field trial of systemically delivered arthropod development-inhibitor (fluazuron) used to control woodrat fleas (siphonaptera: ceratophyllidae) and ticks (acari: ixodidae).an orally delivered arthropod development-inhibitory (fluazuron) was evaluated for its potential to reduce the number of flea and tick vectors found on the dusky-footed woodrat neotoma fuscipes baird, a reservoir host important in disease enzootiology in northern california. pigmented bait cubes containing fluazuron were distributed monthly to woodrat nests in a chaparral habitat for 1 yr. when compared with control woodrats, the numbers of fleas [primarily orchopeas sexdentatus (baker)] on trea ...200111268695
parasites and vector-borne pathogens of southern plains woodrats (neotoma micropus) from southern texas.from 2008 to 2010, southern plains woodrats (neotoma micropus) from southern texas, were examined for parasites and selected pathogens. eight helminth species were recovered from 97 woodrats including, trichuris neotomae from 78 (prevalence = 80%), ascarops sp. from 42 (43%), nematodirus neotoma from 31 (32%), raillietina sp. from nine (9%), taenia taeniaeformis larvae from eight (8%), and an unidentified spiurid, a scaphiostomum sp. and a zonorchis sp. each from a single woodrat. besnotia neoto ...201122108764
a longitudinal study of bartonella infection in populations of woodrats and their fleas.rodent-borne bartonellae have been identified as human pathogens. little is known about bartonella infections in woodrat hosts and their fleas and how woodrat-flea associations may affect the dynamics of bartonella infections. we collected blood samples and fleas from two species of woodrats (neotoma micropus and n. albigula) from santa fe county, nm, from 2002-2005. the most predominant flea species were orchopeas sexdentatus and o. neotomae. bartonella prevalence in woodrats was 64% overall, w ...200819263856
ectoparasite fauna of the eastern woodrat, neotoma floridana: composition, origin, and comparison with ectoparasite faunas of western woodrat species.we collected ectoparasites from eastern woodrats, neotoma floridana, from 3 sites in the southeastern united states: coastal south carolina, southeast georgia, and south-central georgia. twelve ectoparasite species were recovered from 47 woodrats in south carolina (5 ticks, 5 mites, 2 fleas), 13 from 35 woodrats in south-central georgia (1 tick, 10 mites, 2 fleas), and 4 from a small host sample (7) in southeast georgia (2 ticks, 1 mite, 1 flea). new state records are established for the listrop ...19979194815
factors affecting the seasonal abundance of ground squirrel and wood rat fleas (siphonaptera) in san diego county, california.abiotic and biotic factors affecting the seasonal abundance of 3 species of sylvatic fleas on their hosts were examined at 7 sites in san diego county, california. indices for oropsylla (diamanus) montana (baker) were usually highest on spermophilus beecheyi nudipes (huey) when < 18.4 degrees c (october-december), whereas those for hoplopsyllus anomalus (baker) were highest when > 18.4 degrees c (july-september). o. montana was affected most by ambient temperature (inversely for the coastal site ...19968840686
evaluation of permethrin-impregnated cotton balls as potential nesting material to control ectoparasites of woodrats in california.the dusky-footed woodrat, neotoma fuscipes baird is a natural reservoir of the lyme disease spirochete, borrelia burgdorferi johnson, schmid, hyde, steigerwalt & brenner, in california. to investigate the potential of host-targeted insecticide to control the tick vectors of b. burgdorferi, permethrin-impregnated or untreated cotton balls were distributed in metal cylinders as potential nesting material adjacent to 95 woodrat houses in chaparral-covered rangeland. laboratory experiments demonstra ...19968667381
flea, rodent, and plague ecology at chuchupate campground, ventura county, california.chuchupate campground in ventura county, california, was closed to the public for 18 years (1982 to 2000) because of uncontrolled vector fleas and persistent plague antibody titers in rodents. the primary purpose of this study was to clarify the plague ecology of chuchupate campground by identifying involved rodents and their vector fleas and by determining many of their ecological parameters: abundance, flea and host preferences and diversities, and flea seasonality. rodents and fleas were iden ...200212125863
a taxonomic review of the north american genus orchopeas jordan, 1933 (siphonaptera: ceratophyllidae: ceratophyllinae).the 20 named taxa assigned to the north american flea genus orchopeas jordan, 1933 are reviewed. four of these are treated as junior synonyms and the fifth as a nomen dubium. these are: orchopeas sexdentatus firemani hubbard, 1955 = orchopeas schisintus (jordan, 1929); orchopeas schisintus nevadensis (jordan, 1929) = orchopeas schisintus agilis (rothschild, 1905); orchopeas howardi bolivari barrera, 1955 = orchopeas howardi (baker, 1895); orchopeas howardi texensis eads, 1950 = orchopeas fulleri ...200011217216
