Abstract

The redheaded cockchafer, Adoryphorus couloni, is a serious pasture pest of
south-eastern Australia. No chemical insecticides are registered for use against
A. couloni. Investigations into the biological control of this pest using the fungus
Metarhizium anisopliae, covered three main areas. The first of these were
laboratory studies on the affect of both spore concentration and temperature on
the virulence of the fungus. Secondly, field experiments were established to
determine the short-term and long-term biocontrol. Finally, an environmental
study examined the influence of abiotic factors on the distribution and
abundance of the natural M. anisopliae flora in pasture soils.
