The cereal rust mite Abacarus hystrix (Nalepa), a significant pest of grasses, has been regarded as one of a few exceptions among eriophyoid mites with reference to the pattern of host plant utilization. At least 60 grass species have been recorded as its hosts. Thus, the mite has long been considered as a host generalist in which host specialization would(More)
The present systematic classification of Eriophyoidea is widelyrecognised as artificial and not reflecting plant-herbivore linkage.Quantitative description of host-related morphological variation can providethebasic information needed to improve the eriophyoid taxonomic system and enhanceour understanding of mechanisms generating this variation. The purpose(More)
The wheat curl mite (WCM) is a major pest in cereal crops around the world and the vector of at least four known pathogens capable of reducing yields in crops such as wheat, corn, barley, oats, millet and rye. Current taxonomy recognizes WCM as a single species, Aceriatosichella; however, recent genetic, physiological and ecological studies have shown that(More)
Eriophyoid species belonging to the genus Trisetacus are economically important as pests of conifers. A narrow host specialization to conifers and some unique morphological characteristics have made these mites interesting subjects for scientific inquiry. In this study, we assessed morphological and genetic variation of seven Trisetacus species originating(More)
Host race formation generates diversity within species and may even lead to speciation. This phenomenon could be particularly prevalent in the Acari due to the often intimate interaction these species have with their hosts. In this review, we explore the process of host race formation, whether it is likely to occur in this group and what features may favour(More)
The wheat curl mite (WCM), Aceria tosichella, and the plant viruses it transmits represent an invasive mite-virus complex that has affected cereal crops worldwide. The main damage caused by WCM comes from its ability to transmit and spread multiple damaging viruses to cereal crops, with Wheat streak mosaic virus (WSMV) and Wheat mosaic virus (WMoV) being(More)
Eriophyoid mites are excellent candidates for ethological research using the approaches of behavioural ecology and sociobiology. These tiny haplodiploid mites are highly specialized plant parasites, producing galls, forming nests, inhabiting refuges or living freely on plants. They reproduce via spermatophores deposited on a substrate and without pairing,(More)
Eriophyoid mites, which are among the smallest plant feeders, are characterized by the intimate relationships they have with their hosts and the restricted range of plants upon which they can reproduce. The knowledge of their true host ranges and mechanisms causing host specificity is fundamental to understanding mite-host interactions, potential mite-host(More)
Demography parameters of the cereal rust mite Abacarus hystrix (Nalepa) on quack grass were studied to investigate its potential capacity of population increase in conditions of initially low density. The experiment was maintained under laboratory conditions at a constant temperature of 19.5–20.5 °C and 94 ± 1% RH. Life-history data were used to calculate(More)
