Prevalence of adult and larval stages combined
Total parasite prevalence (i.e. presence of adult,
larval, or both parasite stages) varied significantly by
locality (logistic regression, p = 0.04), but was not significantly
affected by any of the other parameters
tested (p > 0.40). Since season was not a significant
factor (logistic regression, p = 0.43; Fig. 4a)
