Marrubium vulgare L. (Lamiaceae) was surveyed in western Mediterranean Europe and Morocco to identify the phytophagous insect fauna associated with this weed and to select species having some potential as biological control agents. Twenty-seven insect species were found to feed on the plant. Two Lepidopteran species have been introduced into Australia to control the weed. Five additional species (three Lepidoptera and two Coleoptera) are considered as potential candidates for introduction and host-specificity tests.
