Biology and management of the redheaded pasture cockchafer Adoryphorus couloni (Burmeister) (Scarabaeidae: Dynastinae) in Australia: a review of current knowledge



The redheaded pasture cockchafer, Adoryphorus couloni (Burmeister) (Scarabaeidae: Dynastinae: Pentodontini) is a pest of semi-improved and improved pastures in south-eastern Australia. It is a native species that has adapted to managed pastures, and despite many years of research in attempts to control it, this species still causes major economic damage, especially to perennial dairy pastures in south-eastern Australia. This is a review of available information on A. couloni and identifies some basic information gaps that require addressing: correct identification of the main pasture beetles, more accurate detection and monitoring methods, and better information on its biology and ecology, especially its feeding behaviour in soil.
