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. Expand
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. Expand
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. Expand
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. Expand
The complete sequence of the mitochondrial genome of the honeybee ectoparasite mite Varroa destructor (Acari: Mesostigmata).
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. Expand
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. Expand
Sequence Variation of Ribosomal Internal Transcribed Spacers (ITS) in Commercially Important Phytoseiidae Mites
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. Expand
Mity model: Tetranychus urticae, a candidate for chelicerate model organism.
The two-spotted spider mite Tetranychus urticae has the smallest genome of any arthropod determined so far, undergoes rapid development and is easy to maintain in the laboratory, which makes it a promising reference organism for the economically important, poorly studied and species-rich chelicerate lineage. Expand
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 honeyExpand
Genes in new environments: genetics and evolution in biological control
The availability of new genetic technologies has positioned the field of biological control as a test bed for theories in evolutionary biology and for understanding practical aspects of the releaseExpand
