Working with supervisor Tom Price and his team, I carried out a research project investigating whether sleep patterns are affected by the battle of the sexes. The idea is that in species where females mate with multiple males, it is in the male’s interest if any female he mates with lays many eggs as quickly as possible, because after a while she will mate with another male who will father most subsequent eggs. So if males could force females to be active all day laying eggs, this would benefit the male. Normally, fruit flies are active only at dawn and dusk, so daylight egg laying might mean a female risks death due to predators or drying out. To test this, I put mated and unmated fruit flies into an activity monitor which, using an infrared beam, monitored the level of activity of each fly over a week. Entering this project, I had extremely limited experience of working with flies, so this project allowed the development of many new skills, including: sexing and identifying flies using microscopy, performing mating assays, food-making and maintaining fly stocks. Additionally, undertaking this project helped in gaining confidence, both in working in a different laboratory setting than usual with unfamiliar equipment (such as the activity monitor), and in working independently. Aside from my project, I also helped and worked alongside Tom Price’s team and attended team meetings, which helped me gain a valuable insight into the dynamic of a research group and the roles everyone plays. I enjoyed my project and working with the team very much and would definitely recommend taking part in a summer project.
