e0“The efficacy of Metarhizium anisopliae DAT F-001 against Adoryphorus couloni was examined over 4 years on a sheep grazing property ('Inverell') in central Tasmania”
e1“Application of 5.1 0.7 104 M. anisopliae spores g-1 of soil (2 cm below the soil surface), during midwinter 1989, when the primary population was in the middle of the L3 larval stage, resulted in 30.3% fewer larvae in treated plots by 21 weeks and 57.8% less pupae by 27 weeks”
e2“Reductions in larval numbers led to a greater retention of sown perennial grasses, reduced weed invasion and a 23% increase in pasture productivity in the autumn of 1992”

Other claims from this paper (13)
- Association Metarhizium anisopliae application in midwinter 1989 resulted in 30.3% fewer Adoryphorus couloni larvae in treated plots by 21 weeks.
- Association In the first subsequent generation, Metarhizium anisopliae treatment gave 63.2% fewer Adoryphorus couloni larvae in 1991.
- Association In the second subsequent generation, Metarhizium anisopliae treatment gave 45.0% fewer Adoryphorus couloni larvae in 1993.
- Intervention effect Metarhizium anisopliae treatment gave 68% fewer larvae of the overlapping Adoryphorus couloni population in 1990 than untreated plots.
- Intervention effect Metarhizium anisopliae treatment gave 65% fewer larvae of the overlapping Adoryphorus couloni population in 1992 than untreated plots.
- Method / resource The Adoryphorus couloni population decline was consistent with a mortality model developed from laboratory data.
- Association Incorporating Metarhizium anisopliae into the soil did not reduce the numbers of non-target invertebrates.
- Association Reductions in larval numbers led to a greater retention of sown perennial grasses.
- Association Reductions in larval numbers reduced weed invasion in sown perennial grasses.
- Association Reductions in larval numbers were followed by a 23% increase in pasture productivity in autumn 1992.
- Observation The level of Metarhizium anisopliae DAT F-001 in the pasture remained close to the applied concentration.
- Association The level of Metarhizium anisopliae DAT F-001 in the pasture increased 10-fold when mummified cadavers were present from January to June 1990.
- Observation The level of the fungus in the soil was still twice the original applied concentration in March 1992.
