Insect Chemosensory Systems: Morphological, Molecular Biological and Neurobiological Basis Underlying Chemoreception-Guided Behaviors

Dear Colleagues,

Olfaction and gustation serve as pivotal chemosensory modalities in insect life cycles, such as foraging, mating and reproduction. To date, extensive studies have demonstrated the morphological architectures, molecular mechanisms and neurobiological organizations of insect olfaction and gustation in a broad range of insect species, such as model organisms, pathogen vectors and agricultural insects. Moreover, the chemoreception-guided interspecific and intraspecific interactions have also been widely documented in different ecological contexts. Insect chemoreception is largely dependent on various biological structures hierarchically. At the morphological level, it relies on sensilla housing chemoreceptor-expressing neurons. At the neural and molecular levels, chemoreceptors and neurons play a core role in signal transduction and transmission; carrier proteins also play an important role in transferring chemical compounds. This Special Issue aims to increase our knowledge of chemoreception-driven insect behaviors. We welcome original research papers as well as reviews covering, but not limited to, the morphological and neurobiological basis, molecular mechanisms of insect behaviors and the ecological outcomes of chemoreception-driven interspecific and intraspecific interactions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Insects is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
