Evolution of lure response in tephritid fruit flies: phytochemicals as drivers of sexual selection

► We studied lure effects on the mating behaviour and physiology of Bactrocera tryoni. ► Lure-fed males had high propensity to mate in no-choice and choice conditions. ► Females mated to lure-fed had higher fecundity and showed reduced remating. ► Longevity of lure-fed males and females mated to them was shorter than unfed rivals. ► Male lures are involved in sexual selection in Bactrocera tryoni.
