Mate-Seeking Behavior of Ephestia cautella1

The almond moth, Ephestia cautella (Walker), mated as a result of extensive male flight and female calling which ensured that at least one moth was calling or flying during most flights or calling bouts, respectively. The flight paths of the males relative to the locations of the calling females and those of males in the absence of calling females suggest that, in still air, the sex pheromone simply intensified male search once he was within substantially less than 60 cm of a calling female.
