Insect olfaction

More about the book

Research on insect olfaction is crucial for two main reasons. First, the olfactory systems of insects and their arthropod relatives serve as favorable models for studying general olfactory principles applicable to both vertebrates and invertebrates. Detailed comparisons of olfactory pathways in these groups have uncovered significant similarities in functional organization, physiology, and development, indicating that the neural mechanisms for processing olfactory information are more alike than different, despite evolutionary distances. Second, the significance of insect olfaction extends to its economic and medical implications, given that insects can be agricultural pests and disease vectors, while beneficial species like bees and moths play vital roles in pollination and honey production. The impact of an insect—whether harmful or beneficial—depends on its behavior, which is largely influenced by sensory information. Olfaction often serves as the primary sensory modality guiding essential insect behaviors, such as orientation, movement towards mates, oviposition sites, and food sources. Consequently, much research in this field aims to leverage insights from insect olfaction to develop strategies for managing harmful species and promoting the welfare of beneficial ones.
