Recent studies have shown that certain host populations of the cereal rust mite Abacarus hystrix are highly specialized in their host use and it is likely that reproductive isolation exists between them. Here I verified this expectation by testing for reproductive barriers between ryegrass and quackgrass populations of A. hystrix. I performed reciprocal crosses between individuals from both populations and observed results of crosses. Leaves of the three grass species, ryegrass, quackgrass and… 

Quackgrass- and ryegrass-adapted populations of the cereal rust mite, Abacarus hystrix (Acari: Eriophyidae), differ in their potential for wheat, Triticum aestivum, colonization.

Quackgrass- and ryegrass-adapted strains of the cereal rust mite have different physiological host ranges and phylogenetic relationships between host plant species appear to be drivers for host specialization in this mite species.

Reproductive barriers between two sympatric beetle species specialized on different host plants

Both ecological and intrinsic factors may contribute to speciation between these species, and the genetic basis of preference and performance was at least partially independent, and several loci coded for preference, which limits the possibility of sympatric speciation.

The cereal rust mite Abacarus hystrix (Acari: Eriophyoidea) is a complex of species: evidence from mitochondrial and nuclear DNA sequences

The phylogenetic trees obtained with the maximum likelihood analysis of both COI and D2 region data sets showed that host-adapted strains of A. hystrix form distinct clades and that brome-associated strain is polyphyletic in origin.

The wheat curl mite Aceria tosichella (Acari: Eriophyoidea) is a complex of cryptic lineages with divergent host ranges: evidence from molecular and plant bioassay data

It is revealed that A. tosichella is not a homogeneous species comprising polyphagous panmictic populations rather it is a complex of genetically distinct lineages with variable host ranges and therefore variable pest potential.

Biology of Leipothrix dipsacivagus (Acari: Eriophyidae), a candidate for biological control of invasive teasels (Dipsacus spp.)

The results of this study suggest that fertilization status of L. dipsacivagus females can affect both their own fecundity and the development of their male progeny.

Spatial and Host-Related Variation in Prevalence and Population Density of Wheat Curl Mite (Aceria tosichella) Cryptic Genotypes in Agricultural Landscapes

The results of this research identify high-risk areas for the presence of the most pestiferous WCM lineages in the study area (viz. the entirety of Poland) and provide insight into the evolution of pest species of domesticated crops and facilitate testing of fundamental hypotheses about the ecological factors that shape this pest community.

Integrative taxonomy of Abacarus mites (Eriophyidae) associated with hybrid sugarcane plants, including description of a new species

Presenting the occurrence of multiple Abacarus species associated with sugarcane, contributes to the knowledge on plants and mites diversity by adding up one more clue highlighting that plant hybridization can be an important mechanism contributing to the speciation of plant-feeding arthropods.

Host-plant specificity and specialization in eriophyoid mites and their importance for the use of eriophyoid mites as biocontrol agents of weeds

Testing the actual host range of a given eriophyoid species, searching for ecological data, genetic differentiation analysis, and recognizing factors and mechanisms that contribute to host specificity of eriophical mites are suggested as future directions for research.

Cryptic species within the wheat curl mite Aceria tosichella (Keifer) (Acari : Eriophyoidea), revealed by mitochondrial, nuclear and morphometric data

Investigation of WCM populations from different host plants in Australia, South America and Europe and molecular datasets suggest that what has been recognised historically as a single species is, in fact, a complex of several genetically isolated evolutionary lineages that demonstrate potential as cryptic species.

Cryptic diversity within grass-associated Abacarus species complex (Acariformes: Eriophyidae), with the description of a new species, Abacarus plumiger n. sp.

It is demonstrated that cryptic speciation occurs in the grass-associated Abacarus genus, and the need for more extensive sampling using integrative methods is suggested, and a pattern of host-associated differentiation within the complex is demonstrated.



Is the Cereal Rust Mite, Abacarus Hystrix Really a Generalist? – Testing Colonization Performance on Novel Hosts

The main conclusion is that A. hystrix, which so far has been considered as a host generalist, in fact may be a complex species consisting of highly specialized host races.

Host related differences in the development and reproduction of the cereal rust mite, Abacarus hystrix (Acari: Eriophyidae) in poland

The hypothesis that the two populations of this mite from E. repens and L. perenne are highly specialized in their host use and may be regarded as host races or separate species is supported.

Lack of Evidence for Reproductive Isolation among Ecologically Specialised Lycaenid Butterflies

The potential role of host plant fidelity in the evolution of reproductive isolation was examined in a pair of North American blue butterfly species, Lycaeides idas and L. melissa, which appear to be undergoing adaptive radiation driven at least partially by host shifts.

H hierarchical estimates of population structure based on Fst suggest that gene exchange between closely adjacent aphid populations on the two hosts is highly restricted relative to that among fields of the same host plant.

This work synthesizes studies of Timema cristinae host plant ecotypes to compare the magnitude of multiple reproductive barriers among different ecological and geographic scenarios and revealed that divergent host adaptation can promote the evolution of diverse reproductive barriers, including those that are not inherently ecological.

Host fidelity is an effective premating barrier between sympatric races of the apple maggot fly.

The results verify that host-associated adaptation can produce reproductive isolation as a correlated character (a key premise of sympatric speciation) and represents one of the few or perhaps only example in animals where the intra-specific isolating effects of specific phenotypes have been quantified in nature.

Divergent Host Acceptance Behavior Suggests Host Specialization in Populations of the Polyphagous Mite Abacarus hystrix (Acari: Prostigmata: Eriophyidae)

The hypothesis of narrow host specialization of ryegrass and quackgrass populations of this highly polyphagous mite is supported and mites of these two studied populations can quickly distinguish between their familiar host and an unfamiliar host used by a conspecific.

Morphological variation in different host populations of Abacarus hystrix (Acari: Prostigmata: Eriophyoidea)

Analysis of canonical loadings showed that traits, which bestdiscriminate the populations living on different hosts, are: body elongation, length of setae and overall body size, which areinterpreted in terms of adaptation to specific environmental conditions created by the host.

Genetic differentiation in Zeiraphera diniana (Lepidoptera: Tortricidae, the larch budmoth): polymorphism, host races or sibling species?

Phenological differences between the two hosts, together with the great vagility of Z. diniana, an outbreak pest, suggest that sympatric or parapatric differentiation is at least as likely as allopatric divergence.

The objective of this paper is to point out how the biological attributes of these flies may have permitted new forms to arise rapidly in the absence of geographical barriers to gene flow.
