The 20th European Society for Vector Ecology Conference 2016 wants to draw attention to the impact and importance of vectors and vector-borne diseases on landscapes inhabited by human beings and how to make this paradigm most effective to benefit public health. Session subjects are: invasive species: ecology and their potential role as vectors; citizen science and social approaches on vector control; epidemiology of vector-borne diseases and their vectors; ecology and behaviour of vectors; emerging vector-borne diseases and risk assessment; vector-pathogens interactions; taxonomy, systematic and phylogeny of vectors; and advance technologies on vector control.The 20th European Society for Vector Ecology Conference 2016 wants to draw attention to the impact and importance of vectors and vector-borne diseases on landscapes inhabited by human beings and how to make this paradigm most effective to benefit public health.
