Abstract

In order to determine the effectiveness of Beauveria brongniartii check for this species in other resources spores (Monilia: Moniliaceae check for this species in other resources ) to control common flies ( Musca domestica check for this species in other resources L.) through mist in the interior of sheds breeding chickens (7 chickens/m2), at doses of 9 x 107 conidias/mL (15 l 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.

Resumen

Con el objetivo de determinar la efectividad de esporas de Beauveria brongniartii check for this species in other resources (Monilia: Moniliaceae check for this species in other resources ) para el control de moscas doméstica ( Musca domestica check for this species in other resources L.) mediante nebulización en el interior de galpones de cría de pollos (7 pollos/m2), a dosis de 9 x 107 conidias/ml (15 l de preparado para cada 1200 m2), se llevó a cabo un experimento en unidades avícolas ubicadas en la cercanía de Isnotú, municipio Rafael Rangel, estado Trujillo, Venezuela. Se utilizaron dos tratamientos (T1: control con aplicación de placebo y T2: aplicación de suspensión del hongo a concentración fija). Al inicio del ensayo no se observaron diferencias en la media poblacional de moscas entre los galpones usados como control y los destinados al tratamiento con B. brongniartii (P <0,05); sin embargo, se observaron diferencias estadísticas entre los galpones tratados y el control en la segunda (P >0,05), tercera (P >0,01) y cuarta (P >0,001) semana post-primera aplicación. El porcentaje de reducción poblacional se indujo tras nebulizar una vez por semana, durante tres semanas, en 81; 31 y 100%, respectivamente. Los resultados permiten concluir que en las condiciones experimentales B. brongniartii constituye una alternativa viable para el control sanitario integral en las unidades de producción.
