Given the ubiquity and evolutionary importance of parasites, their effect on the energy budget of mammals remains surprisingly unclear. The eastern chipmunk ( Tamias striatus (L., 1758)) is a burrowing rodent that is commonly infected by cuterebrid bot fly ( Cuterebra emasculator Fitch, 1856) larvae. We measured resting metabolic rate (RMR) and cold-induced Vo2-max (under heliox atmosphere) in 20 free-ranging individuals, of which 4 individuals were infected by one or two larva. We found that RMR was significantly higher in chipmunks infected by bot fly larvae (mean ± SE = 0.88 ± 0.05 W) than in uninfected individuals (0.74 ± 0.02 W). In contrast, Vo2-max was significantly lower in chipmunks infected by bot fly larvae (4.96 ± 0.70 W) than in uninfected individuals (6.37 ± 0.16 W). Consequently, the aerobic scope (ratio of Vo2-max to RMR) was negatively correlated with the number of bot fly larvae (infected individuals = 5.74 ± 1.03 W; noninfected individuals = 8.67 ± 0.26 W). Finally, after accounting for the effects of body mass and bot fly parasitism on RMR and Vo2-max, there was no correlation between the two variables among individuals within our population. In addition to providing the first estimate of Vo2-max in T. striatus, these results offer additional evidence that bot fly parasitism has significant impacts on the metabolic ecology of this host species.

AbstractA case is presented of infestation with the larvae of Dermatobia hominis (human bot fly). This case is unusual in that it provides an example of three different outcomes for separate lesions in the same patient; spontaneous resolution, conservative treatment and surgical intervention. It also illustrates that myiasis should be included in the differential diagnosis of any skin lesion of a patient returning from the tropics.

Modest Effect

We quantified the impact of bot fly larvae (Cuterebra fontinella) on the energy budget of their small-mammal hosts (white-footed mice, Peromyscus leucopus). We estimated the fluxes of water from the host to the parasite and from the parasite to the host by injecting infected hosts (or bot fly larvae) with tritiated water and measuring the uptake by the parasite (or the host). Using these fluxes, we then constructed a fluid flux budget for the host–parasite system, and estimated that a bot fly larva receives ca. 1% of the host's nutrient budget. We also found a 5% increase in the metabolic rate of infected hosts in the laboratory, but no such effect in the field. No effect of bot fly larvae on digestive efficiency or food consumption was detected; however, infected mice lost body mass during a field trial. We conclude that bot fly larvae have a relatively modest effect, although energetically stressed individuals, such as lactating females, could suffer substantially.
