“…These changes in the plant are consequences of the insect's feeding. In this context, psyllids induce gall through their saliva's toxins (Sharma & Raman, 2022;Takeda et al, 2021). Jasmonic acid, its methyl ester and isoleucine conjugate (JA-Ile) are derivatives of a class of fatty acids collectively known as jasmonates (JAs), which are related to abiotic and biotic plant stress and involved in the regulation of plant growth and development (Ruan et al, 2019).…”

Assessment of Triozoida limbata (Hemiptera: Triozidae) attacks: morphological and biochemical changes on Psidium guajava plants

The relationship between herbivorous insects and plants is an example of an ‘evolutionary arms race’. Understanding the relationship between insects and their host plants makes it possible to determine critical points in the bioecology of these herbivores. In this relationship, insects and plants use strategies to overcome, avoid and mitigate the actions of the other. Insect‐induced galls are one of the great examples of this ‘arms race’. Psyllids (Hemiptera: Psylloidea) are among the most important gall‐inducing insects. The psyllid Triozoida limbata (Triozidae) is an important pest of guava (Psidium guajava) in the Neotropics. Thus, this work aimed to determine the morphological, anatomical, and biochemical changes in guava leaves caused by T. limbata to study the ‘arms race’ between these two organisms. Therefore, the process of gall formation on guava leaves during the psyllid life cycle was described. A comparative study of the anatomy and levels of phytohormones in leaves attacked and not attacked by the psyllid was carried out. It was found that the psyllid attack triggered the plant's defence by increasing the jasmonic acid content in the leaves. The psyllid attack caused anatomical changes in the leaves (such as cell non‐differentiation), allowing the insect to survive feeding on the plant. In addition, the psyllid‐induced galls provided shelter for the psyllid.

“…Psyllids have also stoked research interest due to the diverse array of phenotypes that they induce on hosts through their salivary secretions. These range from leaf curling and unique senescencelike conditions to complex gall morphologies (11,116). Genomic resources published within the past decade are helping to illuminate genes and proteins that underlie the induction of different host phenotypes.…”

“…Genomic resources published within the past decade are helping to illuminate genes and proteins that underlie the induction of different host phenotypes. This review synthesizes and highlights key advances in our understanding of psyllid behavior, host feeding, microbial interactions, and ecological roles, with a focus on freeliving psyllids that do not form galls on host plants (for reviews on gall-forming psyllids, see 116). We also point out best experimental practices and identify key priorities for future research.…”

Psyllids constitute a diverse group of sap-feeding Sternorrhyncha that were relatively obscure until it was discovered that a handful of species transmit bacterial plant pathogens. Yet the superfamily Psylloidea is much richer than the sum of its crop-associated vectors, with over 4,000 described species exhibiting diverse life histories and host exploitation strategies. A growing body of research is uncovering fascinating insights into psyllid evolution, biology, behavior, and species interactions. This work has revealed commonalities and differences with better-studied Sternorrhyncha, as well as unique evolutionary patterns of lineage divergence and host use. We are also learning how psyllid evolution and foraging ecology underlie life history traits and the roles of psyllids in communities. At finer scales, we are untangling the web of symbionts across the psyllid family tree, linking symbiont and psyllid lineages, and revealing mechanisms underlying reciprocal exchange between symbiont and host. In this review, we synthesize and summarize key advances within these areas with a focus on free-living (nongalling) Psylloidea. Expected final online publication date for the Annual Review of Entomology, Volume 69 is January 2024. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

“…The plant–insect interaction dates back to prehistorical times [ 1 ]. The evolution of plant defense responses against herbivores requires stress response-associated mechanisms, including phytohormones production [ 2 , 3 , 4 ], host specificity [ 5 ], protease inhibitor activities [ 6 , 7 ], plant volatile emission [ 8 ], phenotypic plasticity [ 9 ], cross-species communication [ 10 ], morpho-physiological and chemical reprogramming [ 11 ], response to insect-derived elicitors or effectors [ 12 , 13 ], all involving metabolic costs [ 14 ].…”

Calcium Signaling in Plant-Insect Interactions

In plant–insect interactions, calcium (Ca2+) variations are among the earliest events associated with the plant perception of biotic stress. Upon herbivory, Ca2+ waves travel long distances to transmit and convert the local signal to a systemic defense program. Reactive oxygen species (ROS), Ca2+ and electrical signaling are interlinked to form a network supporting rapid signal transmission, whereas the Ca2+ message is decoded and relayed by Ca2+-binding proteins (including calmodulin, Ca2+-dependent protein kinases, annexins and calcineurin B-like proteins). Monitoring the generation of Ca2+ signals at the whole plant or cell level and their long-distance propagation during biotic interactions requires innovative imaging techniques based on sensitive sensors and using genetically encoded indicators. This review summarizes the recent advances in Ca2+ signaling upon herbivory and reviews the most recent Ca2+ imaging techniques and methods.
