Fruit Flies In Hot, Cold, and Room Temperature

CSEF · 2013 Zoology

Aleeque Lori Marselian · Chamlian (Vahan & Anoush) Armenian School, Glendale, Los Angeles County

Overview

Objectives/Goals The objective of my project is to find the effect of temperature on the development time of a Drosophila melanogaster. My hypothesis is that as the temperature increases the development time of the drosophila melanogaster decreases. Methods/Materials First I set the food for the fruit fly on the bottom of each container. Then, I separated the male and female fruit flies. I put five female and five male flies in each container. I let the flies mate. Once they reproduced I took out the adult flies, leaving only the eggs. Lastly, I observed them for their development from egg to adult in their experimental temperatures. Results It was found that development times decrease at higher temperatures. It took the fruit flies in the cold temperature condition 22 days to develop, while it took the hot temperature fruit flies 11 days to develop. The flies in room temperature took about 12 days to develop.
