Chemo-anemotaxis: a behavioral response to sex pheromone in nonflying insects.

Abstract

The cockroach Periplaneta americana running on a Y-ring globe, moves downwind if an air current is directed toward the head. However, if the air current carries sex pheromone, then upwind movement is elicited. This orientation behavior is apparently a mechanism to facilitate the orientation of males searching for pheromone-secreting females.
