“…Sap-feeding insects comprise a number of important taxonomic groups including aphids, whiteflies, psyllids, planthoppers, and leafhoppers. They feed using specialised feeding structures (stylets) to penetrate the plant epidermis; the insect stylet then probes through the plant mesophyll tissue towards the vascular tissue where a feeding site is established 12 . After successfully establishing a feeding site in the vascular tissue they syphon away plant nutritional resources by ingesting plant sap (usually phloem or xylem) 12 .…”

After successfully establishing a feeding site in the vascular tissue they syphon away plant nutritional resources by ingesting plant sap (usually phloem or xylem) 12 . Sap-feeding insects can cause a significant amount of plant damage through two avenues 1,2,11 : 1) Direct plant damage caused during the probing and feeding process; and 2) indirect damage caused by the transmission of phytopathogens and phytoviruses.…”

Sap-feeding insects cause significant yield losses to the world’s crops, these insects feed using syringe-like mouthparts and electrophysiology can be used to compare feeding behaviour on susceptible and resistant plants to identify the mechanistic processes behind resistant phenotypes. Data extracted from 129 studies, comprising 41 insect species across eight insect taxa and 12 host-plant families representing over 30 species, demonstrates that mechanisms deployed by resistant plants have common consequences on the feeding behaviour of diverse insect groups. We show that insects feeding on resistant plants take longer to establish a feeding site and have their feeding duration suppressed two-fold compared with insects feeding on susceptible plants. Our results reveal that the underlying traits contributing towards resistant phenotypes are conserved across plant families, deployed against taxonomically diverse insect groups, and that the underlying resistance mechanisms are conserved. These findings provide new insight that will be beneficial when developing future crop varieties.

Despite their abundance and economic importance, the mechanism of plant resistance to sap-feeding insects remains poorly understood. Here we deploy meta-analysis and data synthesis methods to evaluate the results from electrophysiological studies describing feeding behaviour experiments where resistance mechanisms were identified, focussing on studies describing host-plant resistance and non-host resistance mechanisms. Data were extracted from 108 studies, comprising 41 insect species across eight insect taxa and 12 host-plant families representing over 30 species. Results demonstrate that mechanisms deployed by resistant plants have common consequences on the feeding behaviour of diverse insect groups. We show that insects feeding on resistant plants take longer to establish a feeding site and have their feeding duration suppressed two-fold compared with insects feeding on susceptible plants. Our results reveal that traits contributing towards resistant phenotypes are conserved across plant families, deployed against taxonomically diverse insect groups, and that the underlying resistance mechanisms are conserved. These findings provide a new insight into plant–insect interaction and highlight the need for further mechanistic studies across diverse taxa.
