A Review of the Family Cheyletiellidae (Acarina)

Aspectos da associação forética dos ácaros Myialges spp. (Astigmata: Epidermoptidae) e Ornitocheyletia hallae Volgin (Prostigmata: Cheyletidae) com a mosca Pseudolynchia canariensis (Macquart) (Diptera: Hippoboscidae)

“…Os estágios móveis dos ácaros foram clarifi cados e montados em lâminas (segundo Flechtmann 1975) para identifi cação, feita sob microscópio fotônico com contraste de fases, usando-se as chaves de Furmann & Tharshis (1953), Smiley (1970) e Fain (1981.…”

Invasion of a House by the Dog Parasite <i>Cheyletiella yasguri</i> (Smiley 1965), a Mite Causing Prurigo in Man

“…The family Cheyletiellidae (Volgin 1966) consists of 33 species which are all parasitic on mammals and birds. Of the genus Cheyletiella, the only genus that is connected with human skin disease, five species are known: C. parasitivorax (Megnin 1878) and C.furmani (Smiley 1970) from rabbits, C. strandtmanni (Smiley 1970) from hares, C. hlakei (Smiley 1970) from cats as seen under a phase-contrast microscope, with a detail of a left genu L showing heart-shaped sensory seta. van Bronswijk/Jansen/O phof Invasion of a House by the Dog Parasite and C. yasguri (fig.…”

“…2) from dogs. These species can be separated under the phase-contrast microscope by means of the shape of the sensory seta of genu I [Smiley, 1970].…”

“…In fact, Cheyletiella sp. have been seen to prey upon other mites in the fur of mammals [Smiley, 1970]. More frequent, however, the pearcing chelicerae are used to suck fluid from the host, while the hooked palps dig into the skin.…”

“…The following species of mites were found in reasonable numbers in 0.1 g of dust: from the corridor and living room floor 6 Cheyleliella yasguri ) and 1 Dermatophagoides pleronyssimis (Trouessart 1897); from the furni ture 17 C. yasguri and 4 D. pleronyssimis; from the mattress 1 C. yasguri and 7 D. pteronyssinus. D. pleronyssimis is a common mite in houses in The Netherlands [van Bronswijk and Sinha, 1971]; C. yasguri, however, is a dog parasite that sometimes causes itching in man [Ewing et al, 1967;H ewitt el at., 1971;Rack, 1971;Smiley, , 1970, This forced us to examine the dog in spite of its healthy appearance and the results of the previous examination by the veterinarians. …”
