Abstract
In recent years, the use of natural extracts has been an alternative in the control of pest insects in the search for a balance between the environment, production and the human being (Molina 2001). In the present work the objective was to conduct a study of the effectiveness of two aqueous extracts of the aromatic plants ruda and epazote as well as a combination of both for the control of white flies. The trial was done under a completely randomized experimental design with three treatments and ten laboratory repetitions. The tests were carried out on bean leaves infested with white flies and placed in Petri dishes covered with anti-aphids mesh, which were sprayed with undiluted extracts. Subsequently, a statistical analysis was carried out by means of an ANOVA and comparison test of means with the data thrown based on the number of dead flies. The study showed that the treatment developed by the combination of ruda and epazote extracts was the most effective. This study was carried out with the purpose of making contributions as an alternative for the natural control of bemisia tabaci.
