The genetic basis of pheromone titre in the pink bollworm moth, Pectinophora gossypiella (Saunders), was examined through artificial selection for females that produce greater amounts of the sex pheromone [a mixture of (Z, E )‐ and (Z, Z )‐7,11 ‐hexadecadieny 1 acetates]. Mean (±SD) pheromone titre increased by 91%, from 24.0±8.1 to 45.8±7.9 ng per female, in six generations of selection. No change in component ratio was observed within the selected line. The duration of male wing fanning, measured in a still‐air bioassay, did not change in the female‐selected line.
