Cleopus japonicus : releases and distribution of the buddleia biological control agent in New Zealand

Analyses the current distribution of the buddleia leaf weevil (Cleopus japonicus) and its recorded patterns of dispersal from known release sites in the four and a half years since its release by Scion as a biological control agent for buddleia (Buddleja davidii Franchet), which is an invasive weed in exotic and indigenous forests in NZ. Explains that it colonises disturbed sites, competes with tree crops and displaces native pioneer species.
