AREGULLIN, Manuel  and  RODRIGUEZ, Eloy. Sesquiterpene Lactone Sequestration by the Tortoise Beetle Physonota arizonae (Cassidinae). Rev. Soc. Quím. Méx [online]. 2003, vol.47, n.2, pp.143-145. ISSN 0583-7693.

The phenomenon of sequestration of plant secondary metabolites by herbivorous arthropods and its importance as an arthropod defense strategy is well documented in chemical ecology studies. Damsin (1), and the related terpene damsinic acid (2), are sesquiterpene lactones sequestered by the tortoise beetle Physonota arizonae (Cassidinae) from its host plant Ambrosia ambrosioides (Asteraceae) for possible chemical protection.

Keywords : Sequestration; sesquiterpene lactones; Asteraceae; Ambrosia ambrosioides; Cassidinae; Physonota arizonae; Coleoptera; tortoise beetles.
