Abstract

Chrysomya albiceps (Wiedemann) is an important vector of animal and diseases as well as causer of secondary myiasis. In order to minimize the effect of the problems caused by C. albiceps, the pathogenicity of the Beauveria bassiana (Balsamo) Vuillemin (URM 3447), in vitro, over eggs, larvae and adults in acclimatized laboratorial conditions under the temperature of 28 ± 1 °C was evaluated. Suspensions of conidia (104, 105, 106, 107 and 108 conidia.mL-1) were done, for the analysis of the biological parameters. In the bioassay with eggs, the percentage of eclosion varied from 84.81 to 97.22%. In the bioassay with larvae, pre-pupa period varied from 1 to 1.04 and of pupa, from 5 to 5.09 days; the percentage of adult emergency from treated larvae varied from 30.88 to 80.82%. As to the bioassay with adults, the longevity for male and female was of 4.51 to 6.77 and 10.19 to 14.67 days, respectively; the accumulated mortality death on the 7th day varied from 47.50 to 81.20% for males and of 23.70 to 55.00% for females; the period of posture varied from 10 to17.75 days and the percentage of larvae appeared from females infected varied from 71.39 to 91.25%.
