Feather mites (Astigmata: Pterolichoidea, Analgoidea) are permanent ectosymbionts of birds, found from all avian orders except Rheiformes (Stefan et al. 2015). The feather mites’ spatial distribution on the plumage depends on the morphology and structure of the feathers, aerodynamic and frictional forces, the life cycle and social behavior of the hosts, as well as environmental factors such as temperature and humidity (Dubinin 1951; Fernández-González et al. 2015). Depending on the location of the feather mites on the host’s body, a variety of morphological, physiological and behavioral adaptations are observed, which allow several feather mite species to coexist on the same bird (Dabert and Mironov 1999; Proctor 2003; Mestre et al. 2011). Studies dedicated to the spatial distribution of feather mites on the plumage of birds are relatively scarce. Such data is largely missing also for the territory of Bulgaria. Therefore, the aim of this paper is to present the results of the first specialized study of their spatial distribution on the plumage of passerines in Bulgaria. 379 birds belonging to 47 species of the order Passeriformes were examined in the period 2005–2007. As a result, the locations of 76,000 specimens (including both adults and nymphal stages) of feather mites of 54 species were determined. The distribution on the plumage of each species of bird was presented by generalized schemes. Feather mites were not found on the outermost primary feathers (P10), which are smaller than others primaries and do not offer enough resources. Feather mites located on the wing and tail feathers were mainly observed on the medial part of the feather, close to the rachis, and hence on the feather barbs. Feather mites preferred the wider parts of the primary feathers. On the secondary feathers, the mites were located predominantly in the middle third, on either side of the rachis. We examined if feather mites were symmetrically distributed on both wings using samples from those birds represented by numerous individuals (Passer montanus (L., 1758), Acrocephalus arundinaceus (L., 1758), Panurus biarmicus (L., 1758), Cyanistes caeruleus (L., 1758), Fringilla coelebs L., 1758). In this analysis, χ2-test confirmed no difference in the location of the feather mites on the feathers of both wings of the respective hosts and symmetry. Mites, such as Proctophyllodes pinnatus (Nitzsch, 1818) and Mesalgoides megnini (Oedemans, 1937) (on Chloris chloris (L., 1758)), Proctophyllodes stylifer (Buchholz, 1869) and Ptronyssoides parinus (Koch, 1841) (on Cyanistes caeruleus), Pterodectes rutilus Robin, 1868 and Scutulanyssus hirundicola Mironov, 1985 (on Hirundo rustica L., 1758), can coexist on the feathers of their respective hosts. Probably the different body size or trophology of these mite species reduced the competition between them. We found Trouessartia crucifera Gaud, 1957 and T. appendiculata (Berlese, 1886) on the secondary feathers of Hirundo rustica, but never together. The competition for resources between these two mite species is probably stronger. Feather mites respond to bird molting mainly by moving to adjacent feathers (Dubinin 1951). We monitored the spatial distribution of Proctohyllodes balati on the wing feathers during the molting of Panurus biarmicus.

Ecological interactions between mites (predatory and phytophagous) and wild plants growing in undisturbed environments play a crucial role to understand their natural settlement, development and dispersion patterns. Pequin chili pepper, Capsicum annuum L. var. glabriusculum, is a low-cost natural resource for local communities living inside Natural Protected Areas (ANP) of Tamaulipas State in Mexico. The aims of this research work were: 1) determine the spatial distribution pattern of predatory and phytophagous mites, 2) determine the spatiotemporal association between predatory and phytophagous mites, and 3) determine the association among different mite species and some phenological stages of Pequin chili pepper. The most abundant phytophagous mites were Tetranychus merganser and Aculops lycpoersici, and the predatory species were Amblyseius similoides, Euseius mesembrinus and Metaseiulus (Metaseiulus) negundinis. Most mite species showed an aggregated distribution pattern according to the plant phenological stages. However, the distribution of mite species throughout time showed different types of aggregation. On the other hand, we found positive associations among A. lycopersici and T. merganser phytophagous mites with A. similoides, E. mesembrinus and M. (M.) negundinis predators mites. The association between plants and mite species were influenced by the phenological stages of Pequin chili pepper. This is an indication of the complexity among trophic-chain interactions that depend largely on the available resources and competition. These two factors serve as foundations for settlement, development and dispersion patterns of certain species.

We present the results of our investigation of feather mites (Astigmata) associated with non-passerine birds in Brazil. The studied birds were obtained from roadkills, airport accidents, and from capitivity. Most ectoparasites were collected from bird specimens by washing. A total of 51 non-passerine species from 20 families and 15 orders were examined. Of them, 24 species were assessed for feather mites for the first time. In addition, 10 host associations are recorded for the first time in Brazil. A total of 101 feather mite species were recorded, with 26 of them identified to the species level and 75 likely representing undescribed species; among the latter samples, five probably represent new genera. These records allowed the first inference about the host and mite association of many species, as well as the first discussion about the geographical distribution of some feather mite taxa along the host distribution.

AbstractSpatial distribution studies in pest management identify the locations where pest attacks on crops are most severe, enabling us to understand and predict the movement of such pests. Studies on the spatial distribution of two mite species, however, are rather scarce. The mitesPolyphagotarsonemus latusandTetranychus bastosiare the major pests affecting physic nut plantations (Jatropha curcas). Therefore, the objective of this study was to measure the spatial distributions ofP. latusandT. bastosiin the physic nut plantations. Mite densities were monitored over 2 years in two different plantations. Sample locations were georeferenced. The experimental data were analyzed using geostatistical analyses. The total mite density was found to be higher when only one species was present (T. bastosi). When both the mite species were found in the same plantation, their peak densities occurred at different times. These mites, however, exhibited uniform spatial distribution when found at extreme densities (low or high). However, the mites showed an aggregated distribution in intermediate densities. Mite spatial distribution models were isotropic. Mite colonization commenced at the periphery of the areas under study, whereas the high-density patches extended until they reached 30 m in diameter. This has not been reported forJ. curcasplants before.

Feather mites are the most diverse avian ectoparasites. They mainly live on the plumage of birds, feeding on uropygial oil, and may occasionally cause skin irritation, especially on caged birds. Here we report the results of a survey of feather mites on wild birds of the Zoobotanical State Park of Teresina, Piauí, Brazil. The following mites were collected from seven bird specimens kept in the park from January to July 2017: Pandionacarus fuscus (Nitzsch, 1818) on the osprey (Pandion haliaetus); Freyana dendrocygni Dubinin, 1950 and Heterobrephosceles megathrix Peterson and Atyeo, 1977 on the white-faced whistling-duc (Dendrocygna viduata); Nyctibiolichus megamerus Atyeo, 1979 on the common potoo (Nyctibius griseus); Hieracolichus hirundo (Mégnin and Trouessart, 1884) on the harpy eagle (Harpia harpyja) and Hieracolichus sp. on the southern caracara (Caracara plancus). These findings increase the known ranges of the mite species, with four of them reported for the first time in Brazil.

We report on the first investigation of feather mites associated with birds living on the Barton Peninsula (King George Island, Antarctica). We found seven feather mite species of the superfamily Analgoidea from four host species. Two new species are described from two charadriiform hosts: Alloptes (Sternalloptes) antarcticussp. nov. (Alloptidae) from Stercorarius maccormicki Saunders (Stercorariidae), and Ingrassia chionissp. nov. (Xolalgidae) from Chionis albus (Gmelin) (Chionidae). Additionally, we provide partial sequences of the mitochondrial cytochrome c oxidase subunit I (COI), which was utilized as a DNA barcode, for all seven feather mite species.

To date, the feather mite family Ptyssalgidae (Acariformes: Analgoidea) has been known from a single species associated with hummingbirds (Apodiformes: Trochilidae). Here, based on our collecting in Mexico, we describe (i) a new genus and species, Tyrannoptyssalges striatus gen. n., sp. n., from a passerine host Tolmomyias sulphurescens (Passeriformes: Tyrannidae) and (ii) four new species of the genus Ptyssalges Atyeo and Gaud, 1979 from hummingbirds (Apodiformes: Trochilidae): Ptyssalges amaziliae sp. n. from Amazilia rutila (Delattre) (type host), A. candida (Bourcier & Mulsant) and A. yucatanensis (Cabot), P. anthracothoracis sp. n. from Anthracothorax prevostii (Lesson, R.), P. atyeoi sp. n. from Phaethornis longirostris (Delattre), and P. campylopteri sp. n. from Campylopterus curvipennis excellens (Wetmore). In addition, we redescribe Ptyssalges major (Trouessart, 1887), the type species of the genus, based on newly collected material from the type host, Eutoxeres aquila, from Panama. Standard morphological descriptions of all mite species are supplemented by CO1 barcoding sequence data. In the genus Ptyssalges, CO1 K2P interspecific genetic distances were 11.39–11.89%, while distances between the single species of Tyrannoptyssalges and species of the genus Ptyssalges were 16.34–17.87%. New, amended diagnoses for the family Ptyssalgidae and the genus Ptyssalges and a key to all known ptyssalgid species are provided. Preliminary hypotheses on the origin and ancestral host associations of ptyssalgids are briefly discussed.

AbstractTwo new genera and three new species of feather mites (Astigmata, Pterolichoidea, Analgoidea) are described from two closely related species of cockatoos, Cacatua galerita (type host) and C. sulphurea (Psittaciformes, Cacatuidae): Astrolabelichus caudatus gen. nov., sp. nov. (Pterolichidae), Psittophagus lacunosus sp. nov. (Pterolichidae), and Cacatualges microdiscus gen. nov., sp. nov. (Xolalgidae). The presence of the same set of mite species on these two species of parrots points to a very close affinity of Cacatua sulphurea and C. galerita and gives additional support for the recent hypothesis of the conspecificity of these birds.

High Diversity

Feather mites show a high diversity of distribution patterns on the wings of birds, but we are currently unable to make precise predictions about the distribution of mites on a given bird at a given time. This is especially intriguing because factors such as air turbulence, humidity, or temperature are already recognized as shaping feather mite distribution. We hypothesize that feather mites, rather than responding to single factors, respond at the same time to different constraints when deciding where to live. To test this hypothesis, we studied the distribution of mites along the wings of barn swallows ( Hirundo rustica L., 1758) in Europe before molting and in Africa during and after molt. Feather mite preferences shifted according to the stage of molt of the bird, with a pattern suggesting a clear compromise between being as close as possible to the non-molting distribution while avoiding the molt of the occupied feather and the early stages of growth of new feathers. Thus, we suggest that interacting factors, rather than single variables, must be studied to further advance the understanding of the distribution of feather mites on the wings of birds.

AbstractObligate symbionts may be genetically structured among host individuals and among phenotypically distinct host populations. Such processes may in turn determine within-host genetic diversity of symbionts, which is relevant for understanding symbiont population dynamics. We analysed the population genetic structure of two species of feather mites (Proctophyllodes sylviae and Trouessartia bifurcata) in migratory and resident blackcaps Sylvia atricapilla that winter sympatrically. Resident and migratory hosts may provide mites with habitats of different qualities, what might promote specialization of mite populations. We found high genetic diversity of within-host populations for both mite species, but no sign of genetic structure of mites between migratory and resident hosts. Our results suggest that, although dispersal mechanisms between hosts during the non-breeding season are unclear, mite populations are not limited by transmission bottlenecks that would reduce genetic diversity among individuals that share a host. Additionally, there is no evidence that host phenotypic divergence (associated with the evolution of migration and residency) has promoted the evolution of host-specialist mite populations. Unrestricted dispersal among host types may allow symbiotic organisms to avoid inbreeding and to persist in the face of habitat heterogeneity in phenotypically diverse host populations.
