Feeding range of Sitona regensteinensis Hbst. (Coleoptera: Curculionidae), a potential agent for biological control of Cytisus scoparius (L.) link (Broom) in New Zealand

Abstract

The weevil Sitona regensteinensis is being considered for biological control of Cytisus scoparius in New Zealand. Adult feeding tests demonstrated that while foliage of C scoparius was preferred, weevils fed also on Chamaecytisus palmensis and Lupinus arboreus. Tests with the root‐feeding larval stage have yet to be completed.
