This article deals with the release of buddleia leaf weevil cleopus by Ensis as a biological control agent for buddleia. According to monitoring efforts in New Zealand, cleopus seems to be establishing well in trial sites in North Island forests. Other sites chosen for the release of cleopus were Kinleith, Lake Taupo Forests, the Esk Forest in Hawkes Bay and Rawhiti Forest Farm near Ohope. To get the biological control agent established in the environment is the primary purpose of these releases. Initial findings showed that feeding damage to buddleia plants within the central release is considerable. Another objective of cleopus is to reduce costs associated with weed control and growth loss in young trees, as well as provide some control in natural areas where access is difficult.
