Abstract

The impact of the hakea seed-moth Carposina autologa (Carposinidae) on the canopy-stored seeds of the weed Hakea sericea (Proteaceae).

Abstract

The effects of Carposina autologa (which was released in South Africa to control Hakea sericea in 1970) on canopy-stored seeds of the weed were evaluated in the southwestern Cape in 1988-91. Total seed destruction by C. autologa at the 2 study sites was estimated at 64.2 and 50.6%. H. sericea fruits with emergence holes were found 8 km south, 2 km north and 4 km northeast of release sites, indicating very good dispersal of the carposinid, probably wind-related.
