Plastic Response of Drosophila Mating Behaviours with or without predators.

Published on 2018-04-20T14:18:53Z (GMT) by Paul Knoops
Measures of <i>Drosophila melanogaster </i>courtship and copulation times for a mating pair either exposed to a (perceived) predation threat, or no threat of predation. The predator used for experiments is the Zebra Jumping Spiders (<i>Salticus scenicus</i>), that is separated from the mating pair by a layer of mesh between the top chamber (flies) and bottom chamber (spider). <div><br></div><div>Each Box is related to both treatment and age of flies, with Box A and B being used to measure courtship between predator and non-predator treatments. Here, courtship occurrence and the amount of time courting was recorded in 15 minutes for a 2 day old male <i>Drosophila </i>and a immature virgin female (>20 hours old, unreceptive to all mating). Having a non-receptive female allows for all changes in mating behaviour to be primarily male driven. </div><div><br></div><div>Box C and D were used to recored copulation latency, duration and occurrence. Here males and females are both 2 days old, and adjustments should be made by both in response to predation. </div><div><br></div><div>The last set of videos hold trimmed videos showing examples of courtship and copulation, as well as a suite of what are believed to be antipredator behaviours, indicating that the mating pair is aware of a perceived threat and can modify behaviours in response if necessary. </div><div><br></div><div>All trials were completed between April 11th and 16th, 2016.</div>
