A Survey Of Ectoparasites From Microtus Ochrogaster Ochrogaster (Wagner), Peromyscus Leucopus Noveboracensis (Fisher), And Cryptotis Parva Harlani (Say), Fred Basolo Jr.
A Survey Of Ectoparasites From Microtus Ochrogaster Ochrogaster (Wagner), Peromyscus Leucopus Noveboracensis (Fisher), And Cryptotis Parva Harlani (Say), Fred Basolo Jr.
Masters Theses
Ectoparasites were taken from 50 white footed deer mice, Peromyscus leucopus noveboracensis (Fisher), 50 prairie voles, Microtus ochrogaster ochrogaster (Wagner), and 11 least shrews, Cryptotis parva harlani (Say), within a five mile radius of Charleston, Illinois from 23 January 1973 through 25 June 1973. A total number of 4,242 ectoparasites were recovered; 2,395 from Microtus ochrogaster, 542 from Peromyscus leucopus, and 1,305 from Cryptotis parva. The major groups of ectoparasites and their percent recovery were: Acari (excl. of Metastigmata) 81.50%, Metastigmata 2.95%, Anoplura 15.50% and Siphonaptera 0.50%. A study of the ectoparasites recovered revealed representatives of 18 …
Parasites From Gizzard Shad, Dorosoma Cepedianum, In Lake Charleston, Illinois, Francis M. Yabai Kaikumba
Parasites From Gizzard Shad, Dorosoma Cepedianum, In Lake Charleston, Illinois, Francis M. Yabai Kaikumba
Masters Theses
Eighty gizzard shad (Dorosoma cepedianum) from Lake Charleston, Charleston, Illinois were examined for parasites. Eight fish were parasitized. Three fish contained the acanthocephalan Tanaorhamphus longirostris, three fish harbored cestodes of the genus Glaridacris and two fish had the nematode Camallanus oxycephalus. The latter is here reported for the first time from gizzard shad. Twenty fish were infected with the fungus Saprolegnia sp. The numbers of helminth parasites harbored by shad are less than reported for other forage fish. However, the incident of parasitism reported in this study is greater than that reported by previous workers.
Gastro-Intestinal And Abdominal Helminths Of White-Tailed Deer (Odocoileus Virginianus) From Carroll And Jo Daviess Counties In Northern Illinois, Jeffrey Joseph Hodge
Gastro-Intestinal And Abdominal Helminths Of White-Tailed Deer (Odocoileus Virginianus) From Carroll And Jo Daviess Counties In Northern Illinois, Jeffrey Joseph Hodge
Masters Theses
Forty-four white-tailed deer shot by hunters in November and December, 1971, in Carroll and Jo Daviess counties in northwestern Illinois were necropsied for gastro-intestinal and abdominal helminths. Five species of gastro-intestinal nematodes were found: Gongylonema pulchrum, Ostertagia odocoilei, Haemonchus contortus, Trichuris ovis and Nematodirus sp. Setaria yehi, a filiariad nematode, was found in the abdominal cavity. Moniezia benedeni was the only cestode found. No trematodes were recovered. Differences in numbers and kinds of parasites found in northern Illinois and southern Illinois are discussed. Prevalence increased with host age for certain species of parasites and decreased or …
Morphometric Variation In Aphelenchus Avenae Bastian, 1865 With Varied Nutrition And Time, John P. Kline
Morphometric Variation In Aphelenchus Avenae Bastian, 1865 With Varied Nutrition And Time, John P. Kline
Masters Theses
The effect of varied time, nutritional media, and species of fungus on taxonomic characters (L, a, b1, c, and V) of Aphelenchus avenae was investigated. The effect of these ecological conditions on morphometrics was variable; however, these characters varied significantly with increased time, decreased nutritional media, and species of fungus. The greatest number of morphometric changes occurred with increased time, and the fewest with species of fungus. With changing environmental conditions, “V” values were the most stable character.
