AbstractThe fungus Metarhizium anisopliae is a naturally occurring pathogen of soil insects in Australia. Metarhizium can be used as a bioinsecticide for control of canegrubs by mass-producing spores on rice and applying the resulting product into canefields. Numbers of greyback canegrub in plant cane have been consistently reduced by more than 50% when spores of isolate FI-1045 together with the rice medium have been applied at 33 kg/ha. About 18 t of this product were applied in semi-commercial trials in 1997-1999. The product was registered as BioCane™ Granules in March 2000. FI-1045 has also given some control of southern one-year canegrub. Another isolate, FI-147, significantly reduced numbers of negatoria canegrub the year after application into sugarcane ratoons, and increased cane yield. The same isolate was equally effective against French's canegrub in laboratory bioassays, and field trials are in progress against this pest. Trials have been less successful against Childers canegrub, and more effective isolates must be identified for this species. Trial results have been very poor against soldier fly; none of the isolates tested in bioassays was very virulent, and no further work is planned.
