dispersal of american house dust mites acari Pyroglyphidae in a residence
Journal of Medical Entomology, 1996Co-Authors: Judith A Mollet, William H RobinsonAbstract:American house dust mites, Dermatophagoides farinae Hughes, were marked by adding a 4% solution of Sudan Red 7B, a microbiological stain, to mite rearing media. Marked mites were released onto a downstairs couch in a 2-story residence. Two children sat on the couch for ≍3 h after which their clothes were examined for stained mites. Various parts of the house and family vehicle were vacuum sampled, and dust samples examined for presence of marked mites. Results of 2 trials showed the presence of marked mites on clothing, upstairs in the residence, as well as in the family vehicle. Clothing is shown to be a significant factor in the dispersal of American house dust mites. Even if concentrated in a small area (1 couch), mites were able to disperse throughout the house and into a family vehicle within a matter of weeks.

bioassay techniques for evaluating pesticides against dermatophagoides spp acari Pyroglyphidae
Journal of Medical Entomology, 1995Co-Authors: Judith A MolletAbstract:Three bioassay techniques for testing pesticides against the American house dust mite, Dermatophagoides farinae Hughes, and the European house dust mite, Dermatophagoides pteronyssinus (Trouessart), were evaluated using cypermethrin as a standard. All 3 bioassay techniques gave linear responses, and can be used for evaluation of different properties of compounds. The slide dip technique tests for contact activity, the plastic petri dish technique for residual activity on a nonporous surface, and the fabric technique for residual activity on a porous surface. The 2 species of house dust mites responded similarly to all 3 bioassays, indicating that these 2 species are equally susceptible to cypermethrin under a variety of test conditions. In further tests with the fabric technique, the composition of the fabrics used did not significantly affect the toxiciry of the compound tested.

Pyroglyphidae)—ectoparasites of passerine birds
2015Co-Authors: Andre V Bochkov, Pavel B. Klimov, Patrick GrootaertAbstract:The subfamily Onychalginae Fain, 1988 (Acariformes: Pyroglyphidae) is a monophyletic lineage comprising the closest parasitic relatives of the free-living pyroglyphid house dust mites. Onychalgine mites parasitize passerine birds of the fam-ilies Estrildidae, Passeridae, and Ploceidae in Africa and South America (a single record of Onychalges spinitarsis from a piciform bird requires confirmation). We revise this subfamily based on external morphology of adults and immature stages using light and scanning electron microscopy and give a key to species. Onychalginae includes 2 genera: Onychal

Tachornithoglyphus gen. nov.--a new genus of nidicolous Pyroglyphidae (Acariformes: Astigmata).
Zootaxa, 2015Co-Authors: Pavel B. Klimov, Andre V Bochkov, Barry M OconnorAbstract:Tachornithoglyphus gen. nov. (Acariformes: Pyroglyphidae) is established for Tachornithoglyphus tachornis (Cruz, Cuervo and Dusbabek, 1984), comb. nov. (transferred from Guatemalichus), collected from nests of the Antillean palm swift, Tachornis phoenicobia (Apodiformes: Apodidae) in Cuba. The new genus differs from the other four genera of the subfamily Guatemalichinae, Guatemalichus Fain and Wharton, 1970, Pottocola Fain, 1971, Fainoglyphus Atyeo and Gaud, 1977, and Capitonocoptes Fain and Gaud, 1984, mainly by having the length of solenidion σ1 of genu I less than one-third that of the segment (vs. solenidion σ1I at least half as long as genu I), by the absence of famulus e on tarsus I (vs. present), and by coxal apodemes Ia separated from each other and contiguous to the lateral parts of the epigynal arch (vs. posterior tips of apodemes Ia fused to each other and with the median part of the epigynal arch, or separated and contiguous to or fused with the median part of the epigynal arch). A detailed redescription of adults and tritonymphs of T. tachornis is provided.

Revision of the subfamily Onychalginae Fain, 1988 (Acariformes: Pyroglyphidae)-ectoparasites of passerine birds
Zootaxa, 2014Co-Authors: Andre V Bochkov, Pavel B. Klimov, Patrick GrootaertAbstract:The subfamily Onychalginae Fain, 1988 (Acariformes: Pyroglyphidae) is a monophyletic lineage comprising the closest parasitic relatives of the free-living pyroglyphid house dust mites. Onychalgine mites parasitize passerine birds of the families Estrildidae, Passeridae, and Ploceidae in Africa and South America (a single record of Onychalges spinitarsis from a piciform bird requires confirmation). We revise this subfamily based on external morphology of adults and immature stages using light and scanning electron microscopy and give a key to species. Onychalginae includes 2 genera: Onychalges Gaud and Mouchet, 1959 (6 species) and Paramealia Gaud, 1968 (1 species). The genus Kivuicola Fain, 1971 syn. nov. is synonymized with Onychalges , and its single species K. kivuana Fain, 1971 syn. nov. is considered as a putative synonym of O. odonturus Gaud, 1968. Onychalges spinitarsis (Fain and Gaud, 1984) is considered as a species inquirenda .

phylogeny and systematics of mammal associated psoroptidian mites acariformes astigmata psoroptidia derived from external morphology
Invertebrate Systematics, 2011Co-Authors: Andre V Bochkov, Sergey V MironovAbstract:We used morphological characters to explore the phylogeny of mammal-associated psoroptidian mites. In both maximum parsimony and Bayesian analyses, the clades uniting Psoroptoidea and Analgoidea–Sarcoptoidea (higher Psoroptidia) were strongly supported, and monophyly of most sarcoptoid families was confirmed. However, the relationships among families of the higher Psoroptidia (Analgoidea and Sarcoptoidea) remained poorly resolved. Two most parsimonious trees were obtained after successive weighting. In these trees, higher Psoroptidia split into two main clusters with Sarcoptoidea in the traditional sense shown as diphyletic. Cluster I consists of two superfamilies: Analgoidea, including Dermationidae, and Psoroptoidea, stat. res.: Psoroptoidinae (Turbinoptidae–Paracoroptinae); (Pandalurinae (Pyroglyphidae–Lobalgidae); Paralgopsidae, stat. nov.–Ptyssalgidae (Epidermoptidae–Psoroptidae). Cluster II consists of the superfamily Sarcoptoidea represented by two lineages: Listropsoralgidae, stat. nov. (Myocoptidae (Rhyncoptidae–Sarcoptidae)) and Dromiciocoptidae, stat. nov. ((Listrophoridae–Atopomelidae) (Chirodiscidae (Gastronyssidae (Pneumocoptidae–Lemurnyssidae)))). We hypothesised that mites of the superfamilies Pterolichoidea, Analgoidea and Psoroptoidea have independently colonised birds with subsequent ancestral shifts of the families Lobalgidae and Psoroptidae and subfamily Paracoroptinae from birds to mammals. Mites of the superfamily Sarcoptoidea switched from nidicoly to parasitism on ancestors of therian mammals and evolved exclusively on this host group.

development and fecundity of dermatophagoides farinae acari Pyroglyphidae
Journal of Medical Entomology, 1996Co-Authors: Larry G. Arlian, Jacqueline S DippoldAbstract:Duration of the life cycle at 16, 23, 30, and 35°C and fecundity at 23°C and 75% RH were determined for the American house dust mite, Dermatophagoides farinae Hughes. Lengths of the life cycles at 23 and 30°C were 35.6 ± 4.4 and 17.5 ± 1.2 d, respectively. Few eggs completed development to the adult stage at 16 and 35°C. At 23°C and 75% RH, the preoviposition period was 3.7 ± 1.1 d following emergence of the female from the tritonymph. The average reproductive period was 34.0 ± 10.7 d with a mean total of 65.5 ± 17.4 eggs produced per female. Female longevity after cessation of egg production was 63.3 ± 64.6 d.

survival fecundity and development of dermatophagoides farinae acari Pyroglyphidae at fluctuating relative humidity
Journal of Medical Entomology, 1998Co-Authors: Larry G. Arlian, Jacqueline S Neal, Sonia W BaconAbstract:We determined the survival, development, and fecundity of Dermatophagoides farinae Hughes exposed to fluctuating daily regimes of hydrating and dehydrating relative humidity. Larva emerged from 84, 92, and 94% of eggs incubated at a regime of 2, 4, and 8 h at 75% RH and 22, 20, and 16 h at 0% RH, respectively. No emerging offspring completed the life cycle when exposed to the 2 and 4 h of moist air daily but 44 and 53% survived for 70 d in the larval or nymphal stages, respectivley, and these completed development to adults when subsequently held at a constant 75% RH. Given 8 h of moist air daily, 41% of emerging offspring completed the life cycle but development was 1.6 times longer compared with development at a constant 75% RH. For all daily hydrating and dehydrating regimes, a greater percentage of offspring became males than females. Overall, survival of immatures was remarkable at these daily long periods of dehydrating conditions when a short period of hydrating moisture was provided. When exposed to a daily regime of 4 h of moist air (75% RH) and 20 h of dry air (0% RH), 84% of females survived 28 d and produced approximately 1/3 of the number of eggs produced at constant 75% RH (control).

transition matrix population model for dust mite dermatophagoides pteronyssinus acari Pyroglyphidae
Journal of Medical Entomology, 2009Co-Authors: M J CunninghamAbstract:A transition matrix model of the population dynamics of the European house dust mite, Dermatophagoides pteronyssinus (Trouessart) (Acari: Pyroglyphidae), is described. It can model continuously varying conditions by forming transition matrices by interpolation between known transition matrices constructed from experimental data. Finite carrying capacity is modeled by modifying the population distribution vector at each time-step by using a form of the Skellam model, which is derived from the assumption that in competition each successful animal gets all it requires, and the unsuccessful animals get insufficient resources for survival or reproduction. The transition matrix model does not require all mites to have the same survivorship, life-stage durations, fecundity, and so on. Life table data to drive the model is taken from two sources, one source of which requires using the mean and standard deviation of the duration of each stage to synthesize a range of duration times and a range of transition probabilities to the next stage, thus ensuring variability between mites. Where synthesized data are used, significant long-lasting oscillations in dust mite levels are modeled, which does not happen when modeling with unsynthesized data, and is unlikely to occur in the field. Under conditions normally met with in the microenvironment (bedding, base of carpet, soft furnishing) of D. pteronyssinus, finite carrying capacity is essential to prevent unbounded population growth. The model is compared with other workers' field data with fair agreement. It is argued that shortcomings in the available data rather than the model are the principal reasons for differences between field and modeled results.
