From Feb.-Apr. 1999, 19 species of ectoparasitic arthropods (2 sucking lice, 4 fleas, 4 ticks, 2 mesostigmatid mites, 5 chiggers, 2 fur mites) were recovered from 106 rodents belonging to 5 species (cotton mouse, Peromyscus gossypinus, n = 64; cotton rat, Sigmodon hispidus, n = 23; eastern woodrat, Neotoma floridana, n = 9; golden mouse, Ochrotomys nuttalli, n = 9; eastern gray squirrel, Sciuru...

The genome of the spider mite Tetranychus urticae, a herbivore, is missing important elements of the canonical Drosophila immune pathways necessary to fight bacterial infections. However, it is not known whether spider mites can mount an immune response and survive bacterial infection. In other chelicerates, bacterial infection elicits a response mediated by immune effectors leading to the surv...

SCABIES is a contagious skin disease caused by minute parasitic organisms known as mites. It affects cattle of all ages and breeds. Sometimes it is referred to as scab, mange, or barn itch. Similar infections attack other classes of livestock, wild animals, and birds, as well as people. Scabies, the medical term for which is acariasis, is common throughout the world. It generally causes a sever...

BACKGROUND Prenatal or embryonic learning, behavioral change following experience made prior to birth, may have significant consequences for postnatal foraging behavior in a wide variety of animals, including mammals, birds, fish, amphibians, and molluscs. However, prenatal learning has not been previously shown in arthropods such as insects, spiders and mites. METHODOLOGY/PRINCIPAL FINDINGS ...

We present a literature survey and analysis of the profile of mites (Acari, exclusive of Ixodida) in recent literature and on the World Wide Web, and compare their prominence to that of spiders (Araneae). Despite having approximately the same number of described species, spiders outshine mites on the Web, although the study of mites (Acarology) is better represented than the study of spiders (A...

Miniature inverted-repeat transposable elements (MITEs) are a specific group of nonautonomous DNA transposons, and they are distributed in a wide range of hosts. However, the origin and evolutionary history of MITEs in eukaryotic genomes remain unclear. In this study, six MITEs were identified in the silkworm (Bombyx mori). Five elements are grouped into four known superfamilies of DNA transpos...

A brief review of acari parasitizing reptiles (Reptilia) was presented. Reptilian mites are represented by 15 families of temporary and permanent parasites which belong to 3 orders: Mesostigmata (Entonyssidae, Heterozerconidae, Ixodorhynchidae, Laelapidae, Macronyssidae, Omentolaelapidae, Paramegistidae), Metastigmata (Amblyommidae, Argasidae, Ixodidae) and Prostigmata (Cloacaridae, Harpirhynch...

MITEs (miniature inverted-repeated transposable elements) are a particular class of defective DNA transposons usually present within genomes as high copy number populations of highly homogeneous elements. Although an active MITE, the mPing element, has recently been characterized in rice, the transposition mechanism of MITEs remains unknown. It has been proposed that transposases of related tra...

Mites of family Erythraeidae are parasites in their larval stage and predators in their post-larval stages on a variety of arthropods, among which are important pest species. During 2011-2013, in a faunistic survey of mites associated with beetles of the family Chrysomelidae in Oil and Gas company of Gachsaranregion, Iran. Specimens were preserved in AG (alcohol 75%, glyserin 5%), cleared in la...

Recent honey bee colony losses, particularly during the winter, have been shown to be associated with the presence of both ectoparasitic mites and Deformed Wing Virus (DWV). Whilst the role of Varroa destructor mites as a viral vector is well established, the role of Tropilaelaps mercedesae mites in viral transmission has not been fully investigated. In this study, we tested the effects that V....
