Abstract Experiments designed to demonstrate the existence of a female sex‐pheromone in the pea midge, Contarinia pisi Winn. (Diptera: Cecidomyiidae) are described. Recordings from antennal receptors of males showed that extract of virgin females elicited an increase in spike activity. Field trapping experiments showed that traps containing virgin females or crude extract of virgin females caught large numbers of males. RÉSUMÉ Une phéromone sexuelle femelle de Contarinia pisi L'antenne des mâles de Contarinia pisi répond par électro‐antennogramme à un courant d'air contaminé par des femelles vierges. Des pièges contenant des femelles attirent de nombreux mâles.
