Number of ovulated females released, number entering within 0.5 m of 3kPZS or SMW (Responding), number swimming upstream of SMW (Pass natural), number that entered within 0.5 m of 3kPZS (Visit 3kPZS), and number that entered within 0.5 m of 3kPZS but did not enter within 0.5 m of SMW (Bypass natural). The time for ovulated females to swim 10 m upstream of acclimation cage (Respond), time spent within 0.5 m of natural pheromone (Natural), time spent within 0.5 m of 3kPZS (3kPZS), and swimming speed from SMW source to 3kPZS source. All times are medians. Binary variables evaluated with logistic regression and time variables evaluated with general linear model. Treatments that share a letter are not significantly different (two-tailed α = 0.05).
