| Anthraquinones in the Leaf Beetle Trirhabda geminata (Chrysomelidae)  | | | | Abstract
| Hydroxylated anthraquinones have been found to accumulate in different developm ental stages of the chrysomelid beetle Trirhabda geminata. Eggs, larvae and adults were analyzed by HPLC and GC-MS. Each developm ental stage analyzed contained l,8-dihydroxy-3-methyl-anthraquinone (chrysophanol) and 1,8-dihydroxyanthraquinone (chrysazin). No anthraquinones were detected in the faeces of T. geminata. The level of stored anthraqui nones did not change during starvation. In the host plant of this specialist herbivore, the brittlebush Encelia farinosa (A steraceae), anthraquinones were not detected. Possible biolog ical functions of anthraquinones stored in T. geminata are discussed. | | | |
