The Chemistry of Insect-Plant Interaction

Dear Colleagues,

Phytochemical variation among plant species is one of the most fascinating features of the natural world, and has implications for the functioning of ecosystems. A key area of phytochemical variation research has focused on insects that feed on plants (pollinators and herbivores), as well as the enormous diversity of plant-derived compounds that reduce or deter damage by insects. Empirical studies on the ecology and evolution of these chemically mediated plant–insect interactions have been guided by a long history of theoretical development. Secondary metabolites can accumulate to significant levels within the tissues of plants undergoing a herbivore attack. These can act as attractants and repellents, causing physiological and morphological changes in insects, capable of inhibiting food consumption by larvae, as well as reducing larval emergence and reducing or blocking female oviposition, or even as attractive agents (aroma, color, and flavor) for pollinators. The secondary metabolites of plants are related to the evolution of the species, playing an important role in the adaptation of plants to their environments and defining the survival capacity of each plant species. The variety of selective pressures faced by plants throughout their history influences the vast diversity of secondary metabolites. Secondary metabolites gain prominence with the multiple discoveries of their functions in plants, mainly as food deterrents, defense against herbivores, and attraction for pollinators, among others. The objective of this research topic is to analyze the role of secondary metabolites in insect–plant interaction, with an emphasis on herbivory and pollination. In this research topic, we invite the submission of articles focusing on all types of plant–insect interaction, evaluating the chemical compositions of plants and their relationships in this interaction.

We welcome all types of articles published by Agronomy that contribute to (but are not limited to) the following topics:

• Insect–plant interactions: the abilities of each;
• From insect–plant interactions to ecological networks;
• Volatile organic compounds from plants: revealing interactions;
• Chemical compounds involved in communication between plants and floral visitors;
• The chemistry of pollination;
•  Allelochemicals and chemical signalers in plants to insects.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agronomy 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.
