Fleas (Siphonaptera) Associated With Small Mammals Of Morocco Their Distribution And Host-Specificity, Michael W. Hastriter
Fleas (Siphonaptera) Associated With Small Mammals Of Morocco Their Distribution And Host-Specificity, Michael W. Hastriter
Theses and Dissertations
A total of 9,936 fleas, representing 27 species, have been processed for study and identified. They were associated with 2,011 small mammals, representing 38 species, collected throughout Morocco from October 12, 1969 to July 20, 1970 by personnel of the Smithsonian Institution. Two species, Synosternus cleopatrae pyramidis (Rothschild and Xenopsylla ramesis (Rothschild), comprised 68 percent of the fleas collected. Two subspecies are described: Ctenophthalmus andorrensis opistolatus, ssp. n. and Ctenophthalmus russulae tangerensis, ssp. n.. There are three ecological subdivisions of Morocco: the coast and coastal plains, the Atlas Mountains, and the pre-saharan desert. Even though there is some overlap, the …
Population Dynamics Of Fleas (Siphonaptera) On The Uinta Ground Squirrel, Spermophilus Armatus Kennicott, Dennis I. Anderson
Population Dynamics Of Fleas (Siphonaptera) On The Uinta Ground Squirrel, Spermophilus Armatus Kennicott, Dennis I. Anderson
Theses and Dissertations
The Uninta ground squirrel, Spermophilus armatus Kennicott, is the most abundant diurnal rodent in the Wasatch Mountains at the 7,000-9,000 foot level particularly in the campgrounds and picnic areas. Contact between man and the Uninta ground squirrel may be hazardous inasmuch as the causative agent of plague has been isolated from S. armatus and its flea parasites (Public Health Reports, 1937, 1938a, 1938b; Meyer, 1938; Byington, 1940; Allred, 1951; and Beck, 1955). Since these fleas are vectors of sylvatic plague and potential vectors of human plague, detailed knowledge about their population dynamics is desirable.
Bionomics And The Influence Of Diet Upon The Maturation Of Orchopeas Leucopus (Baker), Lynden Phillip Baum
Bionomics And The Influence Of Diet Upon The Maturation Of Orchopeas Leucopus (Baker), Lynden Phillip Baum
Theses and Dissertations
Knowledge of the bionomics of plague vectors, es-pecially factors which influence life history, host pre-ference, and fluctuations of flea populations, are basic to an understanding of plague ecology. Orchopeas leucopus (Baker), an ectoparasite of cricetid rodents such as Peromyscus maniculatus (Wagner), and Peromyscus truei (Baird), is a vector of plague in the western United States (Holdenried and Morlan, 1955). In a study of nine biotic corrnnunities in the Utah portion of the Great Basin, P. maniculatus was the most abundant rodent in seven of the biotic corrnnunities (Olsen, 1966). Because of the ubiquitous nature of P. maniculatus an interchange of …
