Abstract

The establishment and spread of the seed fly Mesoclanis polana Munro, an introduced biological control agent for Chrysanthemoides monilifera (L.) Norlindh, is described. From an initial release of 124 adult flies in August 1996, the species occupied virtually the entire range of bitou bush by October 1998, from Rainbow Beach in the north to Tathra in the south, a distance of over 1200 km. Early data on abundance are provided.
