Procedure:
1. Place glass plates or other ceramic plates in freezer or refrigerator.
2. Assemble apparatus as shown with test tube approximately one-fourth full of water.
3. When ready, 1/4–1/2 of an Alka-Seltzer® tablet into the test tube. CO2 gas will immediately
be generated.
4. Quickly insert pipet tip between wall of culture vial and foam or cotton stopper.
Culture vial should be lying on its side.
5. If bubbles enter the glass or rubber tubing, decrease the water volume and/or size
of tablet piece used.
6. When flies are anesthetized, transfer them to a cold plate for your observation with
a stereoscope. Flies will remain asleep for roughly 2 minutes.
Technique provided by Jeff Orlinsky, Warren High School, Downey, CA.
Safely Anesthetize Drosophila
Here’s a safe and simple way to put fruit flies to sleep without any

anesthetizing with a cold plate technique to give you time to
count and sex the flies.
