Physical processes and real-time chemical measurement of the insect olfactory environment.

摘要: Odor-mediated insect navigation in airborne chemical plumes is vital to many ecological interactions, including mate finding, flower nectaring, and host locating (where disease transmission or herbivory may begin). After emission, volatile chemicals become rapidly mixed diluted through physical processes that create a dynamic olfactory environment. This review examines those some of the analytical technologies available characterize behavior-inducing signals at temporal scales equivalent processing insects. In particular, we focus on two areas research together further our understanding signal dynamics its perception by First, measurement atmospheric field can provide insight into spatiotemporal odor Field measurements turn permit aspects environment be simulated laboratory, thereby allowing careful investigation links between behavior. Second, emerging with high recording frequencies field-friendly inlet systems offer new opportunities natural odors relevant Characterization allows determination when where olfactory-mediated behaviors control interactions. Finally, argue coupling these will foster increased physicochemical enable researchers determine how environments shape sensory systems.
