[Ti] Título:RNAi-based reverse genetics in the chelicerate model Tetranychus urticae: A comparative analysis of five methods for gene silencing.

[Ab] Resumo:RNA interference (RNAi) can be used for the protection against agricultural pests through the silencing of genes required for pest fitness. To assess the potential of RNAi approaches in the two-spotted spider mite, Tetranychus urticae, we compared 5 methods for the delivery of double-stranded RNA (dsRNA). These methods include mite feeding on either (i) leaves floating on a dsRNA solution, (ii) dsRNA-expressing plants, (iii) artificial diet supplemented with dsRNA, or (iv) dsRNA-coated leaves, and (v) mite soaking in a dsRNA solution. In all cases, the gene targeted for method validation was the Vacuolar-type H+-ATPase (TuVATPase), encoding a constitutively expressed ATP-driven proton pump located in the membrane. Down-regulation of TuVATPase increased mortality and/or reduced fecundity in all methods, but with variable efficiency. The most efficient methods for dsRNA delivery were direct soaking of mites in the dsRNA solution and mite feeding on dsRNA-coated leaves that mimics dsRNA application as a sprayable pesticide. Both resulted in a dark-body phenotype not observed in mites treated with a control dsRNA. Although with lower efficiency, dsRNA designed for TuVATPase silencing and expressed in transgenic Arabidopsis plants impacted the fitness of mites feeding on these plants. RNAi may thus be a valuable strategy to control spider mite populations, either as a sprayable pesticide or through transgenic crops. This comparative methodological study focusing on the induction of RNAi-based gene silencing in T. urticae paves the way for reverse genetics approaches in this model chelicerate system and prepares large-scale systematic RNAi screens as a first step towards the development of specific RNA-based pesticides. Such alternative molecules may help control spider mites that cause significant damages to crops and ornamental plant species, as well as other chelicerates detrimental to agriculture and health.

[Ab] Resumo:We describe Tuccioglyphus setosus gen. et sp. nov. from the litter of commercially reared laying hens as well as wild birds in Brazil. The new genus Tuccioglyphus presents a mixture of character states between the two conventional subfamilies, Pyroglyphinae and Dermatophagoidinae. Based on this new unusual genus, we discuss character states delimiting these and other major subfamilies of the house dust mite family, Pyroglyphidae, as well as its most important and species-rich genus Dermatophagoides. An additional new genus, Marioglyphus gen. n., is proposed for Hughesiella valerioi Vargas and Smiley. Both Tuccioglyphus and Marioglyphus are related to the genus Hughesiella. A key to pyroglyphid genera of the World is presented.

[Ti] Título:Draft genome of the honey bee ectoparasitic mite, Tropilaelaps mercedesae, is shaped by the parasitic life history.
[So] Source:Gigascience;6(3):1-17, 2017 Mar 01.

[La] Idioma:eng
[Ab] Resumo:The number of managed honey bee colonies has considerably decreased in many developed countries in recent years and ectoparasitic mites are considered as major threats to honey bee colonies and health. However, their general biology remains poorly understood. We sequenced the genome of Tropilaelaps mercedesae, the prevalent ectoparasitic mite infesting honey bees in Asia, and predicted 15 190 protein-coding genes that were well supported by the mite transcriptomes and proteomic data. Although amino acid substitutions have been accelerated within the conserved core genes of two mites, T. mercedesae and Metaseiulus occidentalis, T. mercedesae has undergone the least gene family expansion and contraction between the seven arthropods we tested. The number of sensory system genes has been dramatically reduced, but T. mercedesae contains all gene sets required to detoxify xenobiotics. T. mercedesae is closely associated with a symbiotic bacterium (Rickettsiella grylli-like) and Deformed Wing Virus, the most prevalent honey bee virus. T. mercedesae has a very specialized life history and habitat as the ectoparasitic mite strictly depends on the honey bee inside a stable colony. Thus, comparison of the genome and transcriptome sequences with those of a tick and free-living mites has revealed the specific features of the genome shaped by interaction with the honey bee and colony environment. Genome and transcriptome sequences of T. mercedesae, as well as Varroa destructor (another globally prevalent ectoparasitic mite of honey bee), not only provide insights into the mite biology, but may also help to develop measures to control the most serious pests of the honey bee.

[Ti] Título:Complex Evolutionary Dynamics of Massively Expanded Chemosensory Receptor Families in an Extreme Generalist Chelicerate Herbivore.

[Is] ISSN:1759-6653

[La] Idioma:eng
[Ab] Resumo:While mechanisms to detoxify plant produced, anti-herbivore compounds have been associated with plant host use by herbivores, less is known about the role of chemosensory perception in their life histories. This is especially true for generalists, including chelicerate herbivores that evolved herbivory independently from the more studied insect lineages. To shed light on chemosensory perception in a generalist herbivore, we characterized the chemosensory receptors (CRs) of the chelicerate two-spotted spider mite, Tetranychus urticae, an extreme generalist. Strikingly, T. urticae has more CRs than reported in any other arthropod to date. Including pseudogenes, 689 gustatory receptors were identified, as were 136 degenerin/Epithelial Na+ Channels (ENaCs) that have also been implicated as CRs in insects. The genomic distribution of T. urticae gustatory receptors indicates recurring bursts of lineage-specific proliferations, with the extent of receptor clusters reminiscent of those observed in the CR-rich genomes of vertebrates or C. elegans Although pseudogenization of many gustatory receptors within clusters suggests relaxed selection, a subset of receptors is expressed. Consistent with functions as CRs, the genomic distribution and expression of ENaCs in lineage-specific T. urticae expansions mirrors that observed for gustatory receptors. The expansion of ENaCs in T. urticae to > 3-fold that reported in other animals was unexpected, raising the possibility that ENaCs in T. urticae have been co-opted to fulfill a major role performed by unrelated CRs in other animals. More broadly, our findings suggest an elaborate role for chemosensory perception in generalist herbivores that are of key ecological and agricultural importance.

[Ti] Título:Ocular symptoms reported by patients infested with Demodex mites.

[La] Idioma:eng
[Ab] Resumo:The purpose of this study was to determine subjective ocular symptoms occurring in patients infested with Demodex. The number of Demodex mites in the obtained material that correlated with the appearance of ocular symptoms was estimated. The study material were eyelashes collected from 1499 patients. The material were observed under a light microscope. T-test, the logistic regression method, and Pearson correlation coefficient were used for the analysis. Demodex mites were detected in 47% patients. The mean ages of infected women and men were 64 and 59 years, respectively. 64% infected patients complained of one or more ophthalmological symptoms. The most commonly reported symptoms included itching (28%), redness of eyelids (21%), and watery eyes (15%). Positive correlation was found between itching, redness, pain, purulence or eyelash loss and the presence of Demodex. The mentioned symptoms increase the probability of Demodex infestation in a statistically significant manner (p<0.005). A correlation between the age and gender and the number of Demodex was revealed by the study. The threshold average number of seven Demodex mites per eight collected eyelashes with which the risk of the occurrence of an ocular symptom increases significantly was defined. In patients with a low number of Demodex mites, symptoms may be absent. The risk of the occurrence of ocular symptom in patients with demodicosis increases with the increase in the average number of Demodex mites.
