Abstract

Evidence is presented for the presence of a sex attractant in female Vitula edmandsae (Packard). The ability of the virgin female to attract the male varies with age, reaching a maximum 2 days after emergence.

The pheromone-producing gland is a ring-shaped structure formed by modification of the epidermal cells in the intersegmental membrane between the eighth and ninth abdominal segments.

Résumé

La femelle de Vitula edmandsae (Packard) (Lépidoptères : Phycitidées) produit du phéromone qui attire les mâles. La glande sécrétant cette substance n’est pas toujours active; elle atteint à un maximum deux jours après l’éclosion de l’adulte; elle a la forme d’un anneau produit par la modification des cellules épidermiques formant la membrane entre le huitième et le neuvième segment abdominal.
