dc.description.abstractMales of the oriental fruit fly, Bactrocera dorsalis (Hendel), are attracted to and feed on methyl eugenol. The goal of the present study was to determine whether feeding on a methyl eugenol-bearing plant, papaya (Carica papaya L.) would result in a mating advantage for B. dorsalis males. Mating frequencies of males given access to flowers (treated) and flower-deprived males (control) were compared in trials conducted 2 and 7 d after treated males were exposed to the flowers. For both intervals, treated males accounted for a significantly larger number of matings than control males. A second experiment compared female attraction to control and treated males. When at a lek, males display vigorous wing-fanning behavior, presumably to increase dispersal of the sex pheromone. Floral feeding resulted in a significant increase in wing- fanning activity but did not appear to affect the attractiveness of the pheromonal signal per se. A field experiment revealed that male captures in methyl eugenol-baited traps were not reduced by prior feeding on papaya flowers.
