Agriculture Victoria research scientists are investigating the use of biopesticides such as
entomopathogenic or insect-killing fungi to reduce populations of carpophilus beetles in
almondorchards.

Agriculture Victoria Research PhD student Will Boston said it is difficult to target
carpophilusbeetleswithconventionalpesticides.
“Spraying orchards may not be that effective as this beetle species resides within nuts,
additionally the beetles quickly spread to new season nuts by harbouring in residual nuts

This research involved testing the effectiveness of seven strains of the fungus Beauveria
bassiana against both adult and larval stages of two species of carpophilus beetles in
laboratoryconditions.
For the beetle species that favours almonds the mortality was 19 per cent when treated
with the most effective fungus, compared with 52 per cent for the beetle species that
favoursstonefruits.
However, when used against larvae, the mortality for both beetle species was generally
higher,withfourfungalstrainscausinggreaterthan80percentmortalityinthestonefruit
beetles, while only one fungus was effective against the almond beetles with 73 per cent
mortality.
“We found particular entomopathogenic strains can kill carpophilus beetles ? particularly
larvae ? in the laboratory, and these findings show the fungi have potential to be

More research is already underway, and as part of his PhD studies Will is examining
