seasonal occurrence of haemoproteus columbae kruse and its vector pseudolynchia canariensis bequaert.seasonal prevalence of haemoproteus columbae and its vector pseudolynchia canariensis in the feral pigeon (columba livia) population of detroit, michigan has been studied for 5 years. the greated prevalence of h. columbae infection occurs during fall and winter and is lowest during the spring, correlating with changes in the vector population.1975803576
schizogony in haemoproteus columbae kruse.to fill in some of the gaps in our knowledge of schizogony of haemoproteus columbae kruse, transmission experiments involving inoculation into pigeons (columba livia gmelin) of sporozonites from salivary glands of the hippoboscid fly pseudolynchia canariensis (macquart) were carried out. we were unable to detect prepatent schizonts or to observe schizogonic development when infection became chronic. schizonts were mainly confined to lung tissue. observations of parapatent schizonts were made in ...1977410922
the ecto-, gastro-intestinal and haemo-parasites of live pigeons (columba livia) in kampala, uganda.in a study from october, 1996 to march, 1997, 34 pigeons in three different locations were studied for parasites. the majority of birds in nakulabye appeared clinically sick, while those within makerere university and wandegeya were apparently healthy. biometric data were taken for each bird and, during the process, ectoparasites were collected. faecal and blood samples were obtained. the study of ectoparasites revealed that pseudolynchia canariensis (the 'pigeon fly') was the most prevalent par ...199926911497
how effective is preening against mobile ectoparasites? an experimental test with pigeons and hippoboscid flies.birds combat ectoparasites with many defences but the first line of defence is grooming behaviour, which includes preening with the bill and scratching with the feet. preening has been shown to be very effective against ectoparasites. however, most tests have been with feather lice, which are relatively slow moving. less is known about the effectiveness of preening as a defence against more mobile and evasive ectoparasites such as hippoboscid flies. hippoboscids, which feed on blood, have direct ...201222787587
sex-specific effects of an avian malaria parasite on an insect vector: support for the resource limitation hypothesis.many parasites, such as those that cause malaria, depend on an insect vector for transmission between vertebrate hosts. theory predicts that parasites should have little or no effect on the transmission ability of vectors, e.g., parasites should not reduce vector life span as this will limit the temporal window of opportunity for transmission. however, if the parasite and vector compete for limited resources, there may be an unavoidable physiological cost to the vector (resource limitation hypot ...201223236915
an experimental test of the effects of behavioral and immunological defenses against vectors: do they interact to protect birds from blood parasites?blood-feeding arthropods can harm their hosts in many ways, such as through direct tissue damage and anemia, but also by distracting hosts from foraging or watching for predators. blood-borne pathogens transmitted by arthropods can further harm the host. thus, effective behavioral and immunological defenses against blood-feeding arthropods may provide important fitness advantages to hosts if they reduce bites, and in systems involving pathogen transmission, if they lower pathogen transmission ra ...201424620737

isolation, pure culture, and characterization of "candidatus arsenophonus arthropodicus," an intracellular secondary endosymbiont from the hippoboscid louse fly pseudolynchia canariensis.members of the genus arsenophonus comprise a large group of bacterial endosymbionts that are widely distributed in arthropods of medical, veterinary, and agricultural importance. at present, little is known about the role of these bacteria in arthropods, because few representatives have been isolated and cultured in the laboratory. in the current study, we describe the isolation and pure culture of an arsenophonus endosymbiont from the hippoboscid louse fly pseudolynchia canariensis. we propose ...200616598007
parasites of columba livia (aves: columbiformes) in tenerife (canary islands) and their role in the conservation biology of the laurel pigeons.the prevalence and intensity of the parasites from 50 wild doves (columba livia) from the city of santa cruz de tenerife, in the island of tenerife (canary archipelago), were studied. the following ectoparasites were found in apparently healthy pigeons (prevalences are shown in percentage (%) and mean intensities with their standard deviations): the acari dermanyssus gallinae (de geer, 1778) (6, 241.0 +/- 138.9) and tinaminyssus melloi fain, 1962 (10%, 218.3 +/- 117.3); the louses, columbicola c ...200415490756
are hippoboscid flies a major mode of transmission of feather mites?feather mites (astigmata) are distributed around the world, living on the feathers of birds, but their mechanisms for transmission among hosts are not fully understood. there is anecdotal evidence of feather mites attached to louseflies (diptera: hippoboscidae), suggesting that feather mites may use these flies as a mode of phoretic transmission among birds. two bird-lousefly associations (alpine swift apus melba-crataerina melbae and feral pigeon columba livia-pseudolynchia canariensis) were in ...200111695394
role of pseudolynchia canariensis in the transmission of haemoproteus turtur from the migrant streptopelia turtur to new bird hosts in egypt.pseudolynchia canariensis flies offered the naturally infected migrant dove streptopelia turtur with haemoproteus turtur succeeded to induce weak infection in the raised streptopelia turtur only. intraperitoneal, intramuscular and subcutaneous injection of their salivary glands together with intraperitoneal injection of macerated lung and liver tissues of infected doves revealed the appearance of low and moderate grade parasitaemia in s. senegallus and the raised s. turtur. flies offered laborat ...19989617059
bionomics and laboratory transmission of haemoproteus columbae kruse by pseudolynchia canariensis maquart (diptera: hippoboscidae) to two bird hosts in egypt.pseudolynchia canariensis succeeded to feed and survive normally on both streptopelia senegallus and s. turtur. the feeding period, blood meal ratio and longevity of both male and female flies did not differ significantly (p > 0.05) from the corresponding values for the natural host columba livia. infection of s. senegallus with haemoproteus columbae through flies bites, injection with either infected salivary glands suspension or infected macerated lung tissue of c. livia revealed a high parasi ...19989617043
a hitchhiker's guide to parasite transmission: the phoretic behaviour of feather lice.transmission to new hosts is a fundamental challenge for parasites. some species meet this challenge by hitchhiking on other, more mobile parasite species, a behaviour known as phoresis. for example, feather-feeding lice that parasitise birds disperse to new hosts by hitchhiking on parasitic louse flies, which fly between individual birds. oddly, however, some species of feather lice do not engage in phoresis. for example, although rock pigeon (columba livia) "wing" lice (columbicola columbae) f ...200919038259
walk or ride? phoretic behaviour of amblyceran and ischnoceran lice.phoresy is a behaviour where one organism hitches a ride on another more mobile organism. this is a common dispersal mechanism amongst relatively immobile species that specialise on patchy resources. parasites specialise on patchily distributed resources: their hosts. although host individuals are isolated in space and time, parasites must transmit between hosts or they will die with their hosts. lice are permanent obligate ectoparasites that complete their entire life cycle on their host. they ...201626896575
