Abstract

A statistically efficient method for field evaluation of predator attractants, utilizing scent-station transects, is described. The design permits simultaneous exposure of five candidate attractants and minimizes potential bias resulting from nonuniform distribution of predators, sequential visitation by predators in space or time, residual odors, nightly variation in predator activity, and prevailing winds and other meteorological conditions as they affect vititation rates. The transect visitation data are suitable for statistical analysis.
