... The burial of a cadaver results in reduced arthropod activity and disruptions in colonisation patterns. Here, the distribution and diversity of mite taxa was studied across decomposition stages of shallowly buried pig carcasses (Sus scrofa domesticus). In total 300 mites (88 species) were collected from three pig shallow graves compared to 129 mites (46 species) from control (bare) soil samples at ...
... The fauna of Mesostigmata in nests of the white stork Ciconia ciconia was studied in the vicinity of Poznań (Poland). A total of 37 mite species was recovered from 11 of the 12 nests examined. The mite fauna was dominated by the family Macrochelidae. Macrocheles merdarius was the most abundant species, comprising 56% of all mites recovered. Most of the abundant mite species were associated with du ...

Abstract:
... Carrion is an ephemeral and nutrient-rich resource that attracts a diverse array of arthropods as it decomposes. Carrion-associated mites often disperse between animal carcasses using phoresy, the transport of one species by another. Yet few studies have contrasted the dynamics of mite assemblages with other insect taxa present at carrion. We examined and compared the changes in abundance, species ...

Abstract:
... From different localities of the Balkan Peninsula and the Carpathian Basin altogether 19 macrochelid mite species are listed belonging to the genera Geholaspis Berlese, 1918 (three species), Glyptholaspis Filipponi et Pegazzano, 1960 (one species), Longicheles Valle, 1953 (four species), Macrholaspis Oudemans, 1931 (one species), Macrocheles Latreille, 1829 (five species), Neopodocinum Oudemans, 1 ...
... Many animals use behavioral defenses such as grooming to avoid or mitigate the negative effects of infection by ectoparasites. Grooming can be energetically costly and may trade off with other host activities. We hypothesize that self-grooming comes at a cost and, therefore, compromises future parasite resistance and other energetically expensive activities, namely flight. We measured the rates of ...

Abstract:
... Alpheus cedrici sp. n. is described based on two specimens collected under rocks while scuba diving off the coast of Ascension Island, central Atlantic Ocean. The new species belongs to the Alpheus macrocheles (Hailstone, 1835) species complex and appears to be most closely related to the eastern–central Atlantic Alpheus macrocheles, the western Atlantic Alpheus amblyonyx Chace, 1972, and the east ...
... Some members of the genus Spiroplasma are vertically transmitted endosymbionts of insects. Among them, Spiroplasma sp. Dhd, a member of the Spiroplasma poulsonii clade, is highly prevalent among worldwide populations of Drosophila hydei. Here we found that 53 out of 3,763 wild-caught D. hydei (1.4 %) were ectoparasitized by the mite that belong to the genus Macrocheles. Many of the ectoparasitized ...

Abstract:
... The stable fly, Stomoxys calcitrans (L.), is one of the main pests of livestock in Brazil, especially in areas where cattle is raised next to sugarcane (Saccharum spp.) fields in which vinasse is used as a fertilizer. Knowledge about the predatory mites associated with this parasite in the field may be helpful in designing programs to control it biologically. Mites of the family Macrochelidae are ...
... Habitat avoidance is an anti-parasite behaviour exhibited by at-risk hosts that can minimize exposure to parasites. Because environments are often heterogeneous, host decision-making with regards to habitat use may be affected by the presence of parasites and habitat quality simultaneously. In this study we examine how the ovipositing behaviour of a cactiphilic fruit fly, Drosophila nigrospiracula ...
... We test for fitness costs of resistance in a natural host-parasite system, involving Drosophila nigrospiracula and ectoparasitic mites, Macrocheles subbadius. We contrasted rates of mortality at embryonic and pupal stages of host ontogeny between replicate-resistant and -susceptible (control) lines at different temperatures (24, 28, and 34°C). Evidence for a cost of resistance was shown as a 17% o ...
... Parasites exert numerous effects upon their hosts, including physiological and metabolic changes that can in turn influence various aspects of host life history. Using flow‐through respirometry, we investigated how infection intensity of an ectoparasitic mite (Macrocheles subbadius) affects the respiratory rate (CO₂ production) of its host Drosophila nigrospiracula. Mean fly respiratory rate incre ...
... Numerous insects, including Drosophila nigrospiracula, that inhabit necrotic cacti of the Sonoran desert are host to Macrocheles subbadius, a cosmopolitan mesostigmatid mite. This paper shows that the mite pierces Drosophila integument and ingests haemolymph while attached to the abdomen of its host. Among field—caught flies, there was a strong negative relationship between mite load and wet mass ...
... Only two parasite interactions are known for Drosophila to date: Allantonematid nematodes associated with mycophagous Drosophilids and the ectoparasitic mite Macrocheles subbadius with the Sonoran Desert endemic Drosophila nigrospiracula. Unlike the nematode-Drosophila association, breadth of mite parasitism on Drosophila species is unknown. As M. subbadius is a generalist, parasitism of additiona ...

Abstract:
... Costs of resistance are expected to contribute to the maintenance of genetic variation for resistance in natural host populations. In the present study, we experimentally test for genetic trade-offs between parasite resistance and larval competitive ability expressed under varying levels of crowding and temperature. Artificial selection for increased behavioral resistance was applied against an ec ...

Abstract:
... The ‘ecology of fear’ describes the negative effects natural enemies have on potential victims even when those victims are not consumed or infected. Although recent work has demonstrated parasites have non-consumptive effects (NCE) on potential hosts, how these effects vary within host populations is not well understood. We investigated how NCE vary based on host risk of infection and relative cos ...

Abstract:
... Species of soil predatory mites feed on a diverse diet making them excellent biocontrol candidates for conservation biocontrol programs. Free-living nematodes (FLN) are commonly found in soils and serve as prey for many soil predatory mites, but as far as we know, have never been used as alternative prey to enhance the efficacy of soil predatory mites for conservation biological control. Our goal ...
... Mites should not be overlooked as a forensic tool, as many are commonly associated with decomposing animal matter and are closely associated with specific insect carriers and habitats. It is necessary to increase our understanding of the diversity of mites that are found in human and animal remains, their geographical distribution, and their population dynamics. This work is the first study of the ...

Abstract:
... Pest fly larvae and adults (Musca, Fannia spp.) and key predator arthropods (Macrocheles mites, Carcinops adults and Histeridae larvae, Staphylinidae larvae) were monitored for 2 yr on 3 southern California caged-layer poultry facilities. In each manure cleanout cycle, all manure rows were removed initially in normal removal houses (Normal), while half of the manure was left undisturbed in alterna ...
... A new species, Macrocheles kekensis sp. n., is described based from three specimens associated with a cetoniin beetle (Hoplia hungarica Burmeister, 1844). The new species differs from the other known European macrochelid species in having 29 pairs of dorsal setae, j1 and z1 short and robust, other dorsal setae long and pilose, and the absence of apodemes between the genital and ventrianal shields. ...

... We report 7 species of mesostigmatid mites associated to Dendroctonus rhizophagus. Samples were taken in the state of Chihuahua (June and July 2008–2011). The roots of Pinus arizonica were observed under the microscope to obtain mites associated to D. rhizophagus and their galleries.
