GLYPTHELMINS-PENNSYLVANIENSIS (TREMATODA, DIGENEA) IN THE SPRING PEEPER, PSEUDACRIS-C-CRUCIFER (ANURA, HYLIDAE), FROM SOUTHWESTERN WEST-VIRGINIA

Fifty-one of 120 northern spring peepers, Pseudacris c. crucifer (Wied -Neuwied 1838), collected from 3 different habitats in Wayne County, W est Virginia were infected by Glypthelmins pennsylvaniensis Cheng, 196 1. The lowest mean intensity (2.5) of infection was recorded from host s in a temporary ditch habitat, while the highest mean intensity (8.9) was recorded for hosts collected in 1 of 2 marsh sites. There was no significant difference between the size (as weight) of infected versus uninfected hosts. There was a slight negative correlation between hos t weight and the number of G. pennsylvaniensis individuals present (i. e., larger hosts had fewer trematodes), but the regression coefficient was not significant (i.e., b = 0).
