Abstract

Insects of the genus Culicoides are considered pests for transmitting diseases of veterinary (Bluetongue, Schmallenberg, African Horse Sickness) and human (Oroupoche), causing various economic impacts, damage to health, as well as harming economic and social development. Control of these insects is currently limited to four control approaches: mechanical, chemical, biological and genetic. Insecticides are most commonly used in areas where they occur most. This study aimed to identify volatile organic compounds (VOCs) that are released by sheep (males and females), seeking an alternative control, less environmentally harmful and based on chemical ecology. For this, the VOCs of 12 crossbred sheep (Santa Inês X Dorper) were captured at Federal Institute of Alagoas, Satuba / AL. After the capture and extraction, the VOCs were subjected to gas chromatography and mass spectrometry - coupled gas chromatography analyzes for identification. After the analysis of all the chromatographic profiles of the VOCs from the studied sheep, were identified 23 VOCs belonging to the functional groups: alkanes, ketones and aldehydes. These VOCs were common to all of animals studied. In addition, the analyzes indicated that the number of VOCs released by males was higher when compared to the number of VOCs from females, during the same analysis time. The results of the analysis showed the existence of VOCs, with the potential of attracting Culicoides, giving subsidies to the elaboration of baits for the control of these insects.
