Resumen:
Male and female age are importantfactors that can influence mating and remating behavior. Females candiscriminate against or prefer older males, but there have been relativelyfewer studies on how female and male age influence female remating. Here weshowed in wild flies of the Mexican fruit fly Anastrepha ludens (Loew), that younger females preferred to matewith younger males over older males, while older females were less selective, whenfemales were given a choice between males of different ages. Also, when given achoice between males of different ages, older females had longer copulationdurations than younger females. On the other hand, older males and females hadlower mating success, compared with young and middle-aged flies under no choiceconditions. However, middle-aged females mated faster compared to young femalesand young males mated faster compared to middle-aged males. Male age did notinfluence female remating, while female age strongly determined female remating,with no females remating whenthey were old. It isunclear if female receptivity mechanisms are switched off at older ages, or iffemales are reluctant to remate due to possible costs of mating. We discuss ourresults in terms of how male and female age can influence mating decisions.
