Female mating with middle aged males obtains greater accessory gland proteins and sperms in Drosophila malerkotliana
Shivakumar P, Krishna M S
It was widely suggested that for species in which mating is resource independent female receive only accessory gland proteins and sperms in such species female should give concentration to age of mate to obtain benefits. D. malerkotliana on is one such species. In this species age effect of male on quantity of accessory gland proteins, sperm and post mating fitness benefits to Mated female has been studied. Outbred population of D. malerkotliana was used.It was noticed that females mated with Middle aged males obtains greater quantities of accessory gland proteins and sperm than females mated either with old or young males. As a result, females mated with middle aged males produced more eggs and progeny than those mated with older males. These studies indicate that in D. malerkotliana femalesobtain direct fitness benefit from mating with intermediate aged males.
