The Hakea seed-moth, Carposina autologa Meyrick was released in South Africa for the biological control of Hakea sericea Schrader. The impact of the moth on the canopy-stored seeds of H. sericea was evaluated in the southwestern Cape over 3 years. The moth has reduced the mean accumulated seeds at the two study sites by 64.2% and 50.6%. It has shown a surprising ability to disperse and establish new colonies at low population levels. Although seed destruction is not severe, it is expected to contribute to the control of the weed.
