This study investigates the prevalence and effects of rodent botfly (Cuterebra) parasitism on deer mice (Peromyscus sonoriensis) and montane voles (Microtus montanus) in the Kenna Cartwright Nature Park, Kamloops, British Columbia. The research focuses on understanding the relationship between Cuterebra parasitism and host body condition, sex, and species, leveraging a 24-year dataset (2000-2024) of small mammal trapping conducted by NRSC 4040 students. Data analysis revealed that parasitized deer mice exhibited a statistically higher body mass compared to non-parasitized individuals, while no significant mass difference was found in montane voles. A sex bias was observed in deer mice, with females more frequently found with warbles. The study acknowledges a potential scientific bias due to the seasonal timing of rodent capture, as historical sampling was limited to the fall. This restricted temporal scope may skew the data, potentially missing variations in Cuterebra parasitism that could occur at other times of the year. While the limited sample size prevents conclusive findings on the effects of Cuterebra parasitism on hosts, the study still provides a crucial baseline by analyzing historical data. This foundation offers valuable insights for future research, particularly in exploring the long-term host-parasite dynamics of this particular ecological context.
