Incidence of Louse-flies (Hippoboscidae) in Some Alaskan Birds
نویسندگان
چکیده
Information was gathered on'the incidence of hippoboscid louse-flies (Diptera, Hippoboscidae) on passerine birds in interior Alaska during 1987. Other authors have discussed louse-fly infestations in birds, but always in areas with less severe climatic conditions. The hippoboscid species found (Omithomya bequaertl} was described by Maa (1969) as a new species, and few data are available on abundance, hosts, or distribution. A total of 429 birds of 28 species was examined for louseflies. This paper documents 10 avian hosts, from five families; eight of those hosts are newly described. Adult louse-flies were found during a 70day period from 23 June through 29 August 1987.

In total, amongst the 213 species of this family known worldwide, 14 have been reported in Madagascar, among which six are considered as endemic to the Malagasy region. In addition, data are...
متن کاملArsenophonus and Sodalis replacements shape evolution of symbiosis in louse flies
Symbiotic interactions between insects and bacteria are ubiquitous and form a continuum from loose facultative symbiosis to greatly intimate and stable obligate symbiosis. In blood-sucking insects living exclusively on vertebrate blood, obligate endosymbionts are essential for hosts and hypothesized to supplement B-vitamins and cofactors missing from their blood diet. The role and distribution ...
متن کاملSources of variability in aggregation and sex ratios of Crataerina melbae (Diptera: Hippoboscidae) among adult colonial alpine swifts.
Aggregation of Crataerina melbae flies on breeding adult alpine swifts (Apus melba) was low when compared with other host-parasite systems and varied with sampling date, year, and sex of the flies. Generalized linear models were performed to ascertain which factors, extrinsic and/or intrinsic to the host, explained variability in the number of louse flies present on a single host, i.e., abundan...
