Attraction of female and male oriental fruit flies to conspecific males and mating competition following consumption of zingerone and ethyl vanillate.

Floral volatiles containing methyl eugenol, raspberry ketone or zingerone (Z) are known to modulate interactions between Bulbophyllum orchids and Bactrocera fruit flies. Recently, flowers of Bulbophyllum elevatopunctatum containing ethyl vanillate (EV) as one of the volatile component, was observed...
