The genome of Tetranychus urticae reveals herbivorous pest adaptations
The completely sequenced and annotated spider mite genome is presented, representing the first complete chelicerate genome, and finds strong signatures of polyphagy and detoxification in gene families associated with feeding on different hosts and in new gene families acquired by lateral gene transfer.
Species-wide homogeneity of nuclear ribosomal ITS2 sequences in the spider mite Tetranychus urticae contrasts with extensive mitochondrial COI polymorphism
It is argued that rDNA homogeneity over the species range of T. urticae results from the high colonization potential of this species, preventing long-term differentiation.
Differential gene expression of the honey bee Apis mellifera associated with Varroa destructor infection
Differences in behavior, rather than in the immune system, underlie Varroa tolerance in honey bees, and provide a first step toward better understanding molecular pathways involved in this important host-parasite relationship.
Mitochondrial cytochrome oxidase I in tetranychid mites: a comparison between molecular phylogeny and changes of morphological and life history traits
Part of the mitochondrial cytochrome oxidase subunit I (COI) gene is sequenced in 20 species of phytophagous mites belonging to nine genera and two families, including several agricultural pests, and the phylogeny based on COI sequences was inferred using the maximum likelihood method.

The level of sequence variation of the nuclear ribosomal spacers ITS 1 and 2 and the 5.8S gene in six species of Phytoseiidae mites is investigated and it is found that the value of ITS in taxonomic studies does not extend to the level of the family.
The invasive Korea and Japan types of Varroa destructor, ectoparasitic mites of the Western honeybee (Apis mellifera), are two partly isolated clones

The existence of F1 and recombinant individuals in admixed populations requires that double infestations of honeybee cells occur in a high proportion but the persistence of pure types suggests a post–zygotic isolation between the two clones.

Complete mitochondrial genome sequences are now available for 28 Arthropoda (see references at), more than for any other invertebrate phylum, and major rearrangements in the gene order were found for two of these ticks: R. sanguineous and B. microplus.
Intraspecific diversity of the Cassava Green Mite Mononychellus progresivus (Acari: Tetranychidae) using comparisons of mitochondrial and nuclear ribosomal DNA sequences and cross-breeding

The data support the hypothesis of a single introduction of the species in the two African populations and show the usefulness of molecular markers as a tool for determining taxonomic status and dispersion paths in spider mites.
Test of Colonisation Scenarios Reveals Complex Invasion History of the Red Tomato Spider Mite Tetranychus evansi
This study illustrates that ABC methods can provide insights into, and distinguish among, complex invasion scenarios, and is critical not only in understanding the biology of invasions, but also in refining management strategies for invasive species.
New Asian types of Varroa destructor: a potential new threat for world apiculture
The invasion of the Western honey bee, Apis mellifera, by Varroa destructor is attributed to two mitochondrial haplotypes (K and J) that shifted last century from their primary host the Eastern honey…
