phthiraptera and gamasida parasites of columbina picui (temminck) (columbiformes: columbidae) in the state of rio grande do sul, southern brazil.thirty-two specimens of columbina picui (picui ground-dove) were examined, and a collection of arthropods was made by washing the external surface of the body and the nasal cavity. the species in the order phthiraptera found and their respective prevalences, mean abundance and mean intensity were: columbicola passerinae (84.4%; 10.3; 12.2), hohorstiella passerinae (21.9%; 0.7; 3.1) and physconelloides eurysema (3.1%; 0.1; 2). the gamasid mites found in the birds and their respective prevalences, ...201222990830
dermatitis caused by the tropical fowl mite ornithonyssus bursa (berlese) (acari: macronyssidae): a case report in humans.we herein report human dermatitis caused by the tropical fowl mite ornithonyssus bursa (berlese). the cases occurred in an apartment in a residential district of porto alegre city, state of rio grande do sul, brazil, where three members of the same family presented with pruritic lesions on the arms and legs. on inspecting the bathroom, several mites measuring approximately 1.0mm in length were observed coming from a nest of rufous hornero, furnarius rufus (gmelin). this is the first report of o. ...201526676510
survival and reproductive rate of mites in relation to resistance of their barn swallow hosts.parasite resistance may act via a number of different mechanisms that regulate or control the survival and the reproductive rate of parasites. observations and experiments were used to test for effects of host resistance on parasite survival and rate of reproduction. natural levels of infestation of barn swallow hirundo rustica nests by the tropical fowl mite ornithonyssus bursa were positively related to brood size, inversely related to the length of the outermost tail feathers of male nest own ...200028308772
sexual selection in the monogamous barn swallow (hirundo rustica). i. determinants of tail ornament size.the proportion of phenotypic variance in the length of the sexually selected tail of the monogamous barn swallow hirundo rustica that is attributable to genetic variance was studied in the field in denmark during a seven-year period. tail length was on average 20% greater in males than in females. tail length correlated with wing length, but not with other morphological traits. tail length increased with the first molt, but remained constant during subsequent years. changes in tail length betwee ...199128563968
effects of a haematophagous mite on the barn swallow (hirundo rustica): a test of the hamilton and zuk hypothesis.i tested three assumptions of the hamilton and zuk hypothesis (1982), which suggests that the extravagant male plumage of many bird species allows females to choose mates that are resistant to the parasites exploiting the host population at a given time. by choosing such males as mates, females will rear offspring carrying the genes for resistance. i tested three necessary conditions for the hamilton and zuk model: (1) whether parasites affect the fitness of their hosts; (2) whether there is her ...199028569014
avian mite dermatitis: an italian case indicating the establishment and spread of ornithonyssus bursa (acari: gamasida: macronyssidae) (berlese, 1888) in europe.avian mite dermatitis is a skin disease caused in mammals by the incidental bites of blood-sucking mites which customarily parasitize wild and domestic birds. it manifests in the form of pruritic, erythematous, or urticarial papules, with a central sting mark, in skin regions normally covered by clothing. the species mainly implicated in human bite cases are dermanyssus gallinae, ornithonyssus sylviarum and, less frequently, ornithonyssus bursa. the latter is mainly a tropical and subtropical mi ...201525660724
new hosts for the mite ornithonyssus bursa in argentina.the mite ornithonyssus bursa (berlese) (mesostigmata: macronyssidae) is considered a poultry pest causing important infestations in chickens and it is considered a potential vector of arbovirus. despite being considered a common parasite in wild birds, there is scarce published information about its potential hosts and effects on them. here we present new bird hosts for o. bursa, assess the presence of alphavirus, flavivirus and bunyavirus in mites from three host species, and discuss its potent ...201526258483
prevalence of dermanyssus and ornithonyssus species of mites in poultry farms of vikarabad area of hyderabad.the common blood feeder mites of poultry are from the genera dermanyssus and ornithonyssus. their presence are problematic for the producers either through potential direct effects on weight gain, egg production or sperm production in roosters or as nuisance pests on workers. they also cause anaemia in birds and play a vector role for several human and animal diseases. five poultry farm buildings of vikarabad area of rangareddy district were visited. samples were collected from a variety of site ...201627876951
a review of the ectoparasitic mites (acari: dermanyssoidea) associated with birds and their nests in slovakia, with notes on identification of some species.we review the parasitic mites of the superfamily dermanyssoidea found in the nests of slovakian domestic and wild birds (and a few mammals), compiled from new data and literature sources. three mite genera are included, namely dermanyssus dugès (dermanyssidae), ornithonyssus sambon and pellonyssus clark & yunker (macronyssidae), in which we recognised nine reliably documented species. pellonyssus is represented by one species, dermanyssus by five species, and ornithonyssus by three species. we c ...201425544512
haematophagus mites in poultry farms of iran.blood sucking mites are important avian ectoparasites which being found on bird species worldwide. their presence are problematic for the producers either through potential direct effects on weight gain, egg production, sperm production in roosters or as nuisance pests on worker handle hens and eggs. the aim of this study was pointing out of the status of haematophagus mites.200922808378
