A new approach to quantify semiochemical effects on insects based on energy landscapes.

<h4>Introduction</h4>Our ability to document insect preference for semiochemicals is pivotal in pest control as these agents can improve monitoring and be deployed within integrated pest management programmes for more efficacious control of pest species. However, methods used to date hav...
