Cane Weevil Borer, Rhabdoscelus obscurus (Coleoptera: Curculionidae), a pest of palms in Northern Queensland, Australia

Abstract

In recent years the cultivation of ornamental palms (Arecaceae) has increased markedly in northern Queensland. Consequently, several insects have become important pests, particularly Rhabdoscelus obscurus (Boisduval), the cane weevil borer. The larvae of this beetle feed on various species of palms, making the plants unsaleable. Death or lodging of the trees may also result. This paper documents its pest status, derived from information in the literature and from consultation with local growers.
