Influence of age, sex pheromone concentration and mating status on the response of Earias vittella and Earias insulana males to their female sex pheromone was studied using a T-shaped olfactometer. Males of both the species showed age related variation in their response to female sex pheromone and 4-day-old males were maximally responsive. Response of males of both the species to the female sex pheromone was concentration dependent and the level of response generally increased with an increase in pheromone concentration. In E. vittella, response of mated males was comparable with unmated males. In E. insulana, mating caused some reduction in the response of males.


On a étudié l’influence de l’âge, de la concentration de phéromone sexuelle et le status de l’accouplement sur la réponse des mâles Earias vittella et Earias insulana à la phéromone sexuelle femelle conspécifique en se servant de l’olfactomètre d’une forme T. Les mâles do toutes les deux espèces ont montré une variation ayant rapport à l’âge dans leur réponse à la phéromone sexuelle femelle et les mâles âgés de 4 jours étaient les plus réponsifs. La réponse des mâles de toutes les deux espèces à la phéromone sexuelle femelle dépendait de la concentration et le niveau de la réponse augmentait généralement avec l’augmentation dans la concentration de phéromone. En E. vittella, la réponse des mâles accouplés était comparable avec les males non accouples. En E. insulana, l’accouplement a résulté en un peu de réduction dans la réponse des mâles.
