Blackflies, known to the locals as “carmelitos”, are invasive pests. These flies are increasingly interfering with agriculture, have prevented tourist development in the San Cristóbal highlands, and are known elsewhere to be Onchocerciasis (River Blindness) vectors. Our team has created a comprehensive report on what is known about the carmelitos and proposed an experimental treatment plan using Bti to the Agencia de Regulación y Control de la Bioseguridad y Cuarentena Para Galápagos (ABG). We are aiming to work with farmers and governmental organizations to reduce the blackfly population and prevent the spread of these pests.
