- Description:
- V práci je nastíněn jiný pohled na potravní specializaci půdních roztočů (která se projevuje jako značná) - pohled mikroanatomický, prováděný histologickou metodou, a to včetně fluorescenční a konfokální mikroskopie. Jako parametry se využívají: obsah trávicí soustavy, její aktivita dle sekrece enzymů, přítomnost hemocytů i extraintestinálních vnitřních bakteriálních těles, kultivace mikroorganismů z homogenátu a působení získaných bakteriálních enzymů na potravu, jmenovitě na vláknité půdní houby., This study examines the feeding habits of soil saprophagous mites from the point of view of microanatomy, using not only the histological method but also fluorescence staining and confocal microscopy. The research looks at a combination of the following factors: the alimentary tract, including its contents and secretion enzyme activity; the presence of hemocytes as well as internal extraintestinal bacterial bodies, all supplemented by purification of bacteria from the mite homogenate; and the impact of extracted bacterial enzymes on soil fungi., and Jaroslav Smrž.

3. Cystoidosoma hermaphroditus sp. n., the first representative of the quill mite family Ascouracaridae (Acari: Astigmata: Pterolichoidea) from an owl (Aves: Strigiformes)

- Subject:
- roztoči, parazitický hmyz, sovy, mites, parasitic insects, owls, 2, and 59
- Language:
- English
- Description:
- The mite family Ascouracaridae Gaud et Atyeo, 1976 contains large-sized mites (mostly > 1 mm) which live inside the quills of birds of several orders. To date, no representative of this family has been found associated with the order Strigiformes (owls). In this paper, a new species of this family, Cystoidosoma hermaphroditus sp. n., is described from the tropical screech owl, Megascops choliba (Vieillot) (Aves: Strigiformes) from Brazil. This species is unique in having an external spermaduct, a primary duct and a rudimentary bursa copulatrix present in males. This is the first astigmatan feather mite described from the order Strigiformes in this country. A key to adults of the genus Cystoidosoma Gaud et Atyeo, 1976 of the world is presented., Fabio Akashi Hernandes, Barry M. OConnor., and Obsahuje bibliografii

4. Hylomysobia gen. n. (Acari: Myobiidae), a new genus of mites parasitic on gymnures of the genus Hylomys (Eulipotyphla: Erinaceidae)

- Subject:
- mites, Myobiidae, parasites, Hylomysobia, gymnures, Hylomys, and systematics
- Language:

- Description:
- A new genus of Myobiidae, Hylomysobia gen. n. with two new species, H. mikhailzaitzevi sp. n. (type species) and H. chinensis sp. n., is described from gymnures of the genus Hylomys Müller (Eulipotyphla: Erinaceidae). The two species parasitize Hylomys suillus Müller from Cambodia and Vietnam, and Hylomys sinensis (Trouessart) from China, respectively. These species represent the first records of myobiid mites from species in the family Erinaceidae. The new genus differs from the closely related Eutalpacarus Jameson, 1949 by the following features: in both sexes, coxae I have a triangular process, setae ve are about three times wider than sce and c2, and coxae II bear two pairs of setae; in females, setae sci are lanceolate, setae ag1 and ag3 are absent, and the vulvar lobes are weakly developed; in males, setae e2 are absent, and setae c1, d1, d2 and e1 are situated on the genital shield. The life cycle of Hylomysobia spp. includes egg, larva, protonymph, deutonymph, and adults, male and female. In contrast to the most other myobiid genera possessing the tritonymphal stage, the deutonymphs of Hylomysobia moult directly to adults, and the tritonymphs are absent. Based on the restricted distribution of Hylomysobia species on hosts of this family (only on species of the genus Hylomys) and close morphological similarities to myobiids from Soricidae and Talpidae, it is suggested that the ancestor of this genus secondarily colonized the ancestor of Hylomys from moles or shrews.

5. Measuring and reporting life-cycle duration in insects and arachnids
- Creator:

- Type:
- article, model:article, and TEXT
- Subject:
- life-cycles, duration, rearing, instar, stage, demography, experimental design, statistics, insects, and mites
- Language:
- English
- Description:
- Some previous work on arthropod development is insufficiently detailed or incompletely reported. Much of the published information in this area is of limited use for the general analysis of life cycles. These difficulties arise primarily because many experiments do not control fully for the strain of the material (and even its specific identity) nor for rearing conditions, do not adequately take account of the complexity of life cycles and their stages, or are restricted to only part of the life cycle. For example, 285such factors as variable numbers of instars, sexual differences, abbreviated or hidden stages and dormancies may mean that the "average durations" reported apply to an unknown mixture of developmental types. Nor are experiments always designed or results reported and analysed in a logical and transparent manner. Undefined terms may obscure what actual developmental intervals were measured. Highly derived developmental or demographic measures may obscure core data. Statistical information may be inadequate. Such pitfalls are reviewed here, suggesting ways to ensure that results on the duration of development are both valid for specific studies and more widely useful. General experimental difficulties, recommended background information that should be provided, recommended life-cycle intervals and their terminology, and recommended ways to report numerical and statistical information are briefly summarized in tabular form.

6. Mesostigmatid mites associated with the dung beetle Copris lunaris (Coleoptera: Scarabaeidae)

- Type:
- article, model:article, and TEXT
- Subject:
- Acari, mites, Mesostigmata, phoresy, Copris lunaris, and Slovakia
- Language:
- English
- Description:
- We examined the mesostigmatid mites found in four nest chambers of the dung beetle Copris lunaris (Scarabaeidae) in Slovakia. A total of 763 mites was found, belonging to ten species. The most frequent and abundant species were Pelethiphis opacus, Macrocheles copridis, Parasitus copridis, Uropoda copridis, Copriphis pterophilus, and Onchodellus hispani. The nests contained 19 dung balls, each enclosing a beetle pupa. Altogether 472 mites were found in these brood balls. A further 291 mites were found on the parental beetles in the nests. Three mite species were clearly more abundant in brood balls than on parental beetles, and these belonged to the life cycle stage that disperses by phoresy. The mites found in brood balls apparently disperse on the young adult beetles when they emerge. Only Parasitus copridis was more abundant on parental beetles than in brood balls. Different species of mites have developed different strategies for dispersal, as shown by their preferential attachment to either the parental or progeny generations of beetles.

- Description:
- This study determined the scale of the phoresy of mesostigmatid mite by Ips typographus. Thirty pheromone traps in the Karkonosze National Park (Poland) caught 10,575 bark beetles on which there were 2,388 mesostigmatid mites belonging to eight species. The most numerous mites were Dendrolaelaps quadrisetus (1076 ind.) and Trichouropoda polytricha (1067 ind.). and Dariusz J. Gwiazdowicz, Jacek Kamczyc, Jerzy Bloszyk.
