COVA, Luís José et al. Temporal control of flies (Musca domestica) in poultry sheds fogged with spores of Beauveria brongniartii. Zootecnia Trop. [online]. 2010, vol.28, n.1, pp.9-15. ISSN 0798-7269.

In order to determine the effectiveness of Beauveria brongniartii spores (Monilia: Moniliaceae) to control common flies (Musca domestica L.) through mist in the interior of sheds breeding chickens (7 chickens/m²), at doses of 9 x 10⁷ conidias/mL (15 1 prepared for each 1200 m²), an experiment was conducted in poultry units located in the vicinity of Isnotú, “Rafael Rangel” municipality, Trujillo state, Venezuela. At the start of the trial no difference in the average population of flies among the control and treated sheds were observed (P>0,05). However, statistical differences among control and treated sheds in the second (P<0,05), third (P<0,01) and fourth (P <0,001) weeks after first application were observed. The percentage of population reduction was prompted after nebulizer once a week for three weeks, 81, 31 and 100%, respectively. Results showed that under the experimental conditions B. brongniartii constitutes a viable alternative for comprehensive health control in the production units
