Life Cycles: November 1

After a long weekend, many changes were noted in the cultures of fruit flies.

• Vestigal:
• Only two males were left alive in the vestigal culture. Because of this, we had to take flies out of the teacher's culture and add them to ours. Then, they were sexed in two groups. For the first group, there were 6 females and 10 males. For the second group, there were
• In the culture that had been contaminated with slime mold (which the adults had been separated from), metamorphic casings had appeared on the sides of the container and larvae were also visible within the food.
• Wild Type:
• Within the cultures for the wild type flies, the larvae had made metamorphic casings, while others were still scurrying around the food as worms.
• For the adults, only three were still alive, and had not laid any new eggs.
• White Eyed:
• The many adults that had been added to the white-eyed sample were still thriving, but had not laid any new larvae. Some were still visible in the food, but had not progressed to the stage where they made metamorphic casings

For future reference:
--While food should be kept in a one-to-one ratio, there should be less of the food and water added total. Because slime molds accumulate so quickly in the cultures, lessening the amounts of food might be beneficial to the prolonged survival of the flies.
