Paraquat applications to spruce plantations for grass control had no effect on the movement or density of field mice Microtus arvalis) and voles (Microtus agrestis), but shrews (Sorex sp.) migrated from treated areas to untreated ones.

Small rodents depend on detection of a predator prior to actual contact. Thus, voles are sensitive to the scent of potential predators and respond to such odors without the necessity for other cues. In the wild, field voles Microtus agrestis) have been observed to avoid traps tainted with either weasel (Mustela nivalis) anal gland secretion or red fox (Vulpes vulpes) feces (Dickman Doncaster, 1984 Stoddart, 1976). Similarly, meadow and montane voles (M pennsylvanicus and M. montanus) were observed to avoid traps treated with the principal odiferous component of fox feces, 2,5-dihydro-2,4,5-trimethyl thiazoline (Sullivan, Crump Sullivan, 1988). The laboratory experiments discussed in the present chapter provided a quantitative assessment of locomotor activity levels following exposure to predator odor in laboratory-bred meadow voles.

Microtus agrestis. Table lb shows that a significantly smaller number of captures of M. agrestis are effected in traps scented with conspecific odor than in odorless traps. These data further confirm Stoddart s (1982a) data suggesting vole odor acts as an inhibitor to trap entry behavior.
