Control de pulgón de la rosa (macrosiphum rosae), con aceites esenciales en emulsión, en condiciones de laboratorio, provincia de Cotopaxi, cantón Latacunga.

The present investigation was carried out in the Entomology laboratory of the Technical University of Cotopaxi, the control of two essential oils (Ruta graveolens and Anethum graveolens) was evaluated in emulsion at three concentrations of 25%, 50%, including the control 0% for the control of Macrosiphum rosae. A Completely Random Design (DCA) was applied with an A*B factorial arrangement with six treatments and three repetitions and a total of 18 experimental units, in each experimental unit 30 individuals of Macrosiphum rosae were released, where the essential oils were applied in emulsion. Mortality data collection was performed by observation three minutes after applying the treatments, using the counting and extraction of dead individuals. In addition, the chemical composition was analyzed through gas chromatography coupled to a mass spectrometer detector in the Agilent Technologies 5975C inert XL MSD with Triple - Axis Detector equipment where various organic compounds were appreciated, with a greater presence of 2-un decanone with 46.88% in Ruta graveolens and Alfa-Tijone with 10.44% in Anethum graveolens. It is concluded that the essential oils in emulsion control Macrosiphum rosae under laboratory conditions with an average of 11.44 dead individuals of Ruta graveolens followed by 3.67 dead individuals of Anethum graveolens. The interaction between oils*concentrations, Ruta graveolens in a 50% concentration presented an average of 17.67 dead individuals three minutes after the application of the oil in emulsion.
