Female insect pheromone blends induce robust tracking responses in males and direct them into traps. In vertebrates, pheromones that induce strong and precise tracking responses in natural habitats have rarely been described. Here, we show in the sea lamprey (Petromyzon marinus), a vertebrate invader of the Laurential Great Lakes, that a synthesized component of the male mating pheromone, 7alpha, 12alpha, 24-trihydroxy-5alpha-cholan-3-one 24-sulfate (3kPZS), when released into a stream to reach… CONTINUE READING
