Marcelo Lorenzo’s event: ‘Behaviour of Arthropod Disease Vectors: A Source for Biorational Pest Control in a One Health Context

4-5 July 2022

The enormous impact of human activities on ecosystems is the hallmark of the Anthropocene. Changes in landscape, land use and agricultural practices, globalization, environmental pollution, pesticide abuse, and climate change are main drivers of infectious disease emergence or re-emergence. In this context, it becomes clear that controlling disease vectors requires deeper knowledge of arthropod biology on which to base integrated strategies taking into account potential environmental impacts and sustainability.

We will meet in Montpellier to promote a rich exchange on state-of-the-art arthropod vector neuroethology and control in the context of the increasing awareness associated with the impacts of the Anthropocene. Our aim is to generate new perspectives for developing sustainable pest control strategies based on arthropod behavioral manipulation within a One Health context.
