Aphids are key pests of crop plants throughout the world because they pose serious threats to crop production. As phloem-feeding insects, aphids suck plant juices and secrete sticky “honeydew”, causing serious damage to the host plants. Fortunately, some plants often can withstand aphid feeding with no adverse effect. These plants can mount a successful defense using their natural genetics or alter the ways they interact with aphids; thus, host plant resistance has been used for effective aphid control in many crops. Interactions between plants and aphids happens in parallel or as coevolution, leading to the development of their new relationship, under which aphids must evolve innovative ways to feed and colonize on their hosts, whereas plants must develop novel compounds, express special gene(s) or modify the regulatory mechanisms to defend against aphids. The mechanisms of plant defense against aphids are complicated, highly dynamic, and wide-ranging and involve direct and indirect defenses. Recent studies of plant-aphid interactions by comparing transcriptomic, proteomic, and metabolomic data led to identification of key genes, proteins, and chemical compounds derived from the plant-aphid interactions, which offer new insight into the molecular mechanisms of plant defense against aphids. The Special Issue welcomes papers on various aspects of plant-aphid interactions, particularly on molecular mechanisms.

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. 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.
