Some aspects of the development of Philonema (Nematoda: Dracunculoidea) in Cyclops bicuspidatus ClausKo, Ronald Chun Chung January 1966 (has links)
Development of Philonema oncorhynchi and Philonema
agubernaculum in Cyclops bicuspidatus were followed and
compared by experimentally infecting the copepods with larvae
obtained from gravid female worms in spawning salmon and
trout. Larvae were dissected from copepods for examination
at an interval of two to three days. They were found to
undergo two moults in the copepods. Three larval stages are
described. All the larval stages of the two species of
Philonema are morphologically identical. The rates of
development of the larvae were observed to be directly
proportional to temperatures between 4° to 15°C. The Q₁₀ for the range was calculated as 4. The rates of development at 10° were the same in the two species. The effects of temperature on larval development are discussed. An attempt is made to correlate the rates of development of Philonema larvae in the copepods under laboratory conditions and the infection of sockeye salmon in Cultus Lake, British Columbia. / Science, Faculty of / Zoology, Department of / Graduate

Seasonal study of mites on deer mice (Peromyscus Maniculatus) in a Chaparral communityAsh, Donald B. 01 July 1963 (has links)
The parasitic mites on mammals living in the chaparral community of Utah are practically unknown ecologically. Keegan (1953) was the first to publish on parasitic mites from Utah. He listed mites of 12 species and 9 genera from Tooele and Juab counties from hosts which included one Peromyscus truei, five P. crinitus, and 20 P. maniculatus. Brennan and Beck (1955) published on the chiggers of Utah and included a key to 38 species. Allred (1954, 1956, 1957, 1958) studied the geographical distribution, seasonal occurrence, and biology of mites found on mice of the genus Peromyscus in Utah.
