Stem-boring beetle attack can be devastating, both to the host plant, and to conservation-minded landowners. Here we provide the results of our research into the impact of the jewel beetle Cyrioides imperialis (Fabricius, 1801) on Banksia marginata specimens in a mixed tree planting, established on a property at Seymour, Tasmania, between 2007 and 2009. In finding 54% of the banskias were attacked by the beetle, tree location, position in the planting and rainfall were each likely to influence the degree of attack on the trees.

Covenanted land provides an important service to the conservation of native fauna and flora. Here we report on the impact of the jewel beetle Cyrioides imperialis (Fabricius, 1801) (Coleoptera: Buprestidae) on a 10-13-year-old Banksia marginata revegetation stand in eastern Tasmania.
