Abstract

We will investigate the sexual conflict in the stalk-eyed fly, Cyrtodiopsis dalmanni. We will use a combination of phenotypic manipulations, molecular analyses and experimental evolution to reveal the mechanisms that underlie conflict between males and females over multiple mating in this species. We will a) characterise the accessory gland fluid constituents of male stalk-eyed flies by performing sequence analysis of accessory gland-specific transcripts, identifying stalk-eyed fly homologues of D. melangaster accessory gland genes and examining the phenotypic responses of females to accessory gland proteins b) impose experimental evolution for increased and decreased sexual competitiveness (by varying the adult sex-ratio under optimal conditions for growth) and measure the subsequent responses of male and female stalk-eyed flies for a suite of morphological and life-history traits.
