| The natural insect host range of the entomopathogenic fungi (EPF) Beauveria bassiana (Bb) and Metarhizium anisopliae (Ma) was investigated in Argentina during the winter of 2003 through spring of 2004. Fungi- infected insect samples (153) were collected from cornfields and the surrounding uncultivated areas in different localities of Buenos Aires (7), Tucumán (2), and Corrientes (3) provinces. The rates of Bb-infected host range varied among the Coleoptera (37%), Hemiptera (27%) and Dermaptera (1.3%). While the rates of Ma-infected host range varied between the Coleoptera (0.7%) and Hemiptera (34%). The greater host range resulted with B. bassiana found from eight species of Coleoptera (four families), one species of Dermaptera and four species of... |
