Introduction
Drosophila melanogaster, commonly known as fruit fly or vinigar fly coming under the family Drosophilidae. The normal life span of the flies are generally 30 – 60 days and it may vary depend upon the external conditions. These flies are sexually dimorphic. The female flies are comparatively bigger than the male flies. The males flies and females fly can be easily distinguish with size difference and the colour pattern. The male flies have a dark band on the abdomen. The presence of sex combs, a hair like structure present on the front legs of the male is also a special feature of male. The development time of the Drosophila is depending upon the temperature they are growing. It will take approximately 10 days to form an adult …show more content…
The stereotypical manipulations that can execute in flies were unparallel compare to any other multi cellular organisms and this enables the scientists to answer the precise questions about the behavior (Bellen and Tsuda 2010). The currently available genetics tools like Gal4/UAS system and the RNAi screening makes one to make accurate mutations and hand on controlled gene expression. The courtship rituals of male D. melanogaster have a special interest in the field of behavioral studies. It often contributed to the studies related to learning, memory, information processing and execution of various behaviors (Pavlopoulos et al. 2008). Recently many studies were carried out using D. melanogaster as model organism in the fields of phototaxis (Bellen et al. 2011), chemotaxis (Vosshal and Stocker 2007), aggression (Iliadi 2009), physical response to mechanical stimuli (Kernan 2007), escape behavior (Fotowat et al. 2009) and sex (Manoli et al. 2006; Dickson 2008). At a high extent these studies can reveal the key role of nervous system …show more content…
One of the main factors triggering the courtship is visual stimulation. The majority of studies in Drosophila related to the courtships were centered on males as they exhibit various behaviors during the courtship ritual. The various steps involve in the courtship ritual includes, following the female, tapping her with his forelegs, contacting her genitalia with his mouthparts, singing a species-specific courtship song, and bending his abdomen to copulate (Villella and Hall 2008). It is presumed that Drosophila females assess a courting male by ‘summating’ sensory cues for species type and fitness before sanctioning mating (Pavlou and Goodwin 2013). A virgin female fly has the ability to reject of accept the courting of males which decides the success of copulation. When the female decides to accept the male, she slows down, ceases rejection behaviors and opens her vaginal plate for copulation. After successful copulation, mated females become temporarily sexually unreceptive to further copulatory attempts, increasing their rate of egg-laying (Kubli
