AI Article Synopsis

  • Animals detect odors from mates and resources early on, which is crucial for their survival.
  • Changes in how insects move in response to these odors help them find essential resources from long distances and then search locally.
  • The review focuses on the diverse ways insects adapt their movement based on the distance to odors, highlighting differences in movement strategies and the neural circuits that control this behavior.

Article Abstract

Odors released from mates and resources such as a host and food are often the first sensory signals that an animal can detect. Changes in locomotion in response to odors are an important mechanism by which animals access resources important to their survival. Odor-modulated changes in locomotion in insects constitute a whole suite of flexible behaviors that allow insects to close in on these resources from long distances and perform local searches to locate and subsequently assess them. Here, we review changes in odor-mediated locomotion across many insect species. We emphasize that changes in locomotion induced by odors are diverse. In particular, the olfactory stimulus is sporadic at long distances and becomes more continuous at short distances. This distance-dependent change in temporal profile produces a corresponding change in an insect's locomotory strategy. We also discuss the neural circuits underlying odor modulation of locomotion.
