Effect of Beauveria bassiana and Beauveria brongniartii for the house fly (Musca domestica) control on laboratory and poultry sheds conditions

An experiment was carried out in Trujillo state, Venezuela, in laboratory and poultry sheds conditions in order to study the Beauveria brongniartii (strain: LF-05) and Beauveria bassiana (strain: LF08) pathogenicity in Musca domestica. With 1.2 x 10(7) conidiospores/mL the lethal times (TL50 and TL95) were 5 and 9, and 5 and 6 days, respectively. In field conditions spores of B. brongniartii and B. bassiana were applied inside the poultry sheds (7 chickens/m(2)) with a dose of 9 x 10(7) conidia/mL in 15L of water for each 1200 m(2), the percentage of population reduction were induced after vaporized once a week for three weeks in 13.99 and 100% for B. brongniartii; and -35,91 and 100% for B. bassiana.
