BEHAVIOUR OF THE MALE MEDITERRANEAN FLOUR MOTH, EPHESTIA KUEHNIELLA, FOLLOWING ATTRACTION TO A SOURCE OF FEMALE SEX PHEROMONE

Filter paper treated with an extract of virgin female Ephestia kuehniella was held in a stream of air, and its characteristics as a source of sex pheromone were inferred from a series of bioassays of the air stream. Air swept upwards through the entire cross section of an olfactometer chamber which held male E. kuehniella and filter paper treated with female extract was placed under the chamber to provide sex pheromone from a defined area on the floor (the target). Time‐response curves were plotted for a range of quantities of female extract at the target. Males flew to the target but often left and returned. The number of males on the target at any instant therefore represented a dynamic equilibrium between their rates of arrival and departure.
