RESUMO

The ability of an organism to adapt to short-term environmental changes within its lifetime is of fundamental importance. This adaptation may occur through phenotypic plasticity. Insects and mites, in particular, are sensitive to changes in temperature and humidity, especially during the juvenile stages. We studied the role of phenotypic plasticity in the adaptation of eggs to different relative humidity conditions, in the predatory mite Phytoseiulus persimilis, used worldwide as a biological control agent of the spider mite Tetranychus urticae. The biocontrol efficacy of P. persimilis decreases under dry conditions, partly because P. persimilis eggs are sensitive to drought. We exposed P. persimilis adult females from two different strains to constant and variable humidity regimes and evaluated the hatching rate of their eggs in dry conditions, as well as the survival and oviposition rates of these females. Whereas the eggs laid by P. persimilis females exposed to constant high humidity did not survive in dry conditions, females exposed to constant low humidity started laying drought-resistant eggs after 24 h of exposure. Survival and oviposition rates of the females were affected by humidity: females laid fewer eggs under constant low humidity and had a shorter lifespan under constant high and constant low humidity. The humidity regimes tested had similar effects across the two P. persimilis strains. Our results demonstrate that transgenerational phenotypic plasticity, called maternal effect, allows P. persimilis females to prepare their offspring for dry conditions.

RESUMO

BACKGROUND: The tomato red spider mite, Tetranychus evansi Baker & Pritchard (Acari: Tetranychidae), is an agricultural pest of solanaceous crops. Although T. evansi is of South American subtropical origin, it has recently expanded its distribution range to many tropical and temperate areas around the world. Its potential distribution range in response to scenarios of global warming was recently modeled, confirming its current and possible future distributions. Here, we experimentally investigated the biological traits of T. evansi in the context of the current and future global warming (2100) scenarios. Using an environmental simulation system, we tested the life-history traits of T. evansi under current summer temperatures (as of June, July, and August 2016) and under expected temperature increases based on two IPCC scenarios: RCP2.6 (+ 1 °C) and RCP8.5 (+ 3.7 °C). The mites were introduced into each scenario on 1 June and their sequential progeny were used for testing in each following month. RESULTS: The mite could develop and reproduce under all scenarios. There was a decrease in the duration of lifespan and female fecundity at RCP8.5 during June and August, but this may be compensated for by the high intrinsic rate of increase, which implies faster population growth and shorter generation time. CONCLUSION: Our study and other reports reveal the high adaptability of T. evansi to a wide range of summer temperatures; this may explain its current distribution. We anticipate that global warming will favor the spread of T. evansi and may further expand its distribution to a large area of the globe. These findings should be of ecological and practical relevance for designing prevention and control strategies.

RESUMO

This paper presents a new genus, two new species, and several new records of mites associated with insects and soil in Cuba. A new monotypic genus of Laelapidae, Acantholaelaps gen. nov., is described to accommodate a new species, A. strategus sp. nov., on the basis of adult female and male specimens collected on Strategus sarpedon (Burmeister) (Coleoptera: Scarabaeidae) and Strategus surinamensis hirtus Sternberg (Coleoptera: Scarabaeidae). The other species recorded were Macrocheles merdarius (Berlese) (Macrochelidae), Asca quinquesetosa Wharton (Ascidae), Gaeolaelaps cubaensis sp. nov. (Laelapidae) and Pseudoparasitus missouriensis (Ewing) (Laelapidae).

RESUMO

Mites of the family Phytoseiidae are important predators for biological control applications. They occur naturally in ecosystems but their overall distribution is not completely known. This study presents results of surveys carried out in the south of France. It proposes the use of a combination of morphological and molecular approaches for species diagnosis. Eighteen species of the genus Typhlodromus are reported from southern France, of which nine belong to Typhlodromus (Anthoseius) and nine to Typhlodromus (Typhlodromus). Eight of these species are new to the French fauna. The mitochondrial DNA CytB gene from 85 specimens (18 species) and the 12S rRNA gene from 30 specimens (9 species) were partially sequenced and analysed. Based on molecular and morphological comparisons, the synonymy between Typhlodromus (Anthoseius) ilicis and T. (A.) creticus is discussed. High genetic distances between specimens morphologically assigned to T. (A.) rhenanoides suggests the existence of cryptic species. The reliability of integrative approaches for species identification is discussed.

RESUMO

The phylogeny of the mite genus Pterygosoma Peters, 1849 (Acariformes: Pterygosomatidae), permanent parasites of lizards of the families Agamidae, Gerrhosauridae and Liolaemidae (Reptilia: Squamata), was inferred with maximum parsimony, successive weighting and implied weighting approaches based on 182 characters of 48 ingroup and 12 outgroup species. All undertaken analyses questioned the monophyly of the genus. Based on this research, Pterygosoma includes 56 mite species associated with agamas from Africa and Asia (Sauria: Agamidae). Within the genus seven natural species groups were found: mutabilis, inermis, melanum, caucasica, fimbriata, singularis and foliosetis; 13 species of the genus were not assigned to any of the groups due to their unique morphological characters. For the ligare group of the subgenus Pterygosoma s. str. (7 species) associated with the South American tree lizards from the family Liolaemidae, a new genus, Neopterygosoma gen. nov., is established. The subgenus Gerrhosaurobia Lawrence, 1959 (3 species) associated with the African plated lizards of the family Gerrhosauridae is elevated to the genus rank. Diagnoses for the three genera are presented. Historical associations are reconstructed by fitting the obtained mite tree into the host topology on the family level. Results of coevolutionary analysis highlight the coincidence of both trees. The studies suggest that the ancestor of the genus Pterygosoma switched from the hosts of Gerrhosaurobia i.e. from the plated lizards (Gerrhosauridae) to the agamas (Agamidae), and the genus Pterygosoma has its biogeographic origin in North Africa, and colonized Asia via the Arabian Peninsula, which is congruent with the historical biogeography of its hosts.

RESUMO

As a first supplement to the list of the water mites (Acari, Hydrachnidia) fauna of Turkey compiled by Erman et al. (2010), a faunistic list of water mites from Turkey is presented based on published data after 2010. Including the new data, the total number of taxa recorded from Turkey reaches 335 species, in 62 genera and 25 families. The new synonym is established Trichothyas (Lundbladia) anatolica Boyaci Gülle, 2014 = Dacothyas kandilliensis Oezkan Bader, 1988. Furthermore, for each family, the number of species is given, both, for this study and totally.

RESUMO

Knowledge of the oribatid mite community from Patagonian steppe is scarce compared with other environments, such as the Andean-Patagonian forest. In the present research we identified oribatid mites under different environmental conditions: two Patagonian steppe types (grass and shrub), two soil characteristics (bare and covered soil) and two different seasons (autumn and spring). A total of 42 species/morphospecies were found, 13 were new records for Chubut and one was a new record for Argentina. In view of its ecological role in soil formation, it is fundamental that knowledge about this fauna is enhanced in order to provide baselines for study and to aid further understanding about its ecology.

RESUMO

Demodex are among the tiniest organisms in Acari and are important mammalian parasites. However, differences in pathogenicity between two human parasites, Demodex folliculorum and Demodex brevis, remain unknown. Related genetic studies are limited by RNA extraction difficulties and molecular data deficiencies. In this study, RNA extraction, de novo sequencing, functional annotation, and differential gene expression analyses were performed to compare D. folliculorum and D. brevis. This yielded 67.09 and 65.10 million clean reads, respectively, with similar annotations. Bioinformatics analyses and manual alignments identified 237 coding sequences comprising 48 genes from 29 families, including five important functional classes. Of these, 30 genes from 20 families related to metabolism, motion, detoxification and stress response, and allergic reaction were differentially expressed between the two species. Cathepsin type 1, serine protease inhibitor, arginine kinase, triosephosphate isomerase, muscle-specific protein 20-2, myosin alkaline light chain, troponin C, tropomyosin, and heat shock protein 90 were highly expressed in D. folliculorum, whereas cathepsin type 2, aspartic protease, serine protease, myosin heavy chain type 2, and alpha tubulin type 1C were highly expressed in D. brevis. Verified coding sequences were nearly consistent with unigene clusters. Further, absolute quantification results demonstrated that differentially expressed genes followed the predicted expression trend. Therefore, the first RNA sequencing and functional annotation analysis of two Demodex species was successful. Differential expression of important functional genes is likely implicated in pathogenicity disparities between these two species. Our study provides molecular data and technical support for further studies on human Demodex pathogenicity and functional genes.

RESUMO

Ololaelaps tasmanicus (Womersley, 1956) is redescribed from the holotype female and two additional female specimens from Australia. Ololaelaps elongatus Babaeian sp. nov. is described and illustrated from specimens from soil in Western Iran. The new species can be distinguished from the other congeners by four diagnostic morphological character states: (1) dorsal shield setae moderately long; (2) sternal shield elongate, almost reaching to level of mid-coxa IV, and fused with endopodals III-IV posterolaterally; (3) peritrematal shield posteriorly fused to exopodal shields IV, and free from genitiventrianal shield; (4) genitiventrianal shield with four pairs of pre-anal setae, Zv2 and Jv3 off shield. Additional notes on the holotype of Ololaelaps obovata (Womersley, 1960) and a key to the identification of species of Ololaelaps occurring in Iran are also presented. O. paratasmanicus Ryke, 1962 is considered as junior synonym of O. tasmanicus.

RESUMO

A bibliographical checklist of eriophyoid mites reported from Latvia is compiled. To date, 67 eriophyoid mite species associated with more than 29 plant genera have been recorded from Latvia. Many eriophyoid mite species previously reported in the literature were based on damage symptoms only rather than mite morphology. Some species records did not involve collecting and identifying actual specimens. To date, the majority of eriophyoid species documented from Latvia are associated with ornamental and wild woody plants with low commercial significance. Only damage caused by several Cecidophyopsis species, the pests of blackcurrants and redcurrants, is considered to be of economic significance, although in recent years Aculus fockeui (Nalepa Trouessart) has become a problem in plum orchards. Eriophyoid mites inhabiting herbaceous plants in Latvia have been poorly studied as only five species have been described. The present study shows that major revision is necessary for many of the eriophyoid mite species previously recorded.

RESUMO

The main morphological traits of Galumna lawrencei Jacot, 1940 stat. nov. and Galumna natalensis Jacot, 1940 stat. nov. (Oribatida, Galumnidae) are presented based on the type material from South Africa. We consider that these species are not subspecies of Galumna maxima as was proposed originally by Jacot 1940, but independent species. A lectotype for G. lawrencei is designated, due to the mixed-species cotype series.

RESUMO

Seven species of the feather mite genus Trouessartia Canestrini, 1899 (Astigmata: Trouessartiidae) have been recorded on swallows and martins (Passeriformes: Hirundinidae) in Manitoba (Canada). Of them, five are described as new species: Trouessartia ampulicaudata sp. n. and T. petrochelidon sp. n. from the American cliff swallow Petrochelidon pyrrhonota (Vieillot), T. bochkovi sp. n. from the tree swallow Tachycineta bicolor (Vieillot), and T. cryptocaudata sp. n. and T. progne sp. n. from the purple martin Progne subis (Linnaeus). A new species group stelgidopteryx, incorporating Trouessartia species living on hirundinids of the genera Progne, Tachycineta and Stelgidopteryx, is established. Renewed diagnoses of four Trouessartia species groups (appendiculata, crucifera, minutipes, and stelgidopteryx) restricted to hirundinids and a key to species recorded so far and potentially expected on swallows of North America are proposed. Host associations of Trouessartia species with swallows in North America are briefly discussed.
