Abstract

Most volatile semiochemicals and essential oils used in pest monitoring and control are sensitive molecules and can be degraded by the action of light and oxygen. For the protection of bioactive molecules there has been a growing use of formulations with inert and biodegradable materials that should ensure controlled release of the bioactive compound. Commercially available pheromone releasers vary greatly in the capacity of material released and are generally influenced by environmental conditions. An alternative is the application of microencapsulation, which consists of incorporating the bioactive material into a matrix that is capable of conferring to the encapsulated the desired protection and release characteristics to be applied in Integrated Pest Management (IPM). Aiming to obtain a matrix that allows the protection of the essential oil of the fruit of S. terebinthifolius (pink pepper) optimizing its shelf life and its release in a controlled, realized experiments of microencapsulation with this essencial oil. The essential oil of pink pepper was obtained by the hydrodistillation technique, and the microcapsules were obtained by the spray drying technique having as nucleus the oil and as encapsulating agents maltodextrin and gum arabic. The microcapsule morphology was analyzed by Scanning Electron Microscopy (SEM) and its thermal stability was tested by Thermogravimetry (TG). Microcapsules containing the essential oil of S. terebinthifolius in its nucleus presented repellent activity to Lasioderma serricorne similar to the activity of pure essential oil, showing that these microparticles can be used as liberators.
