Biological Sciences Theses & Dissertations
The Rocky Mountain wood tick, Dermacentor andersoni Stiles, injected with (u-14c) sodium acetate or DL-(benzene ring-u-14c) tryptophan for in vivo studies, was found to produce sex pheromone, 2,6-dichlorophenol, containing 14c activity. Ambiguous results were obtained with L-(u- 14c) tyrosine, and no incorporation of 14c label into pheromone was observed with DL-(ring-u- 14c) phenylalanine or DL-(side chain-3-14c) tyrosine. Attempts were made to determine the site of synthesis, but in vitro studies proved inconclusive.
Disruption of sex pheromone activity in D. andersoni and the American dog tick, D. variabilis (Say) was achieved …

Gastrointestinal Cestodes And Nematodes Of Coyotes From Southeastern Illinois, Valerie Keener
Masters Theses
Gastrointestinal tracts of 45 coyotes, Canis latrans, from southeastern Illinois were examined for cestodes and nematodes. The following parasites and incidences (%) were observed: Taenia sp. (71.1); Physaloptera sp. (53.3); Ancylostoma sp. (20.0); Ascarididae (11.1); Thelazia sp. (2.2); Trichuris sp. (2.2); Uncinaria sp. (2.2). Ancylostoma sp. occurred significantly more often in juveniles than adults. Parasites averaged low numbers per coyote, and no ulceration or blood in the tracts was seen.
