Description	Sexually dimorphic galls are rare among gall-inducing insects and the reason for their occurrence is unknown. The pteromalid wasp Trichilogaster acaciaelongifoliae, which induces galls on Acacia longifolia, is one such species. The anatomical and physiological attributes of male and female galls are examined and compared. Histological preparations are used to characterize anatomical differences between male and female gall chambers. Concentrations of auxin and cytokinin in normal buds, galled tissues, and larvae of both sexes are measured. Tissues from female chambers induce stronger cytokinin-like bioactivity than tissues from male chambers. Female larvae have considerably higher concentrations of cytokinins than male larvae; higher auxin-like bioactivity than in normal or galled plant tissues; and almost twice concentration of auxin than male larvae. These findings suggest that differing levels of phytohormones are involved in development of sexual dimorphism of gall structures.
