Abstract
Eriophyoid mites (Acari Eriophyoidea) are phytophagous arthropods forming intimate relationships with their host plants. These mites are associated with annual and perennial plants including ferns, and are highly specialized with a dominant monophagy. They can be classified in different ecological classes, i.e., vagrant, gall-making and refuge-seeking species. Many of them are major pests and some of them are vectors of plant pathogens. This paper critically reviews the knowledge on eriophyoids of agricultural importance with emphasis on sources for host plant resistance to these mites. The role of species belonging to the family Eriophyidae as vectors of plant viruses is discussed. Eriophyoid-host plant interactions, the susceptibility within selected crops and main host plant tolerance/resistance mechanisms are discussed. Fundamental concepts, subjects, and problems emerged in this review are pointed out and studies are suggested to clarify some controversial points.
Highlights
Eriophyoids are obligatory plant feeders with unusual morphological, biological and behavioral specialization compared to other Acari (Skoracka et al, 2010)
Some species of the family Eriophyidae can transmit plant viruses. They belong to seven genera within the subfamilies Eriophyinae, Phyllocoptinae and Cecidophyinae and have vagrant [A. hystrix, Aceria cajani Channabasavanna, Aceria ficus (Cotte), A. tosichella, Aculus cercidis (Hall)], refuge-seeking (A. tulipae, Eriophyes insidiosus Keifer and Wilson, Phyllocoptes fructiphilus Keifer, P. gracilis (Nalepa) and gall-making behavior (C. ribis, Co. vitis, Eriophyes inaequalis Wilson and Oldfield, E. pyri (Pagenstecher))
These histological reactions are in accordance with the changes induced by Fragariocoptes setiger (Nalepa) in the expression of transcription factors involved in meristem activity, plant hormone secretion, cell mitosis and adaxial–abaxial galled leaf polarity during gall morphogenesis on Fragaria viridis Weston (Paponova et al, 2018), demonstrating a complex biochemical network which has to locally restrain the mite
