. edulis.
