| an experimental test of the site specificity of preening to control lice in feral pigeons. | site specificities of ectoparasites on the host may have evolved due to the selective pressure exerted by host grooming. the present study demonstrates that the efficiency of avian preening varies among sites on the host. the study relies on the simple idea that the effectiveness of preening behavior to control lice can be quantified by the removal rate of dead lice glued onto the feathers of living birds. two treatments were done to document site-specific differences in the efficiency of preeni ... | 1993 | 8277395 |
| [mallophaga of pigeons in cracow]. | infestation of columba livia domestica gmelin with mallophaga has been investigated in both, breeding and feral pigeons. all pigeons came from the area of cracow. five species of mallophaga have been distinguished: columbicola columbae columbae (l.), campanulotes bidentatus compar (burm.), coloceras damicornis fahrenholzi eichler, hohorstiella gigantea lata (piag.), neocolpocephalum (neocolpocephalum) turbinatum (denny). it appeared that the first two of the above-mentioned species showed the hi ... | 1996 | 8967083 |
| [ultrastructural surface properties in columbicola columbae s. str. (esthiopteridae, mallophaga-ischnocera) from domestic pigeons]. | all post-embryonal stages of columbicola columbae columbae (l.), the common parasite of pigeon, were investigated with regard to morphology, particularly surface ultrastructures. many qualitative characters differing c. columbae s. str. from the investigated up to now species of mallophaga were found in sem. they are among others double lateral protuberances of head (clavus and clavulus) as well as parallel sculpture of pore organs on the last two segments of antennae. the structures showed at t ... | 1996 | 8967084 |
| [observations on the vitality of lice from dead pigeons]. | experiments were carried out in july, september, october 1993 and january 1994 on 48 dead pigeons kept in cold storage (refrigerating machine) and at a window. the behaviour of mallophaga was observed. the insects left the feather after the cooling of the bird body, usually after 24 hours. the process lasted 3 days in cold storage conditions, while in outdoor (open-air) environment the mallophaga were still alive for another 14 days. the vitality of mallophaga is bigger in open-air, in moderatel ... | 1996 | 9012136 |

| ecomorphology of parasite attachment: experiments with feather lice. | the host specificity of some parasites can be reinforced by morphological specialization for attachment to mobile hosts. for example, ectoparasites with adaptations for attaching to hosts of a particular size might not be able to remain attached to larger or smaller hosts. this hypothesis is suggested by the positive correlation documented between the body sizes of many parasites and their hosts. we adopted an ecomorphological approach to test the attachment hypothesis. we tested the ability of ... | 2006 | 16629310 |

| oogenesis in phthirapterans (insecta: phthiraptera). i. morphological and histochemical characterization of the oocyte nucleus and its inclusions. | we characterize morphological and histochemical changes occurring within the oocyte nucleus (germinal vesicle) during oogenesis in two phthirapteran species: the pig louse, haematopinus suis (anoplura) and the pigeon louse, columbicola columbae (mallophaga). in previtellogenic oocytes, within the oocyte nucleus the chromatin condenses and forms the karyosome. in contact with the karyosome numerous dense and highly heterogeneous nuclear bodies occur. we demonstrate that these nuclear inclusions h ... | 2004 | 18089031 |
| host defence mediates interspecific competition in ectoparasites. | 1. interspecific competition influences which, how many and where species coexist in biological communities. interactions between species in different trophic levels can mediate interspecific competition; e.g. predators are known to reduce competition between prey species by suppressing their population sizes. a parallel phenomenon may take place in host-parasite systems, with host defence mediating competition between parasite species. 2. we experimentally investigated the impact of host defenc ... | 2008 | 18194262 |
| 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 ... | 2009 | 19038259 |
