The results of previous studies that showed that exposing mass-reared male Mediterranean fruit flies Ceratitis capitata (Wiedemann) to ginger root oil ('aromatherapy') increases the likelihood of mating with wild females were confirmed. The increased male success could be due to female responses to changes in male behavior or male pheromones. There were no significant differences in the types of courtship movements executed by males with and without aromatherapy. The durations of movements also did not differ when mass-reared males were paired with mass-reared females; however, when they were paired with wild females, there were a few, small differences. Previous studies indicated that the effectiveness of the male long-distance attractant pheromone is not affected by aromatherapy, but these studies did not consider pheromones released at close range during courtship, which behavioral analyses suggest may be different. We propose the following possible explanation for the different effects of aromatherapy with different females. Selection on males under mass rearing may have altered their close-range pheromones in ways that can be remedied by aromatherapy; and only wild females respond because the pheromonal responsiveness of mass-reared females has also changed. We propose observations that could test these ideas.

El aumento en el exito de los machos puede ser debido a las respuestas de las hembras a los cambios en el comportamiento o feromonas de los machos. No hubo una diferencia significativa en la clase de los movimientos del cortejo ejecutados por los machos con y sin la aromaterapia. La duracion de los movimientos tampoco fue diferente cuando los machos criados en masa fueron apareados con hembras criadas en masa; sin embargo, cuando ellos fueron apareados con hembras naturales, resultaron unas pequenas diferencias. Los estudios previos indicaron que la eficacia de la feromona atrayente de machos de larga distancia no esta afectada por la aromaterapia, pero estos estudios no consideran las feromonas sueltas en un rango corto durante el cortejo, cuando el analisis de comportamiento sugiere que puede ser diferente. Nosotros proponemos la explicacion siguiente para los efectos diferentes de la aromaterapia con las diferentes hembras. La seleccion de machos bajo condiciones de cria en masa puede haber alterado las feromonas de rango corto de manera que puede ser remediada por la aromaterapia; y solamente las hembras naturales responden por que tambien ha cambiado la respuesta de las hembras criadas en masa a la feromona. Nosotros indicamos observaciones que pueden probar estas ideas. (author)
