(Submitter supplied) We identified and characterized a striking case of multiple acaricide resistance in a field population of T. urticae. Exceptionally strong resistance phenotypes, with accumulation of multiple resistance mutations and over-expression of P450s and other detoxification genes in the same field population is reported.

(Submitter supplied) We performed expression quantitative trait locus (eQTL) mapping between two strains of Tetranychus urticae (the two-spotted spider mite), a generalist herbivore known for its rapid evolution of acaricide resistance. For parents, we used the inbred strain MR-VPi that is highly resistant to multiple acaricides in different classes, and the inbred strain ROS-ITi that is comparatively susceptible to many acaricides. more...

(Submitter supplied) While performing mitochondrial isolations and recently developed tRNA-seq methods (AlkB treatment and YAMAT-Seq) in plant tissue, we inadvertently sequenced the mitochondrial tRNAs from a common plant pest, the acariform mite Tetranychus urticae, to a high enough coverage to detect all previously annotated T. urticae tRNA regions. The results not only confirm expression, CCA-tailing and post-transcriptional base modification of these highly divergent tRNAs, but also revealed paired sense and antisense expression of multiple T. more...

(Submitter supplied) No major transcriptomic differences were observed between JPR-R1/2 and JPR when strains were not exposed to pyflubumide. Only three genes (tetur13g01730, tetur14g03160, and tetur14g01700) were consistently up-regulated in JPR-R1/2, but none coded for enzymes that are known to be associated with xenobiotic metabolism. As a next step, we used the original and susceptible JPO strain, the parent of JPR, as a reference to investigate transcriptomic changes. more...

(Submitter supplied) Macrocylic lactones, milbemectin and abamectin, are compounds that are frequently used for the control of the two-spotted spider mite Tetranychus urticae. The development of abamectin resistance in this major pest has become an increasing problem worldwide, potentially compromising the use of milbemectin. In this study, gene expression profile differences between abamectin/milbemectin resistant T. urticae populations (ES1, IT2 and UK6) and a susceptible T. more...

(Submitter supplied) The citrus red mite, Panonychus citri, is a major pest on citrus all around the world. Mitochondrial Electron Transport Inhibitors of complex I (METI-I) acaricides such as fenpyroximate have been used extensively to control P. citri populations, which resulted in multiple reports of METI-I resistant populations in the field. In this study, gene expression profile differences between METI-I resistant P. more...

(Submitter supplied) In this study, we show that in a spider mite species, Tetranychus urticae, genetic changes do not drive experimental range expansions. We performed two experiments, each with two treatments, wherein mite populations were allowed to expand their habitat range. In a first experiment, we either replaced migrating females with females from the parental stock populations (Replacement From Stock) or left the migrants unmanipulated (Control). more...

(Submitter supplied) Synergists can counteract metabolic insecticide resistance by inhibiting detoxification enzymes or transporters. In this study we used Illumina RNA-sequencing to investigate genome-wide transcriptional responses in an acaricide resistant strain (JP-R) of the spider mite Tetranychus urticae upon exposure to synergists such as S,S,S-tributyl phosphorotrithioate (DEF), diethyl maleate (DEM), piperonyl butoxide (PBO) and cyclosporin A (CsA).

(Submitter supplied) Genome annotation of the chelicerate Tetranychus urticae revealed the absence of many canonical immunity genes. T. urticae either does not mount an immune response or it induces uncharacterized immune pathways. To disentangle these two hypotheses, we performed transcriptomic analysis of mites injected with bacteria vs mites injected with LB-buffer. Two types of bacteria were injected: E. coli and B. more...

(Submitter supplied) Sex-specific differences in gene expression underlie differences in morphology, behavior, and reproduction. To date, little is known about sex-specific differences in gene expression in spider mites, even though males and females differ markedly in morphology and behavior. In this study, we describe the complement of sex-specific gene expression differences between males and females of the two-spotted spider mite (Tetranychus urticae), an important generalist herbivore that is a significant crop pest. more...

(Submitter supplied) Proteins produced in the salivary glands of arthropod herbivores can function as effectors to modify plant defense responses. To obtain a set of candidate, salivary gland specific genes for the mite herbivore Tetranychus urticae, mites were dissected and the head region was recovered. Specifically, the proterosoma was dissected from 250 mites. This includes the salivary glands, and other nearby tissue (given their small size, exact micro-dissection of salivary glands was not possible). more...

(Submitter supplied) A genetically diverse strain (labelled as London) of the phytophagous mite Tetranychus urticae was transferred from its common host (bean) to other host plants (cotton, maize or soy). Three different host plant species were included in the experimental set-up: cotton (Gossypium spp.), maize (Zea mays cv. Ronaldinio) and soy (Glycine max cv. Merlin). Five generations after host-transfer, total RNA of all mite populations (London, London-SOY, London-MAIZE and London-COTTON) was collected and used in a genome-wide gene expression microarray (Sureprint G3 microarray, Agilent) Microarray analysis revealed large-scale differential expression of genes coding for enzymes of detoxification families, secreted proteins with unknown functions and regulatory enzymes.

(Submitter supplied) In this study, we profiled the transcriptional changes in a polyphagous spider mite, Tetranychus urticae, after adaptation to spatial and tempospatial stress. We show heritable down-regulation of genes encoding for core enzymes involved in the citric acid and gluconeogenesis/glycolyse pathways (glucose 6-phosphatase among others). Additionally, we observe heritable transcriptional changes in amino acid pathways (methionine, tyrosine and phenylalanine) and in laterally acquired genes from bacteria (cobalamin-independent methionine synthase). more...
