The effectiveness of the Metarhizium anisopliae (Metschinkoff) Qu-M845 isolate was evaluated in laboratory and field trials. It was previously selected for thermal resistance (at 30 and 35 ºC) and pathogenicity on Varroa destructor (Anderson and Trueman). In the laboratory, the first evaluations were carried out by spraying and increasing the concentration from zero to 108 conidia mL-1 on varroa adults. Lethal concentrations required for 50 and 90% mite mortality (LC50 and LC90) were 3.8 x 105 and 8 x 107 conidia mL-1, respectively (χ2 = 2.03). In the autumn field trials, three application methods (doses of 5 x 1010 conidia per hive) were evaluated. The treatments were: a) conidia stamped on filter paper, located on every second frame i...
